1 00:00:03,160 --> 00:00:06,680 Speaker 1: Ron An Inians. Sometimes there's glitches you can't explain, but 2 00:00:06,760 --> 00:00:09,560 Speaker 1: you've got to have the wherewifaal and the calmness and 3 00:00:09,640 --> 00:00:12,840 Speaker 1: to stand and deliver and just get through it. I 4 00:00:12,880 --> 00:00:16,160 Speaker 1: think that makes you go the car Doctor. There's an 5 00:00:16,239 --> 00:00:19,800 Speaker 1: idea for the web store. Is a car doctor calendar. 6 00:00:20,400 --> 00:00:23,279 Speaker 2: You and Danny's standing around in various stages of undress 7 00:00:23,320 --> 00:00:24,080 Speaker 2: working on cars. 8 00:00:24,160 --> 00:00:25,680 Speaker 1: Yeah, there you go, there's a thought to have. 9 00:00:25,920 --> 00:00:28,880 Speaker 3: Welcome to the radio home of ron An Aian, the 10 00:00:28,920 --> 00:00:32,360 Speaker 3: Car Doctor. Since nineteen ninety one, this is where car 11 00:00:32,440 --> 00:00:36,199 Speaker 3: owners the world overturned to for their definitive opinion on 12 00:00:36,280 --> 00:00:37,280 Speaker 3: automotive repair. 13 00:00:37,760 --> 00:00:39,199 Speaker 1: If your mechanics. 14 00:00:38,720 --> 00:00:41,279 Speaker 3: Giving you a busy signal, pick up the phone and 15 00:00:41,400 --> 00:00:43,840 Speaker 3: call in the garage doors. 16 00:00:43,600 --> 00:00:45,480 Speaker 1: Are open, but I am here to take your call 17 00:00:45,880 --> 00:00:48,360 Speaker 1: at eight five five five six ninety nine hundred and 18 00:00:48,440 --> 00:00:49,360 Speaker 1: now he. 19 00:00:51,960 --> 00:00:52,320 Speaker 3: Ronnie. 20 00:00:53,080 --> 00:00:55,920 Speaker 1: We've we've been very busy here in the shop and 21 00:00:56,240 --> 00:00:59,400 Speaker 1: car Doctor and and stuff. We're actually making some local 22 00:00:59,400 --> 00:01:02,320 Speaker 1: appearances around the country here in the New York area. 23 00:01:02,320 --> 00:01:05,000 Speaker 1: We're on War every other week or saw on the 24 00:01:05,000 --> 00:01:07,800 Speaker 1: Morning show. We're talking about what dashboard warning lights mean. 25 00:01:08,120 --> 00:01:12,399 Speaker 1: And this week we did our segment about check engine lights, 26 00:01:12,880 --> 00:01:15,920 Speaker 1: and it seems to us generated quite a stir A 27 00:01:15,920 --> 00:01:17,480 Speaker 1: lot of you are reacting to it. By the way, 28 00:01:17,520 --> 00:01:19,440 Speaker 1: if you're looking for the link, I think we're going 29 00:01:19,440 --> 00:01:21,160 Speaker 1: to get it up on the Facebook page, the link 30 00:01:21,200 --> 00:01:24,640 Speaker 1: to the WR conversation sometime this week. I know they're 31 00:01:24,640 --> 00:01:26,360 Speaker 1: going to get it up on Instagram. The social media 32 00:01:26,400 --> 00:01:28,440 Speaker 1: guys are a little behind right now, so bear with them. 33 00:01:29,080 --> 00:01:32,920 Speaker 1: But you can, you know, talking about check engine lights, 34 00:01:33,000 --> 00:01:34,880 Speaker 1: right and we talked about if it's steady, we talk 35 00:01:34,920 --> 00:01:37,160 Speaker 1: about if it's flashing, and then you know. And this 36 00:01:37,200 --> 00:01:39,280 Speaker 1: is what I love about you, know you guys, because 37 00:01:39,560 --> 00:01:42,520 Speaker 1: you ask You always ask such simple but very very 38 00:01:42,520 --> 00:01:46,039 Speaker 1: important questions. Sarah up on our Facebook page today said, 39 00:01:46,440 --> 00:01:48,720 Speaker 1: but what about the check engine light that's at random, 40 00:01:48,720 --> 00:01:51,200 Speaker 1: that shows up and then disappears and then comes back. 41 00:01:51,280 --> 00:01:53,680 Speaker 1: And you know, Sarah, I love you. It's a great question. 42 00:01:54,720 --> 00:01:57,720 Speaker 1: So when a check engine light comes on and goes away, 43 00:01:58,440 --> 00:02:02,680 Speaker 1: it means that the car saw a problem and then 44 00:02:02,720 --> 00:02:07,440 Speaker 1: the problem corrected itself. How does that happen? Well, it 45 00:02:07,480 --> 00:02:12,200 Speaker 1: depends on the situation. Every system and every sensor goes 46 00:02:12,280 --> 00:02:16,360 Speaker 1: through a constant evaluation. It's always testing behind the scenes 47 00:02:16,440 --> 00:02:18,839 Speaker 1: things that you don't see your experience, but it's there. 48 00:02:18,880 --> 00:02:22,640 Speaker 1: It's happening all right. If it's an evaporative emissions fault, 49 00:02:22,760 --> 00:02:26,120 Speaker 1: if it's a misfire issue, if it's a two centsor 50 00:02:26,120 --> 00:02:29,160 Speaker 1: sluggish to react, if it's a fuel trim problem, it's 51 00:02:29,200 --> 00:02:32,839 Speaker 1: always trying to correct and adjust and make it right. 52 00:02:33,200 --> 00:02:35,800 Speaker 1: Got to remember what's the purpose of an onboard computer 53 00:02:35,880 --> 00:02:41,840 Speaker 1: and the emission control system absolutely positively to maintain federal 54 00:02:41,880 --> 00:02:46,600 Speaker 1: emissions levels. That's the number one priority. Fuel economy, reliability, durability, 55 00:02:46,639 --> 00:02:49,760 Speaker 1: all that stuff. That's that's that's important, but it's secondary. 56 00:02:49,880 --> 00:02:54,880 Speaker 1: Everything is about emissions. So if something was askew, if 57 00:02:55,680 --> 00:02:58,280 Speaker 1: we you know, got the bad tank of gas, which 58 00:02:59,760 --> 00:03:01,320 Speaker 1: you know that seems to be the standby that a 59 00:03:01,320 --> 00:03:02,919 Speaker 1: lot of people still you know it must be a 60 00:03:02,960 --> 00:03:05,399 Speaker 1: bad tank against well whatever whatever gets you through the day. 61 00:03:05,440 --> 00:03:07,480 Speaker 1: But yeah, it could. You know, a car with an 62 00:03:07,480 --> 00:03:11,000 Speaker 1: incorrect ethanol blend would definitely cause a lean fault code 63 00:03:11,240 --> 00:03:14,640 Speaker 1: and make the light come on. So Sarah, to answer 64 00:03:14,720 --> 00:03:18,639 Speaker 1: the question, when that light is on, the absolute best 65 00:03:18,639 --> 00:03:22,760 Speaker 1: thing you can do is record the code. Either scan 66 00:03:22,840 --> 00:03:24,640 Speaker 1: it yourself with your own scanner, get out to a 67 00:03:24,680 --> 00:03:27,600 Speaker 1: parts house, let them at least record the code, write 68 00:03:27,639 --> 00:03:30,919 Speaker 1: it down, or get down to your local mechanic. And 69 00:03:31,240 --> 00:03:33,640 Speaker 1: you know, I'm not advocating that everybody stand there and 70 00:03:33,680 --> 00:03:35,640 Speaker 1: do something for free, but I think if you're a 71 00:03:35,680 --> 00:03:39,160 Speaker 1: regular customer and you've taken every nutbolt, washer, wiper, blade, 72 00:03:39,200 --> 00:03:42,360 Speaker 1: break job, oil change, maintenance and service and repair history 73 00:03:42,360 --> 00:03:44,880 Speaker 1: to this one mechanic, I think for them to give 74 00:03:44,920 --> 00:03:47,040 Speaker 1: you two minutes out in the driveway with a quick 75 00:03:47,080 --> 00:03:49,800 Speaker 1: tool to go, okay, yeah it's this particular fault, you 76 00:03:49,840 --> 00:03:51,640 Speaker 1: know what, will keep an eye on it. I don't 77 00:03:51,640 --> 00:03:53,840 Speaker 1: think that's such a bad idea for business and marketing. 78 00:03:53,880 --> 00:03:57,320 Speaker 1: I think that's actually a good idea. And then at 79 00:03:57,360 --> 00:04:01,520 Speaker 1: least you know. Then if the problem away in two 80 00:04:01,600 --> 00:04:04,000 Speaker 1: days or two weeks because you haven't been able to 81 00:04:04,000 --> 00:04:05,680 Speaker 1: get it in or maybe it's not in the budget, 82 00:04:05,720 --> 00:04:07,080 Speaker 1: or maybe you're trying to decide if you're going to 83 00:04:07,080 --> 00:04:09,880 Speaker 1: replace the vehicle, at least you know what it was 84 00:04:10,560 --> 00:04:14,320 Speaker 1: and the reason it goes away. For example, a catalytic 85 00:04:14,360 --> 00:04:17,560 Speaker 1: converter fault P zero four to twenty P zero four 86 00:04:17,680 --> 00:04:19,880 Speaker 1: twenty or a P zero four thirty. The more common 87 00:04:19,920 --> 00:04:24,839 Speaker 1: catalytic converter faults occur because there's a catalytic converter, which 88 00:04:24,920 --> 00:04:28,520 Speaker 1: is basically a device that through a catalytic a heat 89 00:04:28,640 --> 00:04:33,640 Speaker 1: related or a heat induced operation. Okay, we'll take and 90 00:04:33,680 --> 00:04:37,320 Speaker 1: reduce harmful pollutants out the tailpipe. There's a chemical reaction 91 00:04:37,480 --> 00:04:41,200 Speaker 1: going on there. And they look at oxygen content going 92 00:04:41,240 --> 00:04:45,159 Speaker 1: into the catalytic converter, they look at oxygen content coming 93 00:04:45,200 --> 00:04:48,520 Speaker 1: out of the catalytic converter. If the converter is doing 94 00:04:48,560 --> 00:04:52,360 Speaker 1: its proper job, if it is being efficient, it will 95 00:04:52,560 --> 00:04:56,960 Speaker 1: reduce emissions and it will change oxygen content to the 96 00:04:57,000 --> 00:05:00,600 Speaker 1: point that they will see a converter running at about 97 00:05:00,640 --> 00:05:04,719 Speaker 1: seventy to seventy five percent efficiency more on newer vehicles. Now, 98 00:05:05,800 --> 00:05:08,200 Speaker 1: if for some reason that converter is aging, if for 99 00:05:08,240 --> 00:05:10,719 Speaker 1: some reason that converter is struggling, that bad load of 100 00:05:10,720 --> 00:05:15,520 Speaker 1: fuel alters, how the two censors react, something causes that change, 101 00:05:15,600 --> 00:05:19,080 Speaker 1: and it goes to sixty eight percent, sixty nine percent, 102 00:05:19,040 --> 00:05:21,560 Speaker 1: and it's supposed to be seventy. That light's coming on 103 00:05:21,600 --> 00:05:24,000 Speaker 1: the next time it runs its test, and then you 104 00:05:24,080 --> 00:05:26,039 Speaker 1: go fill up, or you take it out for a ride. 105 00:05:26,160 --> 00:05:29,960 Speaker 1: Or the engine that stuck thermostat that was marginal, or 106 00:05:29,960 --> 00:05:33,600 Speaker 1: that thermostat was replaced by accident or as system maintenance 107 00:05:33,600 --> 00:05:37,120 Speaker 1: for whatever reason or whatever was done, and within a 108 00:05:37,160 --> 00:05:39,440 Speaker 1: short period of time, the next time that catalytic converter 109 00:05:39,520 --> 00:05:43,440 Speaker 1: self test or monitor as we call it runs and 110 00:05:43,480 --> 00:05:47,560 Speaker 1: now it passes, and it does that up to three times. 111 00:05:47,680 --> 00:05:50,840 Speaker 1: That light will go out. The code will still be there. 112 00:05:50,880 --> 00:05:53,240 Speaker 1: The code should still be there up to so many 113 00:05:53,240 --> 00:05:55,800 Speaker 1: turns of the key. It varies by manufacturery you're making 114 00:05:55,880 --> 00:05:59,680 Speaker 1: model thirty is a pretty good number, all right, but 115 00:06:00,080 --> 00:06:02,800 Speaker 1: there should be a fault recorded. I like to know 116 00:06:02,920 --> 00:06:05,159 Speaker 1: when I don't feel good. I like to know when 117 00:06:05,200 --> 00:06:07,200 Speaker 1: I get a dizzy spell. I like to know why 118 00:06:07,240 --> 00:06:09,479 Speaker 1: my blood pressure went up. And I like to do 119 00:06:09,520 --> 00:06:12,920 Speaker 1: the same thing with the car. And it just it's 120 00:06:13,080 --> 00:06:15,520 Speaker 1: just information. People are so afraid to go and get 121 00:06:15,800 --> 00:06:18,800 Speaker 1: a code scan because they think they're going to find 122 00:06:18,800 --> 00:06:20,360 Speaker 1: something they don't want to see. You already know it's 123 00:06:20,360 --> 00:06:22,000 Speaker 1: something you don't want to see the check engine lights on. 124 00:06:22,080 --> 00:06:24,600 Speaker 1: Nobody wants to fix the check engine light. It's going 125 00:06:24,640 --> 00:06:26,240 Speaker 1: to cost your money, but it's going to keep the 126 00:06:26,240 --> 00:06:29,799 Speaker 1: car reliable, and that's the whole point. So that random 127 00:06:29,920 --> 00:06:32,680 Speaker 1: light and you know, this is why I like to 128 00:06:32,680 --> 00:06:35,839 Speaker 1: go because that random light get the information while you can. 129 00:06:36,960 --> 00:06:38,360 Speaker 1: You know, I love the people that I don't want 130 00:06:38,400 --> 00:06:39,960 Speaker 1: to go get my car scanned because I don't want 131 00:06:39,960 --> 00:06:41,760 Speaker 1: to know what's going on. But in three weeks I'm 132 00:06:41,800 --> 00:06:44,039 Speaker 1: going on a cross country trip. Well yeah, that's great. 133 00:06:44,360 --> 00:06:46,120 Speaker 1: You know, let me know when the engine stops somewhere 134 00:06:46,160 --> 00:06:48,960 Speaker 1: south of Toledo, and you know, it could have been 135 00:06:48,960 --> 00:06:51,880 Speaker 1: prevented had we, you know, scanned the check engine light 136 00:06:52,240 --> 00:06:54,360 Speaker 1: and figured out that, you know, maybe we've got a 137 00:06:54,400 --> 00:06:57,760 Speaker 1: misfire event going on, or we've got a problem with 138 00:06:58,520 --> 00:07:02,360 Speaker 1: a critical engine sensor that's going to affect reliability and durability. 139 00:07:02,400 --> 00:07:05,440 Speaker 1: So you know, but that's why that check engine light 140 00:07:05,480 --> 00:07:07,760 Speaker 1: can go on and off. Every car goes through a 141 00:07:07,760 --> 00:07:11,520 Speaker 1: self test every time you turn the key. It's like you, Sarah, 142 00:07:11,560 --> 00:07:13,280 Speaker 1: when you get up in the morning, you go through 143 00:07:13,320 --> 00:07:15,800 Speaker 1: your routine. You have your coffee, you know, you take 144 00:07:15,840 --> 00:07:18,800 Speaker 1: a shower, you do whatever, you brush your teeth. That's 145 00:07:18,840 --> 00:07:21,560 Speaker 1: your self test. Car does the same thing and if 146 00:07:21,560 --> 00:07:23,960 Speaker 1: any one of those things fail, it starts to flag 147 00:07:24,000 --> 00:07:26,440 Speaker 1: it and if it fails enough times, the car will 148 00:07:26,440 --> 00:07:29,520 Speaker 1: turn on the check engine light, just like you. If 149 00:07:29,560 --> 00:07:33,040 Speaker 1: you don't get your coffee every morning, just guessing so, 150 00:07:33,360 --> 00:07:36,600 Speaker 1: but you get my point anyway, that's what that random 151 00:07:36,640 --> 00:07:40,680 Speaker 1: intermittent check engine light is all about, and it's an 152 00:07:40,680 --> 00:07:44,360 Speaker 1: important piece of information. Not knowing what that random check 153 00:07:44,400 --> 00:07:47,920 Speaker 1: engine light is what's creating that fault. In my mind, 154 00:07:48,800 --> 00:07:50,920 Speaker 1: that's just as bad as the person that says, well, 155 00:07:50,960 --> 00:07:54,200 Speaker 1: the check engine light came on, so I just disconnected 156 00:07:54,200 --> 00:07:57,080 Speaker 1: the battery to clear the code, because I'm sure it's 157 00:07:57,120 --> 00:08:00,840 Speaker 1: just a mistake. That's just as bad. Because when you 158 00:08:00,920 --> 00:08:03,040 Speaker 1: do that, and we should talk about that as long 159 00:08:03,080 --> 00:08:05,640 Speaker 1: as we're on the subject of check engine lights. When 160 00:08:05,680 --> 00:08:08,560 Speaker 1: you just clear the code, oh, even if you're going 161 00:08:08,600 --> 00:08:10,400 Speaker 1: with a scan tool and you capture the code it's 162 00:08:10,400 --> 00:08:13,200 Speaker 1: a P zero four to twenty or whatever it is, 163 00:08:13,440 --> 00:08:17,120 Speaker 1: and you just clear the code. Now you've just erased 164 00:08:17,800 --> 00:08:24,320 Speaker 1: something very critical called freeze frame. Freeze frame occurs on 165 00:08:24,440 --> 00:08:28,560 Speaker 1: all check edge and light occurrences anything since two thousand 166 00:08:28,600 --> 00:08:31,400 Speaker 1: and up. It's supposed to be there between ninety five 167 00:08:31,440 --> 00:08:33,559 Speaker 1: and two thousand maldi years, but they never really got 168 00:08:33,640 --> 00:08:36,240 Speaker 1: it right. It got better as time went on, but 169 00:08:36,840 --> 00:08:41,400 Speaker 1: freeze frame is a video snapshot of what certain sensors 170 00:08:41,440 --> 00:08:45,360 Speaker 1: were doing or seeing or reporting at the time of 171 00:08:45,400 --> 00:08:50,360 Speaker 1: the failure. It's kind of like if your blood pressure 172 00:08:50,400 --> 00:08:53,000 Speaker 1: spiked and you know you're able to take a freeze 173 00:08:53,000 --> 00:08:55,640 Speaker 1: frame snapshot, maybe you would be able to see that 174 00:08:55,679 --> 00:08:58,640 Speaker 1: you were climbing upstairs carrying three hundred pounds of something 175 00:08:59,240 --> 00:09:02,240 Speaker 1: in the hot sun without any shade protection, right, you 176 00:09:02,280 --> 00:09:05,040 Speaker 1: could see the exertion your body was going through. Well, 177 00:09:05,120 --> 00:09:07,080 Speaker 1: that's sort of what freeze frame is. It can see 178 00:09:07,080 --> 00:09:10,280 Speaker 1: how hard or how easy or how whatever the engine 179 00:09:10,360 --> 00:09:13,800 Speaker 1: was working in order to get the vehicle you know 180 00:09:14,360 --> 00:09:18,240 Speaker 1: where it wanted to go. So when you disconnect a battery, 181 00:09:18,280 --> 00:09:22,280 Speaker 1: when you just clear codes for no good reason, you 182 00:09:22,280 --> 00:09:24,440 Speaker 1: were erasing all that freeze frame data and now you 183 00:09:24,440 --> 00:09:25,840 Speaker 1: have to Yeah, you cleared the code, and then you 184 00:09:25,840 --> 00:09:27,839 Speaker 1: have to wait for the problem to happen again, and 185 00:09:27,880 --> 00:09:29,760 Speaker 1: then you got to capture it again. So it's it's 186 00:09:29,880 --> 00:09:32,400 Speaker 1: it's it's to me, that's just as bad as just 187 00:09:32,720 --> 00:09:34,680 Speaker 1: the check engine light came on and then it goes off. 188 00:09:34,840 --> 00:09:37,280 Speaker 1: I don't care what it is. A check engine light 189 00:09:37,440 --> 00:09:39,600 Speaker 1: is not there for an oil change, and check engine 190 00:09:39,679 --> 00:09:42,360 Speaker 1: light is not an indicator of services needed. A check 191 00:09:42,360 --> 00:09:45,960 Speaker 1: engine light is an indication of an internal system fault 192 00:09:46,240 --> 00:09:49,440 Speaker 1: in one of the emission control sensors or circuits. It 193 00:09:49,440 --> 00:09:51,800 Speaker 1: could be a big failure, it could be a little failure. 194 00:09:51,840 --> 00:09:53,160 Speaker 1: It could be a big problem. It could be a 195 00:09:53,200 --> 00:09:56,440 Speaker 1: little problem. You don't know until you scan it. Period done. 196 00:09:56,559 --> 00:09:59,600 Speaker 1: End of conversation eight five five five six oh nine 197 00:09:59,640 --> 00:10:01,600 Speaker 1: nine y zero zero, run a naming the car doctor. 198 00:10:01,600 --> 00:10:08,200 Speaker 1: I'll be back right after this once again. 199 00:10:08,480 --> 00:10:11,600 Speaker 2: Where vehicle not taking you where you want to go? 200 00:10:11,720 --> 00:10:14,200 Speaker 2: Well call Ron, He's the expert at making your vehicle 201 00:10:14,240 --> 00:10:16,360 Speaker 2: take you where you need it. Eight five five five 202 00:10:16,440 --> 00:10:19,760 Speaker 2: six zero nine nine zero zero And now back to Ron. 203 00:10:20,400 --> 00:10:23,640 Speaker 1: Let's uh oh, let's go to John waiting there very patiently. 204 00:10:23,720 --> 00:10:26,680 Speaker 1: Oh three impalla with a some sort of an intermittent 205 00:10:26,720 --> 00:10:28,839 Speaker 1: hard start problem. And John, welcome to the car doctor, sir. 206 00:10:28,880 --> 00:10:29,480 Speaker 1: What's going on? 207 00:10:30,240 --> 00:10:37,200 Speaker 4: Hey? Uh so an initial startup, it would start install 208 00:10:37,600 --> 00:10:40,160 Speaker 4: or it would it would run, and then maybe a 209 00:10:40,160 --> 00:10:43,520 Speaker 4: half hour later it would it would die. And sometimes 210 00:10:43,520 --> 00:10:46,880 Speaker 4: it would start right up, no problem. Other times there 211 00:10:46,920 --> 00:10:48,960 Speaker 4: were three cycles of the key and then I would 212 00:10:49,000 --> 00:10:51,560 Speaker 4: have to hold the gas pedal to the floor to 213 00:10:51,559 --> 00:10:55,480 Speaker 4: get it get it going again. Okay, So I pulled 214 00:10:55,520 --> 00:10:57,880 Speaker 4: some codes. I had a P zero one twenty eight 215 00:10:58,000 --> 00:11:03,640 Speaker 4: cold thermostat right P zero one two activity sensor. 216 00:11:03,800 --> 00:11:07,160 Speaker 1: Well here, back back up a second. The one twenty eight. Yep, 217 00:11:07,240 --> 00:11:11,079 Speaker 1: the one twenty eight is not necessarily a thermostat. Bye bye, 218 00:11:11,120 --> 00:11:15,160 Speaker 1: And I'm a stickler for this. I'm sorry bye. By definition, 219 00:11:15,360 --> 00:11:20,440 Speaker 1: it's it's it's thermostat rationality, it's it's it's not seeing 220 00:11:20,600 --> 00:11:24,720 Speaker 1: a correct or proper rate of rise once you start 221 00:11:24,720 --> 00:11:26,800 Speaker 1: the vehicle. You start the vehicle, it expects it to 222 00:11:26,880 --> 00:11:30,160 Speaker 1: hit proper temperature within so many minutes, and if it's 223 00:11:30,240 --> 00:11:33,200 Speaker 1: off by ten seconds, it goes boying and it sets 224 00:11:33,200 --> 00:11:37,080 Speaker 1: a one twenty eight. So it probably is a thermostat. 225 00:11:37,120 --> 00:11:40,560 Speaker 1: But just understand when you look at that, that's and 226 00:11:40,600 --> 00:11:43,520 Speaker 1: that that will not affect start unless this thing is 227 00:11:43,600 --> 00:11:47,199 Speaker 1: running stone cold all the time, all right, and we're 228 00:11:47,280 --> 00:11:49,200 Speaker 1: you know, we're we're constantly running so of Then my 229 00:11:49,240 --> 00:11:51,480 Speaker 1: first question for that would be what does engine temperature 230 00:11:51,520 --> 00:11:54,800 Speaker 1: come up to while you're driving? You know, do we 231 00:11:54,880 --> 00:11:58,520 Speaker 1: see do we see one seventy one eighty, you know, 232 00:11:58,559 --> 00:12:01,000 Speaker 1: instead of one ninety five two? And then you know, 233 00:12:01,040 --> 00:12:02,600 Speaker 1: I would put a thermostat in, but I don't think 234 00:12:02,600 --> 00:12:04,800 Speaker 1: that's your hard start. Go ahead, I'm sorry, I keep going. 235 00:12:06,520 --> 00:12:14,240 Speaker 4: But oxygen sensor low activity, and then an evapp vent 236 00:12:14,280 --> 00:12:17,040 Speaker 4: control of four forty six, and then a P eleven 237 00:12:17,160 --> 00:12:25,760 Speaker 4: eighty nine engine oil pressure circuit. So initially it felt 238 00:12:25,800 --> 00:12:27,640 Speaker 4: like it could have been like a crank sensor or 239 00:12:27,679 --> 00:12:29,920 Speaker 4: a fuel issue. I put a fuel pressure gauge on 240 00:12:30,000 --> 00:12:33,560 Speaker 4: it and I had perfect, perfect fuel pressure and it 241 00:12:33,840 --> 00:12:37,760 Speaker 4: actually died while I had the pressure gauge on and 242 00:12:37,760 --> 00:12:41,360 Speaker 4: it held pressure. So I kind of eliminated that. I 243 00:12:41,480 --> 00:12:46,120 Speaker 4: started manipulating the wire harness, started tapping on all the sensors. 244 00:12:47,000 --> 00:12:49,199 Speaker 4: I looked at the computer behind the air box. I 245 00:12:49,280 --> 00:12:53,360 Speaker 4: found a mouse mess with two like mice. I pulled 246 00:12:53,360 --> 00:12:57,480 Speaker 4: the connector off the PCM. All the connectors were cleaned, 247 00:12:57,559 --> 00:13:03,800 Speaker 4: no corrosion, and then I was kind of going down 248 00:13:03,840 --> 00:13:06,120 Speaker 4: the route with the crank sensor, and the car has 249 00:13:06,160 --> 00:13:11,160 Speaker 4: one hundred thousand miles on it, and I figured, let 250 00:13:11,160 --> 00:13:13,680 Speaker 4: me throw a crank sensor in it. And I didn't 251 00:13:13,679 --> 00:13:17,360 Speaker 4: think it was gonna solve it, but I did it anyways, 252 00:13:17,960 --> 00:13:26,720 Speaker 4: and the problem still persisted. Did a little research look 253 00:13:26,760 --> 00:13:29,080 Speaker 4: at I was looking at the ignition module and I 254 00:13:29,080 --> 00:13:32,760 Speaker 4: guess there's a lot of heat appreciated yep, that. 255 00:13:33,720 --> 00:13:38,600 Speaker 1: This has a separate CAM sensor too, right, John, Yes, okay, 256 00:13:39,440 --> 00:13:42,040 Speaker 1: all right, you know cam sensors. CAM sensors can cause 257 00:13:42,080 --> 00:13:44,640 Speaker 1: this full two. Let's do this. Let's let's talk about 258 00:13:44,760 --> 00:13:48,960 Speaker 1: let's talk about looking for what's good. Can we do that? Okay? 259 00:13:49,000 --> 00:13:50,640 Speaker 4: Well, I was just gonna let you know that a 260 00:13:50,679 --> 00:13:52,840 Speaker 4: friend of mine happened to have an ignition module for 261 00:13:52,920 --> 00:13:56,400 Speaker 4: thirty eight hundred and I borrowed it. They stuck it 262 00:13:56,480 --> 00:14:00,960 Speaker 4: in there and it solved the problem. Okay, my, I 263 00:14:00,960 --> 00:14:03,480 Speaker 4: guess my question to you is, how would you have 264 00:14:03,600 --> 00:14:15,640 Speaker 4: gone about diagnosing that ignition module. I would have. 265 00:14:15,080 --> 00:14:16,800 Speaker 1: Well, I would have I would have done I would 266 00:14:16,800 --> 00:14:19,040 Speaker 1: have done what you did, and I commend you. I 267 00:14:19,120 --> 00:14:20,480 Speaker 1: like I like you know. I would have looked at 268 00:14:20,480 --> 00:14:23,120 Speaker 1: fuel pressure. I would have put a plastic tube on 269 00:14:23,160 --> 00:14:25,440 Speaker 1: the fuel pressure regulator just to see as it's spitting 270 00:14:25,480 --> 00:14:26,040 Speaker 1: any fuel? 271 00:14:27,120 --> 00:14:27,280 Speaker 5: Huh? 272 00:14:27,360 --> 00:14:29,640 Speaker 1: All right? For the because you talked about a long 273 00:14:29,720 --> 00:14:33,160 Speaker 1: extended crank, right all right, And I would have I 274 00:14:33,160 --> 00:14:35,200 Speaker 1: would I would should have put a clear plastic tube 275 00:14:35,200 --> 00:14:37,400 Speaker 1: on that short piece of clear plastic tube on there, 276 00:14:37,480 --> 00:14:38,920 Speaker 1: just to see am I spitting any fuel? Is it 277 00:14:39,000 --> 00:14:41,600 Speaker 1: filling up with fuel? Uh? You know. Number one, I 278 00:14:41,640 --> 00:14:44,760 Speaker 1: would have done that. I would look at mass airflow 279 00:14:44,920 --> 00:14:48,160 Speaker 1: keon engine off grams per second. I should see, you know, 280 00:14:48,280 --> 00:14:51,360 Speaker 1: roughly four to four and a half grams or at 281 00:14:51,440 --> 00:14:53,040 Speaker 1: least now you'll know what to look for, you know, 282 00:14:53,200 --> 00:14:55,240 Speaker 1: just could I have a mass airflow problem? If you 283 00:14:55,240 --> 00:14:58,120 Speaker 1: have a mouse in the bottom left corner by the PCM, 284 00:14:58,200 --> 00:15:00,440 Speaker 1: did something crawl up into the air and take ducked? 285 00:15:00,520 --> 00:15:04,120 Speaker 1: And you know critters and cars, older cars, you know, 286 00:15:04,120 --> 00:15:06,560 Speaker 1: I always think about that, all right, So I would 287 00:15:06,560 --> 00:15:08,800 Speaker 1: have limited mass airflow. I believe on a thirty eight 288 00:15:08,840 --> 00:15:11,920 Speaker 1: hundred of that generation, if I had a mass airflow 289 00:15:12,000 --> 00:15:14,640 Speaker 1: or thought I had a mass airflow problem, I could 290 00:15:14,720 --> 00:15:17,080 Speaker 1: disconnect the mass airflow in the car would go into 291 00:15:17,160 --> 00:15:20,200 Speaker 1: default and run. So keep that in the back of 292 00:15:20,200 --> 00:15:22,360 Speaker 1: your head, and then yeah, I would have I would 293 00:15:22,360 --> 00:15:25,480 Speaker 1: have I would have tap tested the crank sensor very honestly. 294 00:15:26,120 --> 00:15:28,760 Speaker 1: You know, my, my, my twenty four inch three h 295 00:15:28,840 --> 00:15:31,320 Speaker 1: extension that's got the battle scars to prove it when 296 00:15:31,320 --> 00:15:35,600 Speaker 1: it catches the belt. Uh, I would have tap tested it. 297 00:15:35,640 --> 00:15:37,400 Speaker 1: Did you need a special tool to put that crank 298 00:15:37,440 --> 00:15:37,880 Speaker 1: sensor in? 299 00:15:39,760 --> 00:15:41,800 Speaker 4: No, I had to take the balancer off and then 300 00:15:41,800 --> 00:15:45,240 Speaker 4: there was a plastic cover over that. It's just two 301 00:15:45,320 --> 00:15:46,280 Speaker 4: bolts told in the Uh. 302 00:15:48,080 --> 00:15:50,320 Speaker 1: Yeah, there's there's so many versions of that crank sensor. 303 00:15:50,360 --> 00:15:53,040 Speaker 1: I never know which one I'm looking at. But then 304 00:15:53,040 --> 00:15:54,680 Speaker 1: I would have if I tap tested it, and then 305 00:15:54,680 --> 00:15:57,200 Speaker 1: I would have gotten down to uh, you know, I 306 00:15:57,200 --> 00:16:01,240 Speaker 1: would have either scoped it or I probably, honestly, if 307 00:16:01,280 --> 00:16:04,680 Speaker 1: I'm dealing with a twenty three year old vehicle, right, 308 00:16:04,800 --> 00:16:06,680 Speaker 1: you know, I would have put a spark tester on 309 00:16:06,760 --> 00:16:11,280 Speaker 1: the one of the spark plug wires, right, and you know, 310 00:16:11,800 --> 00:16:14,560 Speaker 1: what do I see? Do I do I not? Like 311 00:16:14,600 --> 00:16:16,440 Speaker 1: you know, we get we get into the arts here, 312 00:16:16,760 --> 00:16:20,880 Speaker 1: we talk about colors. What color was the spark? You know, 313 00:16:21,120 --> 00:16:23,360 Speaker 1: and then you know I would have sat down and said, hey, 314 00:16:23,480 --> 00:16:26,160 Speaker 1: do I you know it's twenty three years old. If 315 00:16:26,200 --> 00:16:30,760 Speaker 1: it's an original ignition module, right, while I can still 316 00:16:30,800 --> 00:16:34,440 Speaker 1: get one, I probably would have changed it. To be 317 00:16:34,560 --> 00:16:36,880 Speaker 1: very honest, I could have, you know, back back in 318 00:16:36,920 --> 00:16:41,600 Speaker 1: the day when you know, it was a different story 319 00:16:41,640 --> 00:16:44,080 Speaker 1: because we were doing ignition modules on those cars when 320 00:16:44,120 --> 00:16:46,680 Speaker 1: they had thirty thousand miles on them, right, and you 321 00:16:46,720 --> 00:16:48,480 Speaker 1: had to fight the battle of it's only got thirty 322 00:16:48,480 --> 00:16:52,040 Speaker 1: thousand miles on it. It can't be bit, you know. 323 00:16:52,080 --> 00:16:54,240 Speaker 1: And then we started to see a rash of those things. 324 00:16:55,200 --> 00:16:55,440 Speaker 4: You know. 325 00:16:55,680 --> 00:17:00,240 Speaker 1: I would also consider, did you replace the coil? No? 326 00:17:00,320 --> 00:17:02,560 Speaker 4: I did not replace. The car runs perfect now with 327 00:17:02,680 --> 00:17:03,440 Speaker 4: the new modules. 328 00:17:03,760 --> 00:17:07,199 Speaker 1: I would I would probably, I would probably replace the 329 00:17:07,240 --> 00:17:11,639 Speaker 1: coils just out of contention, because the coils sit on 330 00:17:11,640 --> 00:17:15,800 Speaker 1: top of the module, right right. I always wondered who 331 00:17:15,840 --> 00:17:18,960 Speaker 1: the engineer was that designed the electro power plant to 332 00:17:18,960 --> 00:17:22,840 Speaker 1: sit on top of the nuclear reactor. So if the 333 00:17:22,880 --> 00:17:28,280 Speaker 1: coil spiked the ground and it went into that ignition module, 334 00:17:28,359 --> 00:17:32,000 Speaker 1: you always wondered what it would do. So we we 335 00:17:32,160 --> 00:17:34,760 Speaker 1: ended up I learned this long time ago. Back in 336 00:17:34,800 --> 00:17:37,679 Speaker 1: the day, we would have those cars that seemed to 337 00:17:37,680 --> 00:17:41,200 Speaker 1: eat ignition modules, right, and then it became one of 338 00:17:41,280 --> 00:17:43,240 Speaker 1: two things we would we would and not. I'm not 339 00:17:43,320 --> 00:17:45,480 Speaker 1: saying your car is doing that. It's one hundred thousand 340 00:17:45,480 --> 00:17:49,320 Speaker 1: miles twenty three years old. But we learned from experience. 341 00:17:49,359 --> 00:17:52,800 Speaker 1: We would do ignition modules, I'm sorry, ignition coils, and 342 00:17:52,800 --> 00:17:54,760 Speaker 1: every once in a while you'd have a bad alternator 343 00:17:54,800 --> 00:17:58,160 Speaker 1: take it out, so you know things to look for. 344 00:17:58,520 --> 00:18:03,760 Speaker 1: You could probably those ignition coils out of Standard Motor products, 345 00:18:04,240 --> 00:18:06,680 Speaker 1: and Standard still makes a great coil and a great 346 00:18:06,680 --> 00:18:09,080 Speaker 1: module for those cars, so you might want to do that. 347 00:18:09,359 --> 00:18:11,919 Speaker 1: Enjoyed the conversation, John, You did it right, brother, and 348 00:18:12,000 --> 00:18:13,960 Speaker 1: you got it fixed. That's what counts. I'm ron An 349 00:18:14,040 --> 00:18:15,720 Speaker 1: Dye in the car doctor. I'll be back right after 350 00:18:15,760 --> 00:18:45,240 Speaker 1: this contract. Well, I guess it's my turn to twelk 351 00:18:45,240 --> 00:18:47,600 Speaker 1: eight five to five five six zero nine nine zero zero. 352 00:18:47,680 --> 00:18:50,320 Speaker 1: By the way, T shirt sales are booming. I guess 353 00:18:50,359 --> 00:18:52,840 Speaker 1: everybody must have bought Ariotomotive T shirts for mom for 354 00:18:52,960 --> 00:18:56,200 Speaker 1: Mother's Day. Now that can't be it. Maybe Father's Day 355 00:18:56,240 --> 00:18:58,240 Speaker 1: is coming up. But yeah, get out the card doctorshow 356 00:18:58,280 --> 00:19:01,119 Speaker 1: dot com if you're looking to click on the merchandise 357 00:19:01,119 --> 00:19:03,919 Speaker 1: button like everybody else. So we're doing well and don't forget. 358 00:19:04,119 --> 00:19:07,920 Speaker 1: Tomorrow fifteen Tacoma will appear in our YouTube feed around 359 00:19:07,920 --> 00:19:11,040 Speaker 1: three pm talking about that fifteenth Tacoma with the fuel 360 00:19:11,080 --> 00:19:13,600 Speaker 1: pump issue. I think it's one of the better videos. 361 00:19:13,640 --> 00:19:15,240 Speaker 1: We tried a couple of different things trying to show 362 00:19:15,240 --> 00:19:17,560 Speaker 1: you guys a little bit of variety of what we 363 00:19:17,600 --> 00:19:19,880 Speaker 1: looked at to fix that vehicle, and I think it's 364 00:19:19,920 --> 00:19:22,919 Speaker 1: going to do well. So that's tomorrow fifteenth, Tacoma up 365 00:19:22,960 --> 00:19:26,000 Speaker 1: on YouTube channel and we'll probably post it up to 366 00:19:26,040 --> 00:19:28,560 Speaker 1: Facebook two as well, although Facebook's getting a little funny 367 00:19:29,640 --> 00:19:31,760 Speaker 1: on how and what they allow. So but just know 368 00:19:31,800 --> 00:19:33,800 Speaker 1: that it's out on YouTube. Get out to our YouTube channel, 369 00:19:33,840 --> 00:19:36,160 Speaker 1: Ron and any and the Car Doctor in case you haven't. 370 00:19:36,680 --> 00:19:39,280 Speaker 1: Let's let's go to Joe in Pennsylvania. A lot of 371 00:19:39,280 --> 00:19:42,639 Speaker 1: Pennsylvania calls today. Ten Impalla. Hey Joe, how are you? 372 00:19:42,680 --> 00:19:43,520 Speaker 1: What can I do for you? 373 00:19:43,920 --> 00:19:48,199 Speaker 5: Yes, good afternoon, Yes sir, this Impala. It has a 374 00:19:48,240 --> 00:19:52,320 Speaker 5: different kind of console shifter than what's listed on YouTube. 375 00:19:52,320 --> 00:19:54,639 Speaker 5: And there's no real release button on you have to 376 00:19:54,680 --> 00:19:56,960 Speaker 5: play with and you have to push up and down 377 00:19:57,000 --> 00:20:00,400 Speaker 5: on the solenoids sometimes to get it out a park. 378 00:20:00,440 --> 00:20:03,840 Speaker 5: And what's bad about this run as Triple I refuses 379 00:20:03,920 --> 00:20:06,800 Speaker 5: to tow a car when it's stuck in park. Interesting, 380 00:20:07,400 --> 00:20:09,440 Speaker 5: they will not do it. They're afraid that they're gonna 381 00:20:09,760 --> 00:20:11,000 Speaker 5: damage the transmission. 382 00:20:11,320 --> 00:20:12,800 Speaker 1: Interesting, what do they do if? What do they do 383 00:20:12,800 --> 00:20:14,480 Speaker 1: if it's really stuck in park and you're stuck on 384 00:20:14,480 --> 00:20:15,120 Speaker 1: the side of the road. 385 00:20:15,280 --> 00:20:17,480 Speaker 5: It'll wait till the next day until somebody comes out 386 00:20:17,520 --> 00:20:20,960 Speaker 5: with a dolly or whatever. Yeah, it's crazy, it's ridiculous. 387 00:20:21,160 --> 00:20:23,760 Speaker 5: I'm sure you've come across it. Even the local dealer 388 00:20:23,840 --> 00:20:28,080 Speaker 5: here said he wouldn't do much for it because it's intermittent. 389 00:20:29,080 --> 00:20:31,119 Speaker 5: Well should I do buy a so annoyed for it? 390 00:20:31,200 --> 00:20:31,560 Speaker 5: Under there? 391 00:20:31,680 --> 00:20:33,879 Speaker 1: No, So let's let's let's talk about this. Let's and 392 00:20:33,960 --> 00:20:37,640 Speaker 1: I'm gonna make some assumptions of generality. Okay, so allow 393 00:20:37,760 --> 00:20:41,200 Speaker 1: me that. All right, So this is a This is 394 00:20:41,240 --> 00:20:44,080 Speaker 1: a ten in Pala with a three five right right, 395 00:20:44,359 --> 00:20:47,720 Speaker 1: and and the automatic trends won't come out of park exactly. 396 00:20:47,960 --> 00:20:50,880 Speaker 1: So when it when it fails, when it won't come 397 00:20:50,920 --> 00:20:53,680 Speaker 1: out of park, do you know if the break lights work? 398 00:20:55,359 --> 00:20:59,360 Speaker 5: Uh? They fixed it once. They put used parking and 399 00:20:59,520 --> 00:21:02,240 Speaker 5: they put other brake light switch on it too, I guess. 400 00:21:02,280 --> 00:21:05,200 Speaker 5: And see I bought it from a rebuildable place. 401 00:21:05,000 --> 00:21:09,400 Speaker 1: And it was because because that's critical. All right, if 402 00:21:09,680 --> 00:21:13,040 Speaker 1: the brake lights work, here's what happens. Right, Joe gets 403 00:21:13,040 --> 00:21:16,280 Speaker 1: in the car, He steps on the brake pedal, The 404 00:21:16,320 --> 00:21:20,400 Speaker 1: brake lights light up. Joe turns the key on the 405 00:21:20,400 --> 00:21:23,960 Speaker 1: the the brake lights switch completes and sends power up 406 00:21:24,000 --> 00:21:28,280 Speaker 1: to the body control module. All right, the body control 407 00:21:28,359 --> 00:21:32,399 Speaker 1: module sees the breake input request. It thinks Joe wants 408 00:21:32,440 --> 00:21:36,800 Speaker 1: to shift out of park because it sees it also 409 00:21:36,920 --> 00:21:39,919 Speaker 1: sees park on the on the trans side of life, 410 00:21:41,080 --> 00:21:44,360 Speaker 1: and it'll it releases the solenoid. It sends power out 411 00:21:44,359 --> 00:21:46,639 Speaker 1: on a separate wire. It sends wire. If you go 412 00:21:46,680 --> 00:21:49,080 Speaker 1: down to that shift solenoid, there's a dark green wire 413 00:21:49,119 --> 00:21:51,399 Speaker 1: with a white tracer. 414 00:21:51,840 --> 00:21:54,960 Speaker 5: And there's it's different than the ones on the YouTube video. 415 00:21:55,000 --> 00:21:57,760 Speaker 5: It's totally different. Even the dealer I went for a 416 00:21:57,800 --> 00:21:59,960 Speaker 5: technical service ball and it's totally different. 417 00:22:00,520 --> 00:22:02,120 Speaker 1: How's how's it totally different? 418 00:22:02,920 --> 00:22:05,040 Speaker 5: It doesn't have a release button on the side. 419 00:22:05,400 --> 00:22:08,399 Speaker 1: No, no, no, no, forget that. Look at wiring color? 420 00:22:09,200 --> 00:22:11,879 Speaker 1: All right? Do you are you taking this? Are you 421 00:22:11,880 --> 00:22:14,080 Speaker 1: taking this console apart on your own? Joe? 422 00:22:14,680 --> 00:22:16,440 Speaker 5: Yes? I took it off because. 423 00:22:16,680 --> 00:22:19,040 Speaker 1: Okay, so when you when you look at the shift 424 00:22:19,119 --> 00:22:23,320 Speaker 1: control solenoid, what color are the two wires at the solenoids? 425 00:22:24,359 --> 00:22:27,399 Speaker 5: Yes? I believe there's a green one there right, so. 426 00:22:27,600 --> 00:22:31,000 Speaker 1: The dark green wire with the white tracer, and listen, 427 00:22:31,680 --> 00:22:34,000 Speaker 1: learn how the circuit works when it's working. Will you 428 00:22:34,040 --> 00:22:34,840 Speaker 1: do me that favor? 429 00:22:36,200 --> 00:22:36,320 Speaker 4: So? 430 00:22:36,520 --> 00:22:38,320 Speaker 1: Yeah, win the. 431 00:22:38,280 --> 00:22:44,120 Speaker 5: Deal or they said the switch was working at the okay, great, 432 00:22:44,160 --> 00:22:46,640 Speaker 5: another problem. The break switch was working. 433 00:22:46,359 --> 00:22:48,960 Speaker 1: All right, so so but hear me out, all right, 434 00:22:49,400 --> 00:22:50,960 Speaker 1: I want you to put your foot on the brake, 435 00:22:51,080 --> 00:22:53,440 Speaker 1: turn the key on, and check voltage at that dark 436 00:22:53,480 --> 00:22:56,040 Speaker 1: green wire with the white trace. That should be bad 437 00:22:56,160 --> 00:23:00,239 Speaker 1: ory voltage. Then, with the meter still attached to that 438 00:23:00,359 --> 00:23:04,639 Speaker 1: dark green white wire, take your foot off the brake pedal. 439 00:23:04,680 --> 00:23:08,200 Speaker 1: You see battery voltage go to zero. That shows you 440 00:23:08,280 --> 00:23:13,120 Speaker 1: that's the working wire. You with me so far? Yes, okay, 441 00:23:13,320 --> 00:23:16,639 Speaker 1: when the problem happens, do we have power on that 442 00:23:16,760 --> 00:23:23,119 Speaker 1: dark green white? First question? Absolute, first question. If we 443 00:23:23,200 --> 00:23:26,120 Speaker 1: have power on that dark green white, we've just eliminated 444 00:23:26,160 --> 00:23:30,000 Speaker 1: seventy five percent of the circuit. Now we're down to 445 00:23:30,680 --> 00:23:35,199 Speaker 1: it's either the solenoid or the ground, which is the 446 00:23:35,200 --> 00:23:37,560 Speaker 1: other wire coming out of the solenoid. 447 00:23:38,080 --> 00:23:40,200 Speaker 5: Well, a couple of times I had to press in 448 00:23:40,240 --> 00:23:42,520 Speaker 5: on the solenoid itself to get it gone. 449 00:23:42,840 --> 00:23:45,680 Speaker 1: I understand that, but that's not testing it. I'm talking 450 00:23:45,760 --> 00:23:51,160 Speaker 1: about how to test it. Okay, are you able to test? 451 00:23:51,280 --> 00:23:52,040 Speaker 1: You have a vault meter? 452 00:23:52,280 --> 00:23:54,520 Speaker 5: Yes, I have many of them. Yeah, Okay. I mentioned 453 00:23:54,560 --> 00:23:59,440 Speaker 5: there's wiring faults and problems with wire routing, but. 454 00:24:01,359 --> 00:24:04,440 Speaker 1: Well but you have to catch it, Joe. You have 455 00:24:04,520 --> 00:24:08,320 Speaker 1: to catch it in the act. All right, it's intermittent. 456 00:24:09,040 --> 00:24:15,840 Speaker 1: Now you could you could run a new wire out 457 00:24:15,840 --> 00:24:17,840 Speaker 1: of the BCM. But what you want to do is 458 00:24:17,880 --> 00:24:19,720 Speaker 1: if you catch it in the act where you're stepping 459 00:24:19,760 --> 00:24:23,600 Speaker 1: on the brake pedal switch and you have no power 460 00:24:23,600 --> 00:24:27,320 Speaker 1: at that dark green white, trace it back. Get a 461 00:24:27,359 --> 00:24:30,159 Speaker 1: wiring diagram that dark green white goes direct to the 462 00:24:30,160 --> 00:24:34,760 Speaker 1: body computer. Okay, those wires have been known to break there. 463 00:24:34,880 --> 00:24:37,040 Speaker 1: They make a couple of tight turns as they come out. 464 00:24:37,480 --> 00:24:40,240 Speaker 1: They have been known to break internally, and sometimes replacement 465 00:24:40,280 --> 00:24:43,240 Speaker 1: of that wire does the trick. Sometimes this is a BCM, 466 00:24:43,680 --> 00:24:50,960 Speaker 1: the actual computer itself, all right, the dish right, Well, 467 00:24:50,960 --> 00:24:53,280 Speaker 1: it doesn't matter where it is. It's it's We can't 468 00:24:53,280 --> 00:24:56,720 Speaker 1: wish it was somewhere easy. Now, the other question I've 469 00:24:56,720 --> 00:24:58,879 Speaker 1: got is when they put a brake light switch in it, 470 00:25:00,000 --> 00:25:04,760 Speaker 1: I wonder if they did a break pedal position calibration. Uh. 471 00:25:05,760 --> 00:25:09,159 Speaker 1: They call it a b A Baker Paul Paul BPP, 472 00:25:09,880 --> 00:25:13,440 Speaker 1: a BPP calibration, and you need a scantl to do that. 473 00:25:13,600 --> 00:25:17,000 Speaker 1: And if they didn't do that, it will replicate the 474 00:25:17,040 --> 00:25:19,960 Speaker 1: same problem as a bad break light switch. The computer 475 00:25:20,119 --> 00:25:24,000 Speaker 1: needs to learn pedal position, and a new switch replacement 476 00:25:27,400 --> 00:25:27,920 Speaker 1: makes sense. 477 00:25:28,440 --> 00:25:31,359 Speaker 5: Well, so I can't just go bypassing it all the time. 478 00:25:31,400 --> 00:25:33,400 Speaker 5: That's gonna get old. It Well, it's. 479 00:25:33,320 --> 00:25:36,199 Speaker 1: Gonna get old. It's gonna get old very quickly. This 480 00:25:36,200 --> 00:25:38,520 Speaker 1: this isn't Listen, This isn't the hardest problem in the 481 00:25:38,520 --> 00:25:41,160 Speaker 1: world to solve. Somebody's got to sit down and understand 482 00:25:41,160 --> 00:25:43,960 Speaker 1: how the circuit works. And that's that's all I'm asking 483 00:25:44,000 --> 00:25:46,879 Speaker 1: you to do. All right. This is a simple solenoid. 484 00:25:46,920 --> 00:25:49,040 Speaker 1: It's a power in the ground. Power comes out of 485 00:25:49,040 --> 00:25:52,200 Speaker 1: the b CM. BCM looks at you know, break pedal 486 00:25:52,240 --> 00:25:55,520 Speaker 1: switch for input. It looks at park position because it 487 00:25:55,840 --> 00:25:58,639 Speaker 1: sees it sees park position. When you move the shifter, 488 00:25:59,320 --> 00:26:02,359 Speaker 1: there's an indicate on the dish right park, reverse, neutral, 489 00:26:02,440 --> 00:26:05,959 Speaker 1: drive and so on. Right, So that's because the shifter 490 00:26:06,160 --> 00:26:08,359 Speaker 1: is talking to the body computer, which is talking to 491 00:26:08,400 --> 00:26:11,199 Speaker 1: the instrument panel. What I'm trying to point out is 492 00:26:11,520 --> 00:26:13,879 Speaker 1: this isn't a straight shot where the brake pedal switch 493 00:26:14,280 --> 00:26:16,879 Speaker 1: moves that solenoid. The brake pedal switch puts input to 494 00:26:16,920 --> 00:26:19,800 Speaker 1: the BCM. The BCM looks at other conditions. If they're 495 00:26:19,800 --> 00:26:22,400 Speaker 1: all set. It sends voltage out that dark green white 496 00:26:22,400 --> 00:26:24,760 Speaker 1: over to the shift solenoid. The shift solenoid pulls in. 497 00:26:25,160 --> 00:26:27,280 Speaker 1: It's simple, It really is. 498 00:26:27,400 --> 00:26:30,680 Speaker 5: As Chevy dealer said, they wouldn't be able to fix it. 499 00:26:31,080 --> 00:26:36,520 Speaker 1: Listen so far, well, and that's true, okay to a degree. 500 00:26:36,880 --> 00:26:39,400 Speaker 1: Or somebody's got to take the bull by the horns 501 00:26:39,720 --> 00:26:42,879 Speaker 1: about how about this? How easy is it to get 502 00:26:42,920 --> 00:26:44,280 Speaker 1: to that dark green white wire. 503 00:26:46,000 --> 00:26:47,680 Speaker 5: Okay, I see it. 504 00:26:48,160 --> 00:26:50,000 Speaker 1: Go down to your local lotapart store, buy a one 505 00:26:50,119 --> 00:26:52,919 Speaker 1: ninety four bulb. Go go, get a little sidemark or 506 00:26:52,920 --> 00:26:57,240 Speaker 1: bulban socket. Cut the dark green white wire, put the 507 00:26:57,240 --> 00:26:59,680 Speaker 1: bulb in between. Cut the dark green white wire in 508 00:26:59,720 --> 00:27:01,959 Speaker 1: a play where you can easily solder it back together. 509 00:27:02,520 --> 00:27:05,120 Speaker 1: All right, Now, every time you step on the shift 510 00:27:05,200 --> 00:27:09,399 Speaker 1: or what's going to happen. If the system's working right, 511 00:27:10,200 --> 00:27:10,679 Speaker 1: it should light. 512 00:27:11,560 --> 00:27:12,640 Speaker 5: You should also hear it. 513 00:27:13,040 --> 00:27:13,919 Speaker 1: Well, you'll hear it. 514 00:27:13,960 --> 00:27:15,680 Speaker 5: They've had that system. 515 00:27:15,000 --> 00:27:20,600 Speaker 1: For early Joe, Joe, You're you're looking too far ahead. Okay, 516 00:27:21,480 --> 00:27:24,000 Speaker 1: I love you. You remember the card doctor Nation, But you're 517 00:27:24,000 --> 00:27:26,960 Speaker 1: looking too far ahead. I'm talking about diagnosing. You're talking 518 00:27:27,000 --> 00:27:30,320 Speaker 1: about expected results on something else. If that bulb lights 519 00:27:30,560 --> 00:27:32,800 Speaker 1: and you don't hear the click. Yeah, then you've either 520 00:27:32,800 --> 00:27:34,960 Speaker 1: got a ground or a solenoid issue. I'm trying to 521 00:27:34,960 --> 00:27:38,920 Speaker 1: tell you how to prove it. All right, If you 522 00:27:39,680 --> 00:27:42,560 Speaker 1: if you push on the brake pedal and it does 523 00:27:42,680 --> 00:27:46,560 Speaker 1: not light, where's the problem. 524 00:27:46,880 --> 00:27:51,080 Speaker 5: It's in their right switch or the. 525 00:27:51,000 --> 00:27:54,399 Speaker 1: Break light switch input because they didn't do a BBP calibration. 526 00:27:56,640 --> 00:27:57,520 Speaker 1: You get what I'm saying. 527 00:27:58,920 --> 00:28:00,840 Speaker 5: All Right, I guess I have to do all that 528 00:28:00,960 --> 00:28:03,320 Speaker 5: because I'm afraid I'm gonna get stuck permanently. 529 00:28:03,560 --> 00:28:04,680 Speaker 1: Yes, So. 530 00:28:06,320 --> 00:28:09,719 Speaker 5: All right, Joe, all right, you're. 531 00:28:09,119 --> 00:28:11,000 Speaker 1: Very welcome, sir. You'd be well. I'm running ady and 532 00:28:11,040 --> 00:28:32,480 Speaker 1: the car doctor. I'll be back right after this. Hey, 533 00:28:32,520 --> 00:28:34,359 Speaker 1: I want to go back and talk a little bit 534 00:28:34,359 --> 00:28:38,160 Speaker 1: about John from Connecticut with his three what was that 535 00:28:38,240 --> 00:28:40,680 Speaker 1: an three Chevy with the thirty hundred and the heart 536 00:28:40,720 --> 00:28:43,400 Speaker 1: start and it was a bad ignition module. Back in 537 00:28:43,440 --> 00:28:46,280 Speaker 1: the day we were doing, you know, because we were 538 00:28:46,280 --> 00:28:48,200 Speaker 1: a rush there at the end of that call. Back 539 00:28:48,200 --> 00:28:50,480 Speaker 1: in the day we were doing ignition modules. It was 540 00:28:50,480 --> 00:28:53,360 Speaker 1: always ignition modules and coils because as I was saying, 541 00:28:53,720 --> 00:28:57,960 Speaker 1: we always we found that a lot of times and 542 00:28:58,000 --> 00:28:59,800 Speaker 1: you would actually see it. You would take the coils 543 00:28:59,800 --> 00:29:01,560 Speaker 1: all and look at the bottom of the bakeel light 544 00:29:01,760 --> 00:29:07,160 Speaker 1: was cracked out. The ignition coil itself was spiking through 545 00:29:07,960 --> 00:29:10,880 Speaker 1: even without the epoxy or the bakel light being cracked 546 00:29:11,120 --> 00:29:13,440 Speaker 1: down into the module, down into ground. That it would 547 00:29:13,480 --> 00:29:17,080 Speaker 1: be like a voltage spike into the electronic component. And 548 00:29:17,120 --> 00:29:19,680 Speaker 1: it can only take so much of that. And over 549 00:29:19,800 --> 00:29:22,440 Speaker 1: time we would go through cars that had repeated ignition 550 00:29:22,560 --> 00:29:27,800 Speaker 1: module failures and we learned from you know, trial and error, 551 00:29:28,160 --> 00:29:29,880 Speaker 1: that it was it was a coil that was taking 552 00:29:29,920 --> 00:29:32,840 Speaker 1: out the module. We actually had problems with that system 553 00:29:33,040 --> 00:29:36,520 Speaker 1: again when all those cars were out there and you know, geez, 554 00:29:36,680 --> 00:29:39,719 Speaker 1: coils and modules sitting together like that. We actually had 555 00:29:39,720 --> 00:29:41,760 Speaker 1: more than a few cars where it was taking out 556 00:29:41,800 --> 00:29:45,920 Speaker 1: the actual engine PCM, the main engine computer. And we 557 00:29:45,920 --> 00:29:49,080 Speaker 1: were ended up doing quite a few where we put computers, 558 00:29:49,520 --> 00:29:52,880 Speaker 1: modules and ignition coils in cars in order to fix them. 559 00:29:52,920 --> 00:29:55,440 Speaker 1: And it wasn't a random throw parts at it fire 560 00:29:55,560 --> 00:29:58,480 Speaker 1: the parts ken and it was everything was fried as 561 00:29:58,520 --> 00:30:00,959 Speaker 1: a result of that ignition system. That was really a 562 00:30:01,040 --> 00:30:05,280 Speaker 1: bad design ignition system. That being said, I also go 563 00:30:05,440 --> 00:30:09,440 Speaker 1: back to we used to use Blue Streak from Standard 564 00:30:09,920 --> 00:30:13,040 Speaker 1: as the exclusive replacement because it worked better than the 565 00:30:13,080 --> 00:30:17,080 Speaker 1: OE standard had gone through with some redesign. And the 566 00:30:17,080 --> 00:30:18,840 Speaker 1: reason I know this is because I was involved in 567 00:30:18,880 --> 00:30:21,240 Speaker 1: the redesign back in the day. I was working with 568 00:30:21,320 --> 00:30:25,320 Speaker 1: Standard up close and personal at the time, and they 569 00:30:25,360 --> 00:30:29,600 Speaker 1: went through. They put better printed circuit board controls inside 570 00:30:29,640 --> 00:30:32,720 Speaker 1: their ignition modules, and they made a better than a 571 00:30:32,760 --> 00:30:36,200 Speaker 1: mouse better mouse trap ignition coil, so to speak. But 572 00:30:36,280 --> 00:30:38,720 Speaker 1: their Blue Streak stuff was top notch then it still 573 00:30:38,760 --> 00:30:42,040 Speaker 1: is today. Blue Streak was the quote unquote standard no 574 00:30:42,080 --> 00:30:46,320 Speaker 1: pun intended you know to use and look for. But John, 575 00:30:46,320 --> 00:30:48,560 Speaker 1: if you're still listening, by all means, I would I 576 00:30:48,600 --> 00:30:51,080 Speaker 1: would put I would replace the coil pack on that car, 577 00:30:51,640 --> 00:30:54,360 Speaker 1: and you know I wouldn't look back because that was 578 00:30:54,400 --> 00:30:56,640 Speaker 1: a common thing. It got to the point with those 579 00:30:56,680 --> 00:31:00,000 Speaker 1: cars where those the OE ignition coils and modules were 580 00:31:00,120 --> 00:31:03,800 Speaker 1: so bad we were replacing the amount of maintenance in 581 00:31:04,760 --> 00:31:07,000 Speaker 1: the fifty to seventy five thousand mile range because we 582 00:31:07,040 --> 00:31:08,520 Speaker 1: knew by the time it had one hundred on it, 583 00:31:08,520 --> 00:31:11,240 Speaker 1: and here you are at one hundred. As you said, 584 00:31:11,800 --> 00:31:13,920 Speaker 1: that coil was going to go bad and leave the 585 00:31:13,960 --> 00:31:19,120 Speaker 1: car stranded on occasional problems. We would also see a 586 00:31:19,160 --> 00:31:23,920 Speaker 1: bad alternator. We caught a few, not many, with a 587 00:31:23,960 --> 00:31:28,800 Speaker 1: bad diode that would alter. We actually caught it on 588 00:31:28,840 --> 00:31:32,280 Speaker 1: a scope twice. I remember the print out where we 589 00:31:32,400 --> 00:31:36,400 Speaker 1: caught the alternator diode would fail and it would put 590 00:31:36,440 --> 00:31:42,200 Speaker 1: out incorrect signal and cause the engine control module to 591 00:31:42,280 --> 00:31:45,880 Speaker 1: oversaturate coil dwell time, and that's what caused the coil 592 00:31:45,960 --> 00:31:48,680 Speaker 1: to fail. I mean, crazy stuff with those ignition systems, 593 00:31:48,720 --> 00:31:51,560 Speaker 1: but not something to take lightly. You never just put 594 00:31:51,560 --> 00:31:54,520 Speaker 1: an ignition module on one of those. You always did 595 00:31:54,560 --> 00:31:59,040 Speaker 1: coils and modules together. It just made sense. So, John, 596 00:31:59,080 --> 00:32:01,320 Speaker 1: if you're still listening to that, and like I said, 597 00:32:01,360 --> 00:32:05,400 Speaker 1: standard ignition products, you'll find them online. Just go research Standard. 598 00:32:05,520 --> 00:32:08,160 Speaker 1: I think it's s MP corp dot com and you 599 00:32:08,160 --> 00:32:10,120 Speaker 1: can get to the blue streak line and look it up. So, 600 00:32:10,320 --> 00:32:12,720 Speaker 1: but that's the way to go. Eight five five five 601 00:32:12,800 --> 00:32:15,000 Speaker 1: six nine nine zero zero. I'm running nady of the 602 00:32:15,000 --> 00:32:26,480 Speaker 1: card doctor. I'm back right after this. It's a second 603 00:32:27,600 --> 00:32:35,440 Speaker 1: hang on. So, uh, You've got an email in front 604 00:32:35,440 --> 00:32:39,160 Speaker 1: of me from a Tom down in Tennessee that writes 605 00:32:39,200 --> 00:32:41,640 Speaker 1: and he said, Hey, run, I heard your comments about 606 00:32:41,680 --> 00:32:46,600 Speaker 1: the no start intermittent falling out of the GMC Terrain 607 00:32:47,360 --> 00:32:49,720 Speaker 1: first Hour. If you tell me where it's on YouTube channel, 608 00:32:49,760 --> 00:32:51,920 Speaker 1: I can't find it. You know, I actually went looking 609 00:32:51,920 --> 00:32:55,480 Speaker 1: for it, Tom and it's it's it's before twenty two, 610 00:32:55,480 --> 00:32:57,760 Speaker 1: so I'm thinking it's about four years ago when we 611 00:32:57,800 --> 00:33:00,480 Speaker 1: first posted that. But the only thing I can tell 612 00:33:00,480 --> 00:33:02,000 Speaker 1: you is, and I'll try to find it, maybe put 613 00:33:02,080 --> 00:33:04,120 Speaker 1: up on our Facebook page. The only thing I can 614 00:33:04,160 --> 00:33:06,960 Speaker 1: tell you is that this was a problem where the 615 00:33:07,040 --> 00:33:09,240 Speaker 1: vehicle would shut off at random. You know, the worst 616 00:33:09,240 --> 00:33:11,880 Speaker 1: feeling in the world. You're driving down the road and 617 00:33:12,520 --> 00:33:16,920 Speaker 1: you just it just cut out. And what I discovered 618 00:33:17,280 --> 00:33:20,040 Speaker 1: through some pinpoint testing pretty much what you guys hear 619 00:33:20,120 --> 00:33:22,520 Speaker 1: me describe on the show about go to this wire, 620 00:33:22,800 --> 00:33:24,920 Speaker 1: check this wire, go to that wire, check that wire. 621 00:33:25,840 --> 00:33:27,840 Speaker 1: You know, it's no different in the shop. I'm doing 622 00:33:27,920 --> 00:33:31,080 Speaker 1: what I do here there and what I did for 623 00:33:31,120 --> 00:33:35,080 Speaker 1: that particular vehicle with this random no start, And I 624 00:33:35,120 --> 00:33:37,440 Speaker 1: realized I've got close to one hundred videos up on YouTube. 625 00:33:37,560 --> 00:33:39,160 Speaker 1: I think it's one of the first ones. Probably one 626 00:33:39,160 --> 00:33:42,400 Speaker 1: of the first one to fifteen would be my guess. 627 00:33:42,440 --> 00:33:44,760 Speaker 1: But what I ended up doing was I went wire 628 00:33:44,840 --> 00:33:49,200 Speaker 1: for wire, pin for pin, and I discovered where I 629 00:33:49,280 --> 00:33:51,719 Speaker 1: was losing voltage signal and traced it back to the 630 00:33:51,720 --> 00:33:54,920 Speaker 1: fuse box. And when I opened the fuse box up 631 00:33:55,280 --> 00:33:59,960 Speaker 1: the fuse box, it just it's just a series of strip, 632 00:34:00,200 --> 00:34:02,520 Speaker 1: copper strips, metal strips, whatever you want to call it. 633 00:34:02,880 --> 00:34:04,920 Speaker 1: And one of them had fractured one of the pins 634 00:34:04,920 --> 00:34:08,440 Speaker 1: that connect the fused circuit to power whatever circuit it 635 00:34:08,480 --> 00:34:10,799 Speaker 1: was powering. And every once in a while it hit 636 00:34:10,800 --> 00:34:13,600 Speaker 1: a bump and the contact would just go bang and 637 00:34:13,640 --> 00:34:16,680 Speaker 1: it would pop open like a small set of breaker 638 00:34:16,719 --> 00:34:19,480 Speaker 1: points almost, and you could see where it was rubbing 639 00:34:19,880 --> 00:34:23,120 Speaker 1: because it actually arcd and you could you could see 640 00:34:23,120 --> 00:34:25,279 Speaker 1: that the discoloration and the tips where the metal was 641 00:34:25,520 --> 00:34:27,960 Speaker 1: you know, power ground or not power ground, but power 642 00:34:28,000 --> 00:34:30,920 Speaker 1: power power boing boin and mooin wing. You know, applied 643 00:34:30,920 --> 00:34:34,680 Speaker 1: this release, applied this release and so on, and you know, 644 00:34:34,719 --> 00:34:36,319 Speaker 1: put a fuse box in the car and fixed it. 645 00:34:36,920 --> 00:34:38,319 Speaker 1: But of course I had to take it apart because 646 00:34:38,320 --> 00:34:40,880 Speaker 1: I wanted to know why I fixed it. You know, 647 00:34:40,960 --> 00:34:42,760 Speaker 1: I knew I had no I knew I had voltage 648 00:34:42,800 --> 00:34:44,560 Speaker 1: in nothing coming out. I knew it was the box, 649 00:34:44,600 --> 00:34:46,160 Speaker 1: but I wanted to know what it failed in the box. 650 00:34:46,360 --> 00:34:48,680 Speaker 1: You'll actually see it in the video, there's a good 651 00:34:48,719 --> 00:34:51,319 Speaker 1: shot of a magnifying glass if I recall correctly where 652 00:34:51,360 --> 00:34:53,919 Speaker 1: we show you the break. It's very very hard to see, 653 00:34:53,920 --> 00:34:56,080 Speaker 1: but Tom, that's what you're looking for. Like I said, 654 00:34:56,120 --> 00:34:58,759 Speaker 1: I'll try to put an exact date, you know, maybe 655 00:34:58,800 --> 00:35:01,640 Speaker 1: I can. I can repo stet up on Facebook, so 656 00:35:01,719 --> 00:35:03,759 Speaker 1: I'll do that as well. I'll do that as soon 657 00:35:03,760 --> 00:35:05,279 Speaker 1: as they get off air today, so it's there for 658 00:35:05,320 --> 00:35:08,120 Speaker 1: you guys, because it sounds like some people are interested. Anyway, 659 00:35:08,400 --> 00:35:10,040 Speaker 1: that's about it for today. Until the next time. I'm 660 00:35:10,040 --> 00:35:12,600 Speaker 1: brought an Aenie and the car doctor. Good mechanics aren't expensive, 661 00:35:12,719 --> 00:35:18,280 Speaker 1: they're priceless. See you
