Let me tell you. 28 00:01:28,080 --> 00:01:31,760 Speaker 5: Welcome to the radio home of Ron Andanian, the Car Doctor. 29 00:01:32,040 --> 00:01:33,360 Speaker 5: Since nineteen ninety one. 30 00:01:33,520 --> 00:01:35,360 Speaker 2: This is where car owners. 31 00:01:35,040 --> 00:01:39,440 Speaker 5: The world overturned to for their definitive opinion on automotive repair. 32 00:01:39,959 --> 00:01:42,760 Speaker 5: If your mechanics giving you a busy signal, pick. 33 00:01:42,640 --> 00:01:45,600 Speaker 2: Up the phone and call in. The garage door is 34 00:01:45,760 --> 00:01:47,760 Speaker 2: car open, but I am here to take your calls 35 00:01:48,080 --> 00:01:50,560 Speaker 2: at eight five five five six ninety nine hundred and 36 00:01:50,640 --> 00:01:52,840 Speaker 2: now pee. 37 00:01:54,120 --> 00:01:54,480 Speaker 5: Running. 38 00:01:55,200 --> 00:01:58,400 Speaker 2: I want to talk to you about, well, the perfect 39 00:01:58,440 --> 00:02:01,840 Speaker 2: storm of thegnosing an air conditioning problem, because this is 40 00:02:01,840 --> 00:02:03,640 Speaker 2: the one I always dread, and it's out there and 41 00:02:03,680 --> 00:02:06,120 Speaker 2: it happens every once in a while, and it's a 42 00:02:06,120 --> 00:02:10,400 Speaker 2: freak occurrence, but it happens, and it's real worlds and 43 00:02:10,440 --> 00:02:13,840 Speaker 2: it happened to me this week, and I this is 44 00:02:13,840 --> 00:02:16,080 Speaker 2: why I hate doing estimates. This is why when somebody says, hey, 45 00:02:16,160 --> 00:02:18,320 Speaker 2: Ron what's this gonna cost? I don't know. I can 46 00:02:18,360 --> 00:02:20,320 Speaker 2: give you a ballpark, but it goes out the window 47 00:02:20,360 --> 00:02:23,600 Speaker 2: as soon as I touch the car, because anything is possible. 48 00:02:25,240 --> 00:02:28,640 Speaker 2: Another repair shop brought us a twenty fifteen Jeep Grand 49 00:02:28,720 --> 00:02:33,959 Speaker 2: Cherokee that the ACE didn't work. So I know zero 50 00:02:34,040 --> 00:02:36,120 Speaker 2: about this car other than that it's a twenty fifteen 51 00:02:36,160 --> 00:02:40,480 Speaker 2: Jeep Grand Cherokee one hundred and thirty eight thousand miles silver. 52 00:02:41,440 --> 00:02:43,840 Speaker 2: Driver's door is kind of tight to open, which I'm 53 00:02:43,880 --> 00:02:46,480 Speaker 2: seeing a lot of. I'm not sure if anybody's got 54 00:02:47,000 --> 00:02:49,320 Speaker 2: a Jeep of that generation, I'd be curious what they're 55 00:02:49,360 --> 00:02:52,519 Speaker 2: experiencing because as these get older, that driver's door hinge 56 00:02:52,880 --> 00:02:56,359 Speaker 2: seems to bind or rust or stick something. There's something 57 00:02:56,400 --> 00:02:58,600 Speaker 2: weird going on there. This is the fourth one I've 58 00:02:58,639 --> 00:03:01,519 Speaker 2: seen in the last two years, so it's not it's 59 00:03:01,560 --> 00:03:03,480 Speaker 2: not you know, the one. The first one I saw. 60 00:03:03,520 --> 00:03:06,440 Speaker 2: The car was in an accident and supposedly not reassembled, right, 61 00:03:06,639 --> 00:03:09,280 Speaker 2: I could buy that, But three since that haven't been 62 00:03:09,280 --> 00:03:12,600 Speaker 2: an accident, so it's kind of weird. But I'm off subject. 63 00:03:14,400 --> 00:03:18,400 Speaker 2: The problem with air conditioning, to speak directly, is is 64 00:03:18,400 --> 00:03:21,280 Speaker 2: it animal, mineral or vegetable Is it chemical? Is it 65 00:03:21,280 --> 00:03:23,960 Speaker 2: out of refrigerant? Is it electrical? Is it not getting 66 00:03:23,960 --> 00:03:27,679 Speaker 2: proper signal? Is it mechanical? Did a component fail? And 67 00:03:27,919 --> 00:03:30,919 Speaker 2: and that's that's really what you're setting about to do 68 00:03:31,200 --> 00:03:33,639 Speaker 2: for somebody to say, hey, my AC isn't cooling? That 69 00:03:33,880 --> 00:03:38,440 Speaker 2: is that is the most difficult condition to diagnose. Where 70 00:03:38,440 --> 00:03:43,160 Speaker 2: do you start? I always do it like this. And 71 00:03:43,240 --> 00:03:45,400 Speaker 2: someone assured me this week that I am a very 72 00:03:45,440 --> 00:03:48,600 Speaker 2: sequential thought process human being, and I would have to 73 00:03:48,640 --> 00:03:50,920 Speaker 2: agree with that. They said, you're always ABC D and 74 00:03:51,000 --> 00:03:53,560 Speaker 2: E in. You don't do a to E and I don't. 75 00:03:53,720 --> 00:03:57,240 Speaker 2: I always go through the process. First thing I did, 76 00:03:57,280 --> 00:03:59,560 Speaker 2: I got in the car, check engine lights on. Okay, 77 00:04:00,160 --> 00:04:02,600 Speaker 2: quick show of hands. How many people are going to 78 00:04:02,640 --> 00:04:05,840 Speaker 2: scan this car for fault codes for an air conditioning problem? 79 00:04:06,440 --> 00:04:09,200 Speaker 2: I am? I did you know what? I found out? 80 00:04:09,680 --> 00:04:13,160 Speaker 2: The check engine lights on for nothing related to air conditioning. Well, 81 00:04:13,280 --> 00:04:15,920 Speaker 2: there was one chance there was a catalytic converter fault 82 00:04:15,920 --> 00:04:18,760 Speaker 2: code at P zero four thirty. There was an evaporative 83 00:04:18,760 --> 00:04:22,080 Speaker 2: emission's fault code a P zero four forty. And in 84 00:04:22,120 --> 00:04:24,440 Speaker 2: all my years, I've never seen a connection between those 85 00:04:24,440 --> 00:04:28,240 Speaker 2: two with each other or an air conditioning problem and 86 00:04:28,279 --> 00:04:30,800 Speaker 2: there was a P zero one twenty eight thermostat rate 87 00:04:30,839 --> 00:04:35,960 Speaker 2: of rise. Yeah, maybe I've seen overheat conditions cause air 88 00:04:36,000 --> 00:04:40,080 Speaker 2: conditioning to be commanded off. You know, what's the software strategy. 89 00:04:40,120 --> 00:04:43,120 Speaker 2: I don't memorize strategy unless it becomes a very very 90 00:04:43,160 --> 00:04:46,800 Speaker 2: common pattern failure, and then okay, I recognize it. So 91 00:04:47,160 --> 00:04:49,680 Speaker 2: one of the first things I did was I recorded 92 00:04:49,720 --> 00:04:52,479 Speaker 2: all the codes. I recorded, I reported everything, I sent 93 00:04:52,480 --> 00:04:54,920 Speaker 2: it out to a report. I captured the freeze frame. 94 00:04:54,960 --> 00:04:57,560 Speaker 2: I captured all the data that when all those problems occurred, 95 00:04:57,600 --> 00:05:01,479 Speaker 2: even though I'm just gathering data, testing and diagnostics. Cleared 96 00:05:01,520 --> 00:05:06,920 Speaker 2: the codes and no air conditioning operation. Okay, Next, hook 97 00:05:06,960 --> 00:05:09,360 Speaker 2: the set of gauges up. Hook the AC machine up. Actually, 98 00:05:09,360 --> 00:05:11,560 Speaker 2: now this is a twelve thirty four YF car, so 99 00:05:11,560 --> 00:05:14,880 Speaker 2: there's a very small amount of refrigerant in this This 100 00:05:14,960 --> 00:05:19,400 Speaker 2: took about twenty ounces of refrigerant, and in comparison on 101 00:05:19,680 --> 00:05:24,360 Speaker 2: a comparable one thirty four the older style refrigerant as 102 00:05:24,360 --> 00:05:27,359 Speaker 2: we've come to call it now equipped vehicle, that would 103 00:05:27,560 --> 00:05:30,920 Speaker 2: likely have been thirty to thirty six ounces of refrigerant. 104 00:05:31,000 --> 00:05:33,760 Speaker 2: So it's it's they've cut the capacity of the system 105 00:05:33,800 --> 00:05:39,080 Speaker 2: way down. Well, there was very little refrigerant there judging 106 00:05:39,160 --> 00:05:42,479 Speaker 2: by the gauges just about came up. They just showed 107 00:05:42,480 --> 00:05:48,480 Speaker 2: a whisper of pressure. Now, refrigerant loss is interesting, and 108 00:05:48,520 --> 00:05:50,920 Speaker 2: you do enough of these over the years, you kind 109 00:05:50,920 --> 00:05:54,400 Speaker 2: of see one interesting fact is and that is that 110 00:05:54,480 --> 00:05:58,440 Speaker 2: you can't trust anything that you're seeing. Is that is 111 00:05:58,480 --> 00:06:02,320 Speaker 2: that enough of a discharge that did it lose it? 112 00:06:03,000 --> 00:06:04,880 Speaker 2: And is it a leak? It's got to be a leak, 113 00:06:04,880 --> 00:06:09,119 Speaker 2: you're thinking to yourself, or is it just attrition over time? 114 00:06:09,160 --> 00:06:12,880 Speaker 2: Because this isn't eleven going on twelve year old vehicle. Again, 115 00:06:13,279 --> 00:06:15,520 Speaker 2: I know nothing of this vehicle. First time I've ever 116 00:06:15,560 --> 00:06:20,160 Speaker 2: seen it. Recovered what little refriger there was in there, 117 00:06:20,160 --> 00:06:22,040 Speaker 2: and I bet I didn't take two ounces out of this. 118 00:06:22,080 --> 00:06:24,880 Speaker 2: So right away I'm thinking leak. But it's always funny. 119 00:06:24,920 --> 00:06:27,159 Speaker 2: They always get down to this certain point and then 120 00:06:27,200 --> 00:06:30,320 Speaker 2: they stop leaking. And I've seen this with tires too. 121 00:06:30,360 --> 00:06:31,800 Speaker 2: You ever get a tire that leaks and it gets 122 00:06:31,839 --> 00:06:34,000 Speaker 2: down the twenty eight pounds and that's it. All of 123 00:06:34,040 --> 00:06:35,840 Speaker 2: a sudden, the leak is fixed. It never leaks, It 124 00:06:35,880 --> 00:06:37,920 Speaker 2: never leaks less than twenty eight, but it won't hold 125 00:06:37,960 --> 00:06:40,200 Speaker 2: more than twenty eight And you say why, And it 126 00:06:40,240 --> 00:06:42,480 Speaker 2: depends on the pressure leak and how it comes together 127 00:06:42,520 --> 00:06:47,039 Speaker 2: and folds over and seals itself. So I pulled vacuum. 128 00:06:47,120 --> 00:06:48,760 Speaker 2: I had no more refriger in it, and I pulled 129 00:06:48,760 --> 00:06:52,440 Speaker 2: a vacuum on the system and it pulled down into 130 00:06:52,480 --> 00:06:55,520 Speaker 2: a perfect, beautiful thirty inches of vacuum, pulled it into 131 00:06:55,560 --> 00:06:59,560 Speaker 2: a vacuum state deep and it stayed there for about 132 00:06:59,560 --> 00:07:01,680 Speaker 2: three and a halo a half hours. I just once 133 00:07:01,720 --> 00:07:03,760 Speaker 2: the machine reached the bottom, I just turned it off 134 00:07:04,320 --> 00:07:06,880 Speaker 2: and monitored it over the rest of the afternoon. Never 135 00:07:07,000 --> 00:07:11,840 Speaker 2: saw that vacuum gauge move even think about moving. I well, okay, 136 00:07:12,640 --> 00:07:16,840 Speaker 2: it holds vacuum. Called up talk to the repair shop. 137 00:07:16,880 --> 00:07:19,000 Speaker 2: I said, here's what I know. I said, I didn't 138 00:07:19,000 --> 00:07:21,080 Speaker 2: have any refrigerat. I've got a couple of fault codes 139 00:07:21,080 --> 00:07:23,320 Speaker 2: on this one hundred and thirty eight thousand mile older jeep. 140 00:07:23,840 --> 00:07:25,720 Speaker 2: You know, does the customer really want to fix it? 141 00:07:26,640 --> 00:07:28,640 Speaker 2: You know, we've got to ask that question. We're obligated. 142 00:07:28,680 --> 00:07:30,400 Speaker 2: It's eleven going on twelve years old. 143 00:07:31,240 --> 00:07:31,400 Speaker 4: You know. 144 00:07:31,520 --> 00:07:33,360 Speaker 2: Right now, all I know is it has no or 145 00:07:33,560 --> 00:07:36,720 Speaker 2: very little refrigerant charge left in it. You know, I've 146 00:07:36,760 --> 00:07:38,240 Speaker 2: got to blow a charge in it. I've got to 147 00:07:38,280 --> 00:07:40,040 Speaker 2: see what happens when I put a charge in it, 148 00:07:40,200 --> 00:07:43,280 Speaker 2: or I'm going to put CO two in it and 149 00:07:43,400 --> 00:07:46,200 Speaker 2: diagnose the leak. And the reason I say CO two 150 00:07:46,320 --> 00:07:49,120 Speaker 2: is because to blow a charge of twelve thirty four 151 00:07:49,240 --> 00:07:53,160 Speaker 2: yf into it gets expensive. It's an expensive refrigerant. It's 152 00:07:53,400 --> 00:07:56,760 Speaker 2: probably thirty five to forty percent higher in cost than 153 00:07:56,840 --> 00:08:00,920 Speaker 2: traditional one thirty four. So let's try doing the the 154 00:08:00,920 --> 00:08:06,080 Speaker 2: most effective, inexpensive way we can repair shops. Decision No, 155 00:08:06,240 --> 00:08:09,280 Speaker 2: blow a charge in it. Customer will see how long 156 00:08:09,320 --> 00:08:11,760 Speaker 2: it lasts. We'll see how long it goes on. They 157 00:08:11,760 --> 00:08:13,440 Speaker 2: know their customer, they know what they want to do. 158 00:08:14,280 --> 00:08:19,200 Speaker 2: I'm just taking orders and filling baskets, no problem. Blow 159 00:08:19,200 --> 00:08:22,760 Speaker 2: a charge in it. Hour later. Hey, the air conditioning 160 00:08:22,760 --> 00:08:25,600 Speaker 2: doesn't work in the jeep. Compressor doesn't turn on, but 161 00:08:25,640 --> 00:08:28,200 Speaker 2: it's got a charge in it. Ran around with a 162 00:08:28,200 --> 00:08:30,560 Speaker 2: black light real quick. Even though I didn't expect to 163 00:08:30,560 --> 00:08:33,840 Speaker 2: see anything, and I didn't see any leaks. I had 164 00:08:33,880 --> 00:08:36,800 Speaker 2: mentioned to them prior that the AC condenser. The condenser 165 00:08:36,880 --> 00:08:39,160 Speaker 2: is the piece that sits behind the grill in front 166 00:08:39,200 --> 00:08:42,080 Speaker 2: of the radiator, behind the grill in front of the radiator. 167 00:08:42,120 --> 00:08:44,360 Speaker 2: It takes all the road rash, all the crud, all 168 00:08:44,400 --> 00:08:46,640 Speaker 2: the junk from the road blowing up on it. You're 169 00:08:46,720 --> 00:08:48,720 Speaker 2: driving along at eighty eighty five on the Interstate, and 170 00:08:48,760 --> 00:08:50,880 Speaker 2: that you're right in the tail that eighteen wheel or 171 00:08:50,920 --> 00:08:53,360 Speaker 2: all that those little rocks are getting thrown into the 172 00:08:53,400 --> 00:08:56,160 Speaker 2: condenser as well as the windshielding and those of the car. 173 00:08:56,240 --> 00:09:00,160 Speaker 2: You know, I often think about that rock chips only 174 00:09:00,200 --> 00:09:02,120 Speaker 2: happened when you're doing one hundred miles an hour or more. 175 00:09:02,200 --> 00:09:05,040 Speaker 2: But that's a hot rod story for another day. So 176 00:09:06,280 --> 00:09:08,840 Speaker 2: what do you want to do? Well, diagnose why the 177 00:09:08,840 --> 00:09:11,480 Speaker 2: AC doesn't come on? Oki Doki. So I let it 178 00:09:11,480 --> 00:09:13,160 Speaker 2: sit overnight. It was late in the day at that point. 179 00:09:13,200 --> 00:09:17,559 Speaker 2: Came in the next morning and listen, how complicated you 180 00:09:17,600 --> 00:09:19,760 Speaker 2: want to make this? Started the truck up, Bang, check 181 00:09:19,760 --> 00:09:24,080 Speaker 2: engine lights back on again. All right, let's see what's there. 182 00:09:24,960 --> 00:09:28,000 Speaker 2: EVAP fault. It failed EVAP overnight because the EVAPP ran 183 00:09:28,040 --> 00:09:30,600 Speaker 2: overnight when the vehicle was off. It's a key on 184 00:09:30,679 --> 00:09:34,760 Speaker 2: engine off monitor for EVAP and it set an EVAP code. 185 00:09:34,880 --> 00:09:37,560 Speaker 2: Don't care, it's got nothing to do with my air conditioning. 186 00:09:38,480 --> 00:09:40,160 Speaker 2: And I said, you know what, Let's go right to 187 00:09:40,200 --> 00:09:41,920 Speaker 2: the source. While I had the scan tool looked up 188 00:09:41,960 --> 00:09:45,199 Speaker 2: looking at codes, I went into the body computer and 189 00:09:45,240 --> 00:09:48,000 Speaker 2: the engine controller and I turned the AC on them. 190 00:09:48,000 --> 00:09:51,160 Speaker 2: I could look right on the scan tool, AC request off, 191 00:09:51,880 --> 00:09:56,280 Speaker 2: bank hit the button AC request on. Okay, so I've 192 00:09:56,280 --> 00:09:58,520 Speaker 2: got the command. The command is coming through the computer. 193 00:09:58,559 --> 00:10:01,120 Speaker 2: It's replaying it back to the scan tool. I can 194 00:10:01,120 --> 00:10:03,600 Speaker 2: see that the button works, the dash works. I tried 195 00:10:03,679 --> 00:10:06,400 Speaker 2: functional test. There's a functional test where you can manually 196 00:10:06,440 --> 00:10:09,680 Speaker 2: overwrite everything and turn the AC compressor on. Nada, nothing. 197 00:10:09,800 --> 00:10:14,199 Speaker 2: ZIP got out a wiring diagram just for giggles, and 198 00:10:14,240 --> 00:10:16,600 Speaker 2: I saw that everything ran through the power distribution center, 199 00:10:16,600 --> 00:10:18,400 Speaker 2: which I kind of expected. But I said, you know, 200 00:10:19,120 --> 00:10:22,240 Speaker 2: it's a simple two wire compressor, twelve vaults in ground. 201 00:10:23,679 --> 00:10:28,160 Speaker 2: So I got out the tongue in cheek, he says, 202 00:10:28,240 --> 00:10:33,400 Speaker 2: with a smile on his face. Most singularly expensive piece 203 00:10:33,400 --> 00:10:36,080 Speaker 2: of diagnostic equipment I have in the shop, and it's 204 00:10:36,120 --> 00:10:41,600 Speaker 2: about twenty eight years old. It's a seven inch round 205 00:10:41,960 --> 00:10:46,040 Speaker 2: style headlamp. That's it off of an old actually I 206 00:10:46,040 --> 00:10:49,600 Speaker 2: think it's off of an old Chevelle. And I measured it. 207 00:10:49,600 --> 00:10:51,439 Speaker 2: It pulls about a seven and a half to eight 208 00:10:51,480 --> 00:10:54,320 Speaker 2: amp blow depending upon the day. And it's great as 209 00:10:54,360 --> 00:10:57,960 Speaker 2: a load substitution. Disconnected the AC compressor. Wired it in 210 00:10:58,040 --> 00:11:01,079 Speaker 2: as nice as you plead, please with some some wires 211 00:11:01,080 --> 00:11:03,800 Speaker 2: and connect clips that I keep around the shop. Turn 212 00:11:03,840 --> 00:11:07,439 Speaker 2: the AC on. Bang, headlight turns on. Okay, you got 213 00:11:07,440 --> 00:11:12,120 Speaker 2: a bad compressor. I so here's a system that was empty. 214 00:11:12,600 --> 00:11:15,560 Speaker 2: Here's a system that needs a compressor. And I said, 215 00:11:15,600 --> 00:11:18,839 Speaker 2: you know, it's been twenty four hours. Let me go 216 00:11:18,920 --> 00:11:20,920 Speaker 2: down and look at that bottom of that condenser again. 217 00:11:20,920 --> 00:11:22,280 Speaker 2: And I get down. I turn off the lights in 218 00:11:22,320 --> 00:11:24,439 Speaker 2: the shop. Well, actually I turned off the lights in 219 00:11:24,480 --> 00:11:27,160 Speaker 2: the shop. Surprised Danny because Danny was doing something. Oh sorry, 220 00:11:27,200 --> 00:11:29,240 Speaker 2: I'm turning off the lights. Danny was in the dark 221 00:11:29,280 --> 00:11:33,480 Speaker 2: there for a minute and got down, glasses on, looking 222 00:11:33,600 --> 00:11:36,520 Speaker 2: through with a black light, bottom of the condenser shows green. 223 00:11:36,600 --> 00:11:37,000 Speaker 4: Dye. 224 00:11:37,280 --> 00:11:40,440 Speaker 2: Okay, turn the lights back on. Got Danny back to work, 225 00:11:41,320 --> 00:11:44,200 Speaker 2: called up the shop. Hey, guess what. I have good 226 00:11:44,200 --> 00:11:46,520 Speaker 2: news and I have bad news. The good news is 227 00:11:46,520 --> 00:11:48,520 Speaker 2: I know why the AC doesn't work. The bad news 228 00:11:48,559 --> 00:11:50,240 Speaker 2: is it's the compressor. Oh and by the way, the 229 00:11:50,280 --> 00:11:54,520 Speaker 2: condenser's leaking, so it needs a compressor. A condenser, probably 230 00:11:54,600 --> 00:11:58,240 Speaker 2: a catalytic converter, some sort of evap diagnosis, and the 231 00:11:58,240 --> 00:12:01,840 Speaker 2: thermostat the twenty fifteen jeep of one hundred and thirty 232 00:12:01,840 --> 00:12:06,320 Speaker 2: eight thousand miles probably needs seven or eight grand worth 233 00:12:06,360 --> 00:12:08,240 Speaker 2: of work by the time you start agging it all up. 234 00:12:09,640 --> 00:12:11,520 Speaker 2: But that's not what I'm there for. I'm there to 235 00:12:11,600 --> 00:12:14,120 Speaker 2: just diagnose the AC, not pass judgment. Now, Tom and 236 00:12:14,120 --> 00:12:15,800 Speaker 2: I were talking about this before the show today and 237 00:12:15,800 --> 00:12:17,360 Speaker 2: Tom said, well, isn't it time to just get a 238 00:12:17,360 --> 00:12:19,040 Speaker 2: new vehicle? And I said, you know, Tom, I don't 239 00:12:19,040 --> 00:12:20,640 Speaker 2: know the answer to that question. I don't know what 240 00:12:20,720 --> 00:12:23,800 Speaker 2: sort of service and maintenance was done to that question. Now, 241 00:12:23,840 --> 00:12:26,640 Speaker 2: Tom Ray, my executive producer, chief cook and bottle washer 242 00:12:26,640 --> 00:12:29,600 Speaker 2: that pays attention to me, he brought back the correct question. 243 00:12:29,679 --> 00:12:31,800 Speaker 2: He said, what's next, what if? And what's next? And 244 00:12:31,880 --> 00:12:35,480 Speaker 2: I said, right, I said, but what maintenance has been done? 245 00:12:35,720 --> 00:12:39,240 Speaker 2: And that's what I want to know. The point is, 246 00:12:40,280 --> 00:12:43,480 Speaker 2: estimates are tough to write. An estimate is nothing better 247 00:12:43,520 --> 00:12:46,920 Speaker 2: than an educated guess, especially in the world of AC. 248 00:12:47,040 --> 00:12:50,679 Speaker 2: But in the majority of times it's an educated guess. 249 00:12:51,480 --> 00:12:55,359 Speaker 2: I think an estimate really helped prepare you the customer 250 00:12:56,160 --> 00:12:58,800 Speaker 2: you know, grit your teeth and showed determination. Charlie Brown, 251 00:12:58,880 --> 00:13:01,280 Speaker 2: can you get through the ex of this repair or not? 252 00:13:02,640 --> 00:13:03,920 Speaker 2: I'm not sure what they're going to do to fix 253 00:13:03,960 --> 00:13:05,280 Speaker 2: the jeep. I'm not sure if they're going to fix 254 00:13:05,320 --> 00:13:08,400 Speaker 2: the jeep. The shop took it back. They paid me 255 00:13:08,440 --> 00:13:11,640 Speaker 2: for my diagnosis, and we'll see it may come back 256 00:13:11,679 --> 00:13:13,640 Speaker 2: next week so we can recharge the system for them. 257 00:13:13,679 --> 00:13:16,800 Speaker 2: They don't have a twelve thirty four YF machine and 258 00:13:17,679 --> 00:13:23,200 Speaker 2: time marches on estimates air conditioning. Boy, sometimes the two 259 00:13:23,360 --> 00:13:26,080 Speaker 2: just don't seem to go together. Eight five five five 260 00:13:26,200 --> 00:13:28,520 Speaker 2: six oh nine nine zero zero. I'm running Indy in 261 00:13:28,520 --> 00:13:30,320 Speaker 2: the car doctor. I'll be back right after this. 262 00:13:37,280 --> 00:13:40,360 Speaker 6: Where you're vehicle not taking you where you want to go, 263 00:13:40,480 --> 00:13:42,960 Speaker 6: Well call Ron. He's the expert at making your vehicle 264 00:13:43,000 --> 00:13:45,120 Speaker 6: take you where you need it. Eight five five five 265 00:13:45,200 --> 00:13:48,520 Speaker 6: six zero nine nine zero zero. And now back to Ron. 266 00:13:48,760 --> 00:13:51,120 Speaker 2: Hey, let's go down to Tennessee and talk to Emmett. Emmett, 267 00:13:51,120 --> 00:13:52,680 Speaker 2: what's going on? Running the Indie in the car Doctor 268 00:13:52,720 --> 00:13:53,440 Speaker 2: at your servicer? 269 00:13:54,240 --> 00:13:56,719 Speaker 3: Okay, I've got a note here and I'm gonna read 270 00:13:56,760 --> 00:13:58,920 Speaker 3: it to you, and then if I leave something out 271 00:13:59,640 --> 00:14:03,000 Speaker 3: that's for you to tell me what to do. First off, 272 00:14:03,400 --> 00:14:07,640 Speaker 3: I put a big hammer near the toolbox and I 273 00:14:07,679 --> 00:14:12,280 Speaker 3: call it my attitude adjustment tool. But anyway, it's a 274 00:14:12,360 --> 00:14:17,960 Speaker 3: twenty sixteen Kia Soul plus two liter in a direct injection, 275 00:14:18,240 --> 00:14:23,000 Speaker 3: no turbo check engine like it popped on. I took 276 00:14:23,000 --> 00:14:28,400 Speaker 3: it to AutoZone. They diagnosed it as a P zero 277 00:14:28,520 --> 00:14:33,600 Speaker 3: four to four zero, I think the first time canister. 278 00:14:34,760 --> 00:14:40,280 Speaker 3: Let's see here the per Solinois valve. They said. I 279 00:14:40,280 --> 00:14:42,160 Speaker 3: didn't want to leave without a part, so I bought 280 00:14:42,160 --> 00:14:45,200 Speaker 3: the part. Then when I got home, I went online 281 00:14:45,240 --> 00:14:48,640 Speaker 3: to doctor University Google and found out what was going on. 282 00:14:49,480 --> 00:14:52,920 Speaker 3: Did the check with the twelve oll that either you 283 00:14:53,200 --> 00:14:56,080 Speaker 3: apply twelve to it, it closes it you whatever, And 284 00:14:56,640 --> 00:15:00,320 Speaker 3: yeah it worked, so really I took the old one out, 285 00:15:01,240 --> 00:15:05,720 Speaker 3: checked it and I believe it was working. But I 286 00:15:05,760 --> 00:15:11,840 Speaker 3: replaced it. Anyway, I at that time went to a 287 00:15:11,920 --> 00:15:18,480 Speaker 3: TVC valve. It leaked, suck and blow test leaked about 288 00:15:18,480 --> 00:15:23,320 Speaker 3: eighty about held eighty percent. You could tell a smaller leak, 289 00:15:23,680 --> 00:15:26,440 Speaker 3: just a small leak. So I replaced it. Before I 290 00:15:26,480 --> 00:15:29,720 Speaker 3: put it in. That one checked tight suck and blow. 291 00:15:29,800 --> 00:15:33,960 Speaker 3: Everything was fine. I go about my business I run 292 00:15:33,960 --> 00:15:41,280 Speaker 3: Exxon fuel standard octane regular gas and four or five tanks. 293 00:15:41,720 --> 00:15:46,320 Speaker 3: The light pops on a P four four two. So 294 00:15:46,440 --> 00:15:48,760 Speaker 3: at this point I take it to a friend who's 295 00:15:49,040 --> 00:15:52,240 Speaker 3: a good mechanic. They do all kinds of checks, smoke 296 00:15:52,320 --> 00:15:56,720 Speaker 3: checked it. Everything was fine, and then we sat down 297 00:15:56,800 --> 00:16:00,960 Speaker 3: scratched our heads. What should we do next? So I 298 00:16:01,000 --> 00:16:03,640 Speaker 3: looked around. He's a drag racer, and he says, you know, 299 00:16:04,280 --> 00:16:06,400 Speaker 3: I've thought about this a lot since you told me 300 00:16:06,440 --> 00:16:10,280 Speaker 3: about it. I'm wondering if it's manner is the fuel 301 00:16:10,400 --> 00:16:15,840 Speaker 3: vapor pressures are affecting that the computers and they're throwing codes. 302 00:16:15,880 --> 00:16:19,000 Speaker 3: Because when I fuel up and have a tank of fuel, 303 00:16:20,920 --> 00:16:23,120 Speaker 3: I'll get up to thirty one to thirty two miles 304 00:16:23,160 --> 00:16:26,520 Speaker 3: to gallon. I drive ten miles to the house, it's 305 00:16:26,600 --> 00:16:29,720 Speaker 3: dropped one or two miles. The next morning that's still 306 00:16:30,440 --> 00:16:33,480 Speaker 3: that's say thirty one miles to gallon. I go twenty 307 00:16:33,520 --> 00:16:35,880 Speaker 3: miles down the road and it'll drop down to twenty 308 00:16:35,920 --> 00:16:39,560 Speaker 3: eight three, twenty eight five and slowly over the tank 309 00:16:39,640 --> 00:16:43,360 Speaker 3: of that fuel increase up to thirty thirty one miles 310 00:16:43,400 --> 00:16:43,920 Speaker 3: to the gallon. 311 00:16:44,720 --> 00:16:49,840 Speaker 2: EMMETT stop there in I don't know in more years 312 00:16:49,880 --> 00:16:52,479 Speaker 2: than I care to remember. I've never seen a correlation 313 00:16:52,600 --> 00:16:57,680 Speaker 2: of EBAP system leaks against fuel economy. So we can 314 00:16:57,720 --> 00:17:00,920 Speaker 2: go down that road, but with all respect, we're gonna 315 00:17:00,920 --> 00:17:07,040 Speaker 2: go into analysis paralysis. Right, So let's talk about evaporative emissions, 316 00:17:07,720 --> 00:17:10,280 Speaker 2: all right, because you're you're in the neighborhood of evaporative 317 00:17:10,280 --> 00:17:14,840 Speaker 2: emissions and system failures. Do you understand what evap emissions 318 00:17:14,840 --> 00:17:16,560 Speaker 2: is about? And I don't say that to embarrass you, 319 00:17:16,600 --> 00:17:18,320 Speaker 2: I say that as a general question. Do you do 320 00:17:18,359 --> 00:17:21,440 Speaker 2: you know what they're looking at, or testing or concerned 321 00:17:21,440 --> 00:17:24,560 Speaker 2: about with regards to the evaporative emission systems of a vehicle. 322 00:17:25,480 --> 00:17:28,440 Speaker 3: Well, my understanding is you're you're picking up that they're 323 00:17:28,480 --> 00:17:30,879 Speaker 3: directing the fuels up to the intake manifold so they 324 00:17:30,920 --> 00:17:31,639 Speaker 3: get reburned. 325 00:17:32,640 --> 00:17:34,760 Speaker 2: Well, that's part of it. And it's not that they're 326 00:17:34,760 --> 00:17:38,679 Speaker 2: putting fuel. They're putting fuel vapor, all right, vapor. But 327 00:17:38,880 --> 00:17:43,440 Speaker 2: the idea is this, take a take a gallon gas can, right, 328 00:17:44,119 --> 00:17:45,920 Speaker 2: and you know you're going down to the local story, 329 00:17:46,000 --> 00:17:47,960 Speaker 2: local gas station. You fill up your gas can with 330 00:17:48,000 --> 00:17:49,280 Speaker 2: a gallon of fuel, and you put it in the 331 00:17:49,359 --> 00:17:54,200 Speaker 2: driveway in the hot sun, sealed up what's gonna happen 332 00:17:54,240 --> 00:17:54,479 Speaker 2: to it? 333 00:17:55,520 --> 00:17:58,639 Speaker 3: The tank is gonna it's either gonna blow the cork 334 00:17:58,720 --> 00:18:01,240 Speaker 3: off or you can see the tank expand. 335 00:18:00,920 --> 00:18:05,160 Speaker 2: Right, it's going to bulge. Right, So aren't automobiles really 336 00:18:05,200 --> 00:18:09,560 Speaker 2: like that gas can? You think about it? Right? So 337 00:18:09,600 --> 00:18:12,920 Speaker 2: we've got to have a way to vent pressure from 338 00:18:13,000 --> 00:18:15,320 Speaker 2: the gas tank out to the atmosphere. But if we 339 00:18:15,400 --> 00:18:18,520 Speaker 2: did that by traditional methods, well in the old days, 340 00:18:18,520 --> 00:18:20,159 Speaker 2: we would have violated the Clean Air Act. I'm not 341 00:18:20,200 --> 00:18:24,120 Speaker 2: sure anymore, but the idea is we would be violating 342 00:18:24,160 --> 00:18:27,800 Speaker 2: the Clean Air Act of putting harmful emissions into the atmosphere. 343 00:18:28,640 --> 00:18:33,960 Speaker 2: So the onboard vehicle has a charcoal canister that, at 344 00:18:33,960 --> 00:18:38,440 Speaker 2: the proper time, based on tank pressure and fuel temperature, 345 00:18:39,040 --> 00:18:42,320 Speaker 2: will open up a vent valve and allow fumes to 346 00:18:42,400 --> 00:18:47,000 Speaker 2: transfer out to the atmosphere via the charcoal canister. You're 347 00:18:47,000 --> 00:18:50,119 Speaker 2: with me, Yeah, all right? You sit tight. When I 348 00:18:50,160 --> 00:18:51,760 Speaker 2: come back, we're going to do a deeper dive and 349 00:18:51,800 --> 00:18:54,280 Speaker 2: talk a little bit more we'bout evapp. But this really 350 00:18:54,280 --> 00:18:56,400 Speaker 2: comes back to I want you to understand how evapp 351 00:18:56,520 --> 00:18:59,560 Speaker 2: works before we talk about the potential cures and some 352 00:18:59,600 --> 00:19:01,760 Speaker 2: of the quick checks you can do here so don't 353 00:19:01,760 --> 00:19:03,640 Speaker 2: go anywhere I'm running any of the car. Doctor. We'll 354 00:19:03,640 --> 00:19:06,440 Speaker 2: be back with EMMITTT from Tennessee and is sixteen kia 355 00:19:06,840 --> 00:19:41,080 Speaker 2: right after this. Yay yay from the city streets to 356 00:19:41,200 --> 00:19:46,040 Speaker 2: the open road. If your run needs help, run, we'll 357 00:19:46,160 --> 00:19:47,120 Speaker 2: keep you rolling. 358 00:19:47,240 --> 00:19:47,440 Speaker 6: Right. 359 00:19:48,760 --> 00:19:53,159 Speaker 1: Here's a card, doctor, Doctor car invist. 360 00:19:56,040 --> 00:20:01,720 Speaker 2: Emmitt. You there, sir, Emmitt, Yeah, oh, there you go. 361 00:20:02,240 --> 00:20:04,720 Speaker 2: So when we took the pause, we were talking about evap, right, 362 00:20:04,760 --> 00:20:07,600 Speaker 2: We're talking about the dangers of a sealed gas tank 363 00:20:07,640 --> 00:20:09,639 Speaker 2: and how it could rupture and expand, and so we 364 00:20:09,720 --> 00:20:12,480 Speaker 2: have to find a way to vent those fumes. Right, yeah, 365 00:20:12,800 --> 00:20:16,159 Speaker 2: So on a car, there's two devices. There's a purge 366 00:20:16,240 --> 00:20:18,960 Speaker 2: valve and there's a vent valve. Purge valve is in 367 00:20:19,000 --> 00:20:21,840 Speaker 2: the front, vent valve is in the back. When they 368 00:20:21,880 --> 00:20:23,960 Speaker 2: want to, they'll open up the vent valve. They'll run, 369 00:20:24,119 --> 00:20:26,800 Speaker 2: allow fumes to vent out of the tank to reduce 370 00:20:26,880 --> 00:20:31,520 Speaker 2: pressure through the charcoal canister to clean things up, and 371 00:20:31,600 --> 00:20:34,560 Speaker 2: that cuts back on pressure and prevents the tank from bulging, exploding, 372 00:20:34,560 --> 00:20:38,320 Speaker 2: et cetera, et cetera, et cetera. Right when the engine, 373 00:20:38,320 --> 00:20:42,920 Speaker 2: when the engine is running at select times, they will 374 00:20:42,920 --> 00:20:45,480 Speaker 2: open up the purge valve, they'll close the vent, they'll 375 00:20:45,520 --> 00:20:47,960 Speaker 2: open the purge. Sometimes they open the vent to allow 376 00:20:48,000 --> 00:20:51,160 Speaker 2: air to pull through, all right, and they will take 377 00:20:51,200 --> 00:20:54,879 Speaker 2: those fumes and scavenge or vacuum out the canister if 378 00:20:54,920 --> 00:20:56,879 Speaker 2: they feel it's got too much fumes in it, so 379 00:20:56,920 --> 00:20:59,000 Speaker 2: they don't overload it and it gets oversaturated. 380 00:20:59,119 --> 00:21:01,240 Speaker 4: You're with me, yes, sir. You know. 381 00:21:01,359 --> 00:21:03,600 Speaker 2: Think of it as if you live in a house 382 00:21:03,600 --> 00:21:04,840 Speaker 2: with a front door and a back door. 383 00:21:05,680 --> 00:21:05,920 Speaker 1: Yep. 384 00:21:06,080 --> 00:21:08,200 Speaker 2: If the air is stuff, you open up the front door. 385 00:21:08,200 --> 00:21:09,800 Speaker 2: If you want air to pass through, you open up 386 00:21:09,840 --> 00:21:11,920 Speaker 2: the front door and the back door. Front door is 387 00:21:11,920 --> 00:21:15,360 Speaker 2: the purge valve. Back door is the vent valve. Depends 388 00:21:15,359 --> 00:21:19,840 Speaker 2: on the condition, depends on whether temperature, a bunch of factors. Now, 389 00:21:20,080 --> 00:21:22,520 Speaker 2: the one thing we haven't added to our evaporative system 390 00:21:22,600 --> 00:21:25,520 Speaker 2: yet is and the question you got to be asking yourself, 391 00:21:25,680 --> 00:21:27,240 Speaker 2: how do they know when it's the right time to 392 00:21:27,280 --> 00:21:27,840 Speaker 2: do anything? 393 00:21:28,960 --> 00:21:29,200 Speaker 4: Right? 394 00:21:30,119 --> 00:21:33,600 Speaker 2: Yeah, So they add something called an FTP, a fuel 395 00:21:33,920 --> 00:21:39,320 Speaker 2: tank pressure sensor. All systems have it, and they look 396 00:21:39,359 --> 00:21:42,960 Speaker 2: at voltage. It's a variable resistor. It's a variable voltage signal. 397 00:21:43,720 --> 00:21:47,160 Speaker 2: Typically at rest keon, engine off, you'll see about two 398 00:21:47,160 --> 00:21:49,240 Speaker 2: and a half volts out of most of them, and 399 00:21:49,240 --> 00:21:51,520 Speaker 2: then as it pulls it into a vacuum state, it'll 400 00:21:51,520 --> 00:21:53,280 Speaker 2: go down, and as it goes into a pressure state, 401 00:21:53,320 --> 00:21:56,320 Speaker 2: it'll go up. All Right. The reason they have it 402 00:21:56,359 --> 00:21:58,040 Speaker 2: at two and a half volts is that's kind of 403 00:21:58,080 --> 00:21:59,560 Speaker 2: middle of the road, right, If it's a zero to 404 00:21:59,600 --> 00:22:02,560 Speaker 2: five volt scale, two and a half vaults is middle 405 00:22:03,560 --> 00:22:08,880 Speaker 2: easy to remember, right, So at select times they're gonna 406 00:22:08,920 --> 00:22:11,360 Speaker 2: pull they're going to try and vent the canister. At 407 00:22:11,400 --> 00:22:13,440 Speaker 2: certain times they're going to try and pull fumes into 408 00:22:13,440 --> 00:22:16,639 Speaker 2: the engine. A four to four You started out with 409 00:22:16,680 --> 00:22:19,000 Speaker 2: a four to forty folt code, right, P zero four 410 00:22:19,000 --> 00:22:24,000 Speaker 2: to forty, which is a general EVAP failure. Change the part, 411 00:22:24,160 --> 00:22:27,320 Speaker 2: Now you've got a four to forty two? Right? 412 00:22:28,240 --> 00:22:28,520 Speaker 3: Right? 413 00:22:28,720 --> 00:22:32,800 Speaker 2: Do you still have the old part? I believe, Do 414 00:22:33,480 --> 00:22:36,879 Speaker 2: me a favor, put it back on the car. Okay, 415 00:22:37,119 --> 00:22:41,919 Speaker 2: you changed the purge valve, right, yeah, okay, do me 416 00:22:41,920 --> 00:22:44,680 Speaker 2: a favor, put it back on the car. Let's let's see. 417 00:22:44,800 --> 00:22:46,199 Speaker 2: The first thing I want to know is does the 418 00:22:46,200 --> 00:22:51,840 Speaker 2: P zero four to forty come back because the code changed? 419 00:22:51,960 --> 00:22:55,479 Speaker 2: It changed when you changed the part. Did firing the 420 00:22:55,520 --> 00:22:58,080 Speaker 2: parts can and create the issue? And now it's going 421 00:22:58,160 --> 00:23:02,160 Speaker 2: to take you down a dark path, right and make 422 00:23:02,240 --> 00:23:04,520 Speaker 2: you think there's more problems here than there actually is. 423 00:23:04,840 --> 00:23:07,600 Speaker 2: Once you get that original purge valve back on the car. 424 00:23:08,880 --> 00:23:10,920 Speaker 2: The purge valve we're talking about is in the front 425 00:23:11,000 --> 00:23:13,320 Speaker 2: up by the engine, correct, correct? 426 00:23:13,359 --> 00:23:13,720 Speaker 4: All right? 427 00:23:14,720 --> 00:23:20,239 Speaker 2: With I want you to electrically disconnect the purge and 428 00:23:20,280 --> 00:23:22,240 Speaker 2: you know the rubber hose that led to the back 429 00:23:22,280 --> 00:23:26,399 Speaker 2: of the car. Yes, that's the hose that the fumes 430 00:23:26,480 --> 00:23:30,320 Speaker 2: came from out of the canister. Starting to make sense, Yes, 431 00:23:30,440 --> 00:23:37,800 Speaker 2: all right, with that valve electrically disconnected and the engine running, 432 00:23:40,040 --> 00:23:43,560 Speaker 2: should we have vacuum at that inlet side to the 433 00:23:43,560 --> 00:23:45,800 Speaker 2: purge valve where the hose is disconnected? What do you think? 434 00:23:47,240 --> 00:23:48,920 Speaker 3: No, you wouldn't have any right. 435 00:23:49,400 --> 00:23:51,280 Speaker 2: When will we have vacuum there. 436 00:23:52,400 --> 00:23:54,320 Speaker 3: When you connect the hose and the valve opens? 437 00:23:54,400 --> 00:23:58,520 Speaker 2: No, when you electrically connect the valve electrically Okay, right? 438 00:23:59,000 --> 00:24:01,359 Speaker 2: And I said it like that for a very specific reason. 439 00:24:01,720 --> 00:24:09,960 Speaker 2: That valve is commanded open, capiche. Yes, So, so if 440 00:24:10,200 --> 00:24:12,879 Speaker 2: we start the car and I do this with a 441 00:24:12,920 --> 00:24:15,560 Speaker 2: rubber glove on, I I wet the end of my 442 00:24:15,600 --> 00:24:17,800 Speaker 2: finger and I'll just stick it over the end of 443 00:24:17,800 --> 00:24:19,560 Speaker 2: the purge valve with the engine running, and I'll do 444 00:24:19,600 --> 00:24:21,240 Speaker 2: this when the engine's cold. I'll do this when the 445 00:24:21,240 --> 00:24:23,560 Speaker 2: engine's warm. I want to see if it changes with temperature. 446 00:24:24,240 --> 00:24:26,800 Speaker 2: And if my finger is sucked towards that purge valve 447 00:24:26,880 --> 00:24:31,000 Speaker 2: in the least little way. What does that mean? 448 00:24:33,760 --> 00:24:37,560 Speaker 3: That is the valve is open and you're pulling the 449 00:24:37,680 --> 00:24:38,760 Speaker 3: vapors into the engine. 450 00:24:38,920 --> 00:24:42,240 Speaker 2: Right, that valve is leaking. Right if it's electrically disconnected, 451 00:24:42,280 --> 00:24:45,000 Speaker 2: there's no way that valve can make can or should 452 00:24:45,000 --> 00:24:46,119 Speaker 2: mechanically be open. 453 00:24:46,400 --> 00:24:48,359 Speaker 3: Right, Okay, I see what you're saying. 454 00:24:48,680 --> 00:24:52,040 Speaker 2: Right, the front door is leaking. The wifes can plain 455 00:24:52,119 --> 00:24:56,000 Speaker 2: and emmett it's cold in here, close the door, right, 456 00:24:56,920 --> 00:25:00,320 Speaker 2: So there's there's no way that's that's working. Now, if 457 00:25:00,359 --> 00:25:02,600 Speaker 2: you go put your replacement perge valve on and you 458 00:25:02,600 --> 00:25:05,359 Speaker 2: get a different fault code, you know what that means. 459 00:25:06,920 --> 00:25:10,760 Speaker 2: The new perge valve is no good. You know it's 460 00:25:10,840 --> 00:25:14,280 Speaker 2: it's it's we're dealing with two different things here because 461 00:25:14,320 --> 00:25:17,440 Speaker 2: the parts canon got fired. So I want to baseline 462 00:25:17,480 --> 00:25:20,640 Speaker 2: this car. I want to diagnose. A fault code isn't 463 00:25:20,640 --> 00:25:25,280 Speaker 2: a diagnosis. A fault code is gathering information and I'm 464 00:25:25,320 --> 00:25:28,159 Speaker 2: stressing that for you and everybody else listening today because 465 00:25:28,200 --> 00:25:31,120 Speaker 2: that's the reality of it. Nowhere in a P zero 466 00:25:31,280 --> 00:25:34,440 Speaker 2: four forty two or four forty or four fifty six 467 00:25:34,600 --> 00:25:36,600 Speaker 2: or any other fault code, does it go You've got 468 00:25:36,600 --> 00:25:40,399 Speaker 2: this code, change that part. There's multiple steps to consider. 469 00:25:40,480 --> 00:25:45,280 Speaker 2: There's multiple ways that that code gets triggered. All right, Okay, 470 00:25:45,640 --> 00:25:49,720 Speaker 2: Now to do a deeper dive into EVAPP. Let's say 471 00:25:49,920 --> 00:25:53,800 Speaker 2: that perge valve was connected, and it's electrically connected, and 472 00:25:54,359 --> 00:26:00,520 Speaker 2: it wasn't being commanded on right right. So if I 473 00:26:00,520 --> 00:26:02,080 Speaker 2: had a scan tool and I looked at the fuel 474 00:26:02,080 --> 00:26:05,000 Speaker 2: tank pressure sensor and it said two and a half volts, 475 00:26:05,760 --> 00:26:07,320 Speaker 2: and all of a sudden, I'm looking at it and 476 00:26:07,320 --> 00:26:10,400 Speaker 2: I see it go to two four two three two 477 00:26:10,440 --> 00:26:13,240 Speaker 2: point two one point eight. Wait a minute, I'm not 478 00:26:13,280 --> 00:26:15,560 Speaker 2: commanding the purge valve on. What does the computer think? 479 00:26:17,000 --> 00:26:20,560 Speaker 2: Incorrect purge flow? Right? 480 00:26:21,560 --> 00:26:21,840 Speaker 4: Right? 481 00:26:21,880 --> 00:26:24,960 Speaker 2: It's not electrically commanding it on, but it knows because 482 00:26:24,960 --> 00:26:27,040 Speaker 2: it looks at FTP it says, hey, wait a minute, 483 00:26:27,119 --> 00:26:31,880 Speaker 2: how's the voltage changing? And that's why and that's why 484 00:26:31,920 --> 00:26:36,600 Speaker 2: we test, because could I have a shorted FTP sensor? Sure? 485 00:26:37,520 --> 00:26:41,439 Speaker 2: Could I have a bad purge valve? Sure you know 486 00:26:41,560 --> 00:26:44,040 Speaker 2: there's there's a couple of scenarios. Could the ground wire 487 00:26:44,080 --> 00:26:46,760 Speaker 2: for the purge valve be shorted against something metallic and 488 00:26:46,800 --> 00:26:49,240 Speaker 2: closing it and pulling the purge on if there's power 489 00:26:49,280 --> 00:26:53,360 Speaker 2: to it all the time. Sure you see the danger 490 00:26:53,400 --> 00:26:54,560 Speaker 2: in just swapping parts. 491 00:26:55,760 --> 00:26:59,000 Speaker 3: Well, I'm a full believer the swapping parts. And that's 492 00:26:59,040 --> 00:27:02,960 Speaker 3: what bothers me about technicians. A lot of them read 493 00:27:03,040 --> 00:27:04,959 Speaker 3: the codes and then they go and see what the 494 00:27:04,960 --> 00:27:08,200 Speaker 3: parts are recommended or a possibility yep, and they start 495 00:27:08,280 --> 00:27:11,000 Speaker 3: changing parts. They don't go further and diagnostic. 496 00:27:11,240 --> 00:27:13,400 Speaker 2: Right, that's right, absolutely. 497 00:27:14,920 --> 00:27:18,200 Speaker 3: And I'm not I don't have a scanner. Nope, I'm 498 00:27:18,200 --> 00:27:21,920 Speaker 3: not a brainiac or a computer guru. But like I say, 499 00:27:21,960 --> 00:27:24,800 Speaker 3: I try to figure out why it's happening. Then if 500 00:27:24,840 --> 00:27:27,360 Speaker 3: you figure that out, then you can correct it. 501 00:27:27,480 --> 00:27:30,080 Speaker 2: Right. But that's what I want you to do. First. 502 00:27:30,160 --> 00:27:31,960 Speaker 2: I want you to go look at purge. I want 503 00:27:32,000 --> 00:27:34,199 Speaker 2: you to test it the way I described it, and 504 00:27:34,280 --> 00:27:38,200 Speaker 2: if that purge is working, leave it alone. Then we'll 505 00:27:38,200 --> 00:27:40,760 Speaker 2: have to talk further. I want to see what code 506 00:27:40,760 --> 00:27:42,800 Speaker 2: comes back. I want to see what this develops into. 507 00:27:43,160 --> 00:27:45,640 Speaker 2: This could be a bad Hey, can the front door 508 00:27:45,680 --> 00:27:48,160 Speaker 2: of your house leak? Can? 509 00:27:48,280 --> 00:27:48,480 Speaker 4: Can? 510 00:27:48,560 --> 00:27:50,200 Speaker 2: Can the back door of your house leak? 511 00:27:51,960 --> 00:27:52,200 Speaker 4: Right? 512 00:27:52,320 --> 00:27:54,639 Speaker 2: You know there's there's just a bunch of scenarios. I 513 00:27:54,640 --> 00:27:58,040 Speaker 2: want to see what fault codes are truly occurring? All right? 514 00:27:58,080 --> 00:27:59,160 Speaker 2: How many miles are on this. 515 00:27:59,160 --> 00:28:02,520 Speaker 3: Kiya ninety ninety three thousand. 516 00:28:02,680 --> 00:28:04,720 Speaker 2: Well, the honest answer is it's all bad. But let's 517 00:28:04,720 --> 00:28:08,920 Speaker 2: try and diagnose it anyway. All right, but do those 518 00:28:09,000 --> 00:28:10,800 Speaker 2: changes for me. Call me back next week or the 519 00:28:10,800 --> 00:28:12,680 Speaker 2: week after. Let me know what happens. 520 00:28:12,920 --> 00:28:18,720 Speaker 3: Yes, I got one question real quick, velvelean, restore, and protect. 521 00:28:18,760 --> 00:28:21,000 Speaker 3: Have you had any experience with that oil? No? 522 00:28:21,280 --> 00:28:24,000 Speaker 2: But you know, just because I haven't seen it doesn't 523 00:28:24,040 --> 00:28:26,919 Speaker 2: make it good or bad. I think that there's a 524 00:28:26,960 --> 00:28:29,280 Speaker 2: lot of good oils out there. I think that oil 525 00:28:29,359 --> 00:28:32,440 Speaker 2: technology has really closed the gap on who makes the 526 00:28:32,480 --> 00:28:36,280 Speaker 2: best oil. I think the best oil is the oil 527 00:28:36,320 --> 00:28:40,440 Speaker 2: that's changed on a regular basis, and I think there's 528 00:28:40,480 --> 00:28:41,920 Speaker 2: a lot to be said for that. I think some 529 00:28:41,960 --> 00:28:45,360 Speaker 2: oiales are better than others. But just know that, all right, Kitto, 530 00:28:45,560 --> 00:28:46,920 Speaker 2: I can't wait to hear from you. Let me know 531 00:28:46,920 --> 00:28:48,840 Speaker 2: what happens. Emmett, I'm run any in the Car Doctor. 532 00:28:48,840 --> 00:28:49,960 Speaker 2: We're back right after. 533 00:28:49,720 --> 00:29:05,720 Speaker 7: This Phil in Massachusetts. 534 00:29:05,720 --> 00:29:07,520 Speaker 2: You're up next on the Car Doctor.

I got a 537 00:29:14,920 --> 00:29:18,680 Speaker 4: twenty eighteen sorrent though it's a three lead, a six cylinder, 538 00:29:18,720 --> 00:29:23,560 Speaker 4: OH wheel drive, forty five thousand miles on it, and 539 00:29:23,640 --> 00:29:28,680 Speaker 4: I changed oil every five thousand, and he rotated the tires, 540 00:29:28,720 --> 00:29:34,520 Speaker 4: got new ties at twenty eight thousand, and had one accident. 541 00:29:34,840 --> 00:29:37,560 Speaker 4: I was sideswiped on the front passenger side about three 542 00:29:37,640 --> 00:29:40,280 Speaker 4: years ago, and that was repaired at a body shop. 543 00:29:40,360 --> 00:29:45,200 Speaker 4: So that's the history. Do you have any I have 544 00:29:45,240 --> 00:29:49,280 Speaker 4: two issues in one question. My first issue is a 545 00:29:49,360 --> 00:29:53,680 Speaker 4: consistent rattle or thump evident when I drive at low 546 00:29:53,760 --> 00:29:59,080 Speaker 4: speeds and it's at the same frequency. You know. I 547 00:29:59,120 --> 00:30:00,520 Speaker 4: was due for an oil chair. As I brought it 548 00:30:00,560 --> 00:30:03,800 Speaker 4: to my local mechanic, he took it for a test. 549 00:30:04,080 --> 00:30:06,680 Speaker 4: He re created the sound, you know, he heard it, 550 00:30:07,200 --> 00:30:10,640 Speaker 4: but he could find nothing wrong. So he says, I 551 00:30:10,640 --> 00:30:15,760 Speaker 4: can't find anything wrong. There's nothing loose suspensions. Okay, the 552 00:30:15,880 --> 00:30:18,440 Speaker 4: tires are good. He advised me to take it to 553 00:30:18,520 --> 00:30:26,040 Speaker 4: a dealer. I'm just looking, you know, he he he 554 00:30:26,120 --> 00:30:28,680 Speaker 4: only does like no more maintenance will changes? 555 00:30:28,800 --> 00:30:29,040 Speaker 5: Well? 556 00:30:29,560 --> 00:30:32,560 Speaker 2: Right side or left side of carfell if you were 557 00:30:32,600 --> 00:30:33,800 Speaker 2: to guess. 558 00:30:33,560 --> 00:30:38,080 Speaker 4: Yeah, proximally passion this passenger side center? 559 00:30:38,280 --> 00:30:42,160 Speaker 2: Okay, so do this is it? Is it there when 560 00:30:42,200 --> 00:30:45,040 Speaker 2: you hit a bump? Or is it there just driving along? 561 00:30:46,240 --> 00:30:49,160 Speaker 4: Just driving along and I can hit it at low speeds? 562 00:30:49,280 --> 00:30:51,640 Speaker 2: All right? Does it change if you hit a bump? 563 00:30:53,960 --> 00:30:54,280 Speaker 4: Don't know? 564 00:30:54,640 --> 00:30:56,440 Speaker 2: All right? So if we take it out on the 565 00:30:56,520 --> 00:30:58,200 Speaker 2: road and you got to look for you gotta look 566 00:30:58,240 --> 00:30:59,760 Speaker 2: for the right road, if you know what I'm saying. 567 00:31:00,560 --> 00:31:01,920 Speaker 2: You know, if we were at the shop, I tell 568 00:31:01,920 --> 00:31:03,800 Speaker 2: you it's Smith Street because I make good head up 569 00:31:03,800 --> 00:31:06,160 Speaker 2: the Smith straight, I make a right. There's this little 570 00:31:06,600 --> 00:31:08,280 Speaker 2: whoopedie do in the middle of the road that if 571 00:31:08,280 --> 00:31:09,800 Speaker 2: I catch it just right on the left, if I 572 00:31:09,840 --> 00:31:12,200 Speaker 2: catch it just right on the right, I can always 573 00:31:12,240 --> 00:31:14,720 Speaker 2: put one side of the car in the pothole, if 574 00:31:14,760 --> 00:31:16,520 Speaker 2: you know what I'm saying. So if it makes it 575 00:31:16,560 --> 00:31:17,880 Speaker 2: on the left and not the right, I know it's 576 00:31:17,880 --> 00:31:19,600 Speaker 2: the left side. Then when I go back to the shop, 577 00:31:19,920 --> 00:31:21,840 Speaker 2: I'll be slow going into the driveway and as I 578 00:31:22,440 --> 00:31:25,080 Speaker 2: roll into the driveway. We always we made the lipt 579 00:31:25,080 --> 00:31:26,800 Speaker 2: to the driveway a little bit bigger, and I use 580 00:31:26,800 --> 00:31:28,960 Speaker 2: it for diagnostic purposes. If I hear it when I 581 00:31:29,040 --> 00:31:31,000 Speaker 2: hit the front tire, I go, okay, it's left front. 582 00:31:31,040 --> 00:31:32,240 Speaker 2: If I hear it when I hit the back tire, 583 00:31:32,280 --> 00:31:34,240 Speaker 2: I know it's left rear. At least it gives me 584 00:31:34,280 --> 00:31:38,280 Speaker 2: a direction. If it's nothing, if it doesn't matter when 585 00:31:38,320 --> 00:31:40,040 Speaker 2: it hits a bump, if it's just there while I'm 586 00:31:40,120 --> 00:31:43,360 Speaker 2: rolling along, then I'm going to start looking at different things. 587 00:31:43,360 --> 00:31:45,600 Speaker 2: I'm gonna start thinking about heat shields. I'm gonna start 588 00:31:45,600 --> 00:31:48,800 Speaker 2: thinking about things that are dangling in the wind. One 589 00:31:48,840 --> 00:31:51,440 Speaker 2: of the dangers or problems and trying to diagnose a 590 00:31:51,520 --> 00:31:55,920 Speaker 2: noise on a traditional lift where they're supporting the body 591 00:31:55,960 --> 00:32:00,320 Speaker 2: and the suspension hangs free, is if there's something loose, 592 00:32:00,360 --> 00:32:02,480 Speaker 2: the weight of the suspension is pulling down and it 593 00:32:02,600 --> 00:32:07,280 Speaker 2: might be hiding whatever's rattling. So a drive on lift 594 00:32:07,320 --> 00:32:10,200 Speaker 2: is probably the best thing to use. But that's that's 595 00:32:10,200 --> 00:32:11,280 Speaker 2: how I would approach it. 596 00:32:11,600 --> 00:32:17,720 Speaker 4: Second question, Okay, this one may affect my wife's safety 597 00:32:18,280 --> 00:32:22,000 Speaker 4: the she sits on two cushions on the passioner's seat, 598 00:32:22,120 --> 00:32:24,360 Speaker 4: Because you know she's shorter than I and I'm not 599 00:32:24,440 --> 00:32:28,760 Speaker 4: even tall, so and it's everything's been fine. But about 600 00:32:28,760 --> 00:32:34,240 Speaker 4: a year ago, the passenger airbag off light stays on. 601 00:32:36,640 --> 00:32:39,400 Speaker 4: I tried removing the pillows and her sitting on the 602 00:32:39,640 --> 00:32:43,120 Speaker 4: on the passion seat, and it still stayed on. I 603 00:32:43,200 --> 00:32:45,480 Speaker 4: tried her readjusted her weight to make sure she was 604 00:32:45,480 --> 00:32:47,480 Speaker 4: putting her weight in the seat, and it stayed on. 605 00:32:50,040 --> 00:32:55,720 Speaker 4: Soh you know, so I know by Oko mechinicate, you know, 606 00:32:55,880 --> 00:32:59,600 Speaker 4: he couldn't figure it out. So he again advised to 607 00:32:59,600 --> 00:33:03,680 Speaker 4: go to a any ideas on that is the light 608 00:33:03,760 --> 00:33:07,280 Speaker 4: still on, still goes on and stays on. 609 00:33:07,520 --> 00:33:09,120 Speaker 2: Okay, I'll tell you what. Let me pull over, take 610 00:33:09,120 --> 00:33:11,160 Speaker 2: a pause. When I come back, we'll come right back 611 00:33:11,160 --> 00:33:12,800 Speaker 2: to you. We'll be back with Phil. I'm running Indie 612 00:33:12,800 --> 00:33:32,640 Speaker 2: in the car. Doctor. We'll return right after this ron 613 00:33:32,680 --> 00:33:34,280 Speaker 2: An Indie in the car Doctor here for the final 614 00:33:34,360 --> 00:33:36,400 Speaker 2: ride this hour. Let's go back to Phil and mass. 615 00:33:36,400 --> 00:33:38,720 Speaker 4: Phil. You're there, Yes, I'm here. 616 00:33:38,840 --> 00:33:41,680 Speaker 2: So you know that eighteen Sorrento, if the airbag light 617 00:33:41,800 --> 00:33:44,240 Speaker 2: is on, there's a fault in the system. Has anybody 618 00:33:44,280 --> 00:33:45,280 Speaker 2: scanned this for codes? 619 00:33:46,240 --> 00:33:46,720 Speaker 4: Not yet? 620 00:33:46,840 --> 00:33:49,680 Speaker 2: Okay, so let me ask you a question. How long 621 00:33:49,680 --> 00:33:50,600 Speaker 2: ago did this happen? 622 00:33:52,040 --> 00:33:55,560 Speaker 4: This happened about six months ago. 623 00:33:55,680 --> 00:33:58,960 Speaker 2: All right, does your mechanic I'm not picking on your mechanic. 624 00:33:59,080 --> 00:34:01,840 Speaker 2: I'm just curious. I hear this a lot. Does your 625 00:34:01,880 --> 00:34:03,160 Speaker 2: mechanic own a scan tool? 626 00:34:03,200 --> 00:34:08,440 Speaker 4: Do you know? You know, I do not know. Like 627 00:34:08,520 --> 00:34:12,680 Speaker 4: I said, he's always done new team maintenance, you know, right, well. 628 00:34:12,520 --> 00:34:15,400 Speaker 2: But here's my point. All right, and listen, you and 629 00:34:15,400 --> 00:34:17,440 Speaker 2: I are just having a casual conversation. I Am not 630 00:34:17,480 --> 00:34:19,279 Speaker 2: trying to beat anybody up. I'm just trying to make 631 00:34:19,280 --> 00:34:23,040 Speaker 2: a point. You know, I just went for a dermatology exam, 632 00:34:23,680 --> 00:34:26,000 Speaker 2: and and I went through the whole exam. They looked 633 00:34:26,040 --> 00:34:29,520 Speaker 2: me overhead to toe literally, and there's nothing wrong with me. 634 00:34:29,680 --> 00:34:31,319 Speaker 2: And there was nothing wrong with me, he says, I'm 635 00:34:31,320 --> 00:34:34,120 Speaker 2: in great shape. And the insurance company paid a whole 636 00:34:34,160 --> 00:34:37,319 Speaker 2: lot of money for that test. So you know, why 637 00:34:37,320 --> 00:34:39,239 Speaker 2: wouldn't you when you go to your mechanic, if he 638 00:34:39,280 --> 00:34:42,480 Speaker 2: owns a scan tool, and most of it, most most 639 00:34:42,480 --> 00:34:44,319 Speaker 2: shops have to have a scan tool today even to 640 00:34:44,360 --> 00:34:47,600 Speaker 2: do general maintenance. All right, whether it's brand X, Y 641 00:34:47,719 --> 00:34:50,720 Speaker 2: or Z. And in that scan tool, I can almost 642 00:34:50,800 --> 00:34:53,960 Speaker 2: guarantee you there is the capability to do a complete 643 00:34:54,000 --> 00:34:58,400 Speaker 2: system scan. Wouldn't Phil be willing to pay? I don't know. 644 00:34:58,440 --> 00:35:00,960 Speaker 2: Would Phil be willing to pay fifty seventy five one 645 00:35:01,000 --> 00:35:03,800 Speaker 2: hundred bucks to have a scan done of the car? Hey? Phil, 646 00:35:03,920 --> 00:35:06,640 Speaker 2: it's it's this particular fault. I can't fix it because 647 00:35:06,640 --> 00:35:07,839 Speaker 2: I don't have the rest of the tools. But at 648 00:35:07,880 --> 00:35:09,520 Speaker 2: least when you go to the dealer or you go 649 00:35:09,520 --> 00:35:11,239 Speaker 2: to the next specialist, you at least you know what 650 00:35:11,280 --> 00:35:15,000 Speaker 2: you're looking for. Wouldn't that make you feel better? Isn't that? 651 00:35:15,640 --> 00:35:17,520 Speaker 2: Isn't that kind of like going to the dermatologist and 652 00:35:17,520 --> 00:35:23,279 Speaker 2: getting a skin exam, right, sort of the same thing. 653 00:35:23,840 --> 00:35:26,080 Speaker 2: So somebody's got to do a scan to this car, Phil, 654 00:35:26,200 --> 00:35:28,399 Speaker 2: somebody's gonna have to look this car overhead to toe 655 00:35:29,040 --> 00:35:32,239 Speaker 2: and determine why that's like that.
