1
00:00:00,680 --> 00:00:03,880
Speaker 1: Ron an Aian. Sometimes you run into brick walls with

2
00:00:04,200 --> 00:00:06,600
Speaker 1: repairing a car, but it's not the car. Sometimes it's

3
00:00:06,600 --> 00:00:08,880
Speaker 1: the car. Sometimes you gotta wait, you gotta get the

4
00:00:08,880 --> 00:00:11,640
Speaker 1: go ahead. The car doctor. But when he scans it,

5
00:00:11,720 --> 00:00:14,400
Speaker 1: what is he seeing? What fult code is popping up?

6
00:00:14,600 --> 00:00:17,319
Speaker 1: The only thing that he is seeing is something with

7
00:00:17,440 --> 00:00:19,439
Speaker 1: the third or fourth injectors.

8
00:00:19,600 --> 00:00:21,880
Speaker 2: And he had his computer on it, and he Chase said,

9
00:00:21,920 --> 00:00:23,320
Speaker 2: the injectors are fine.

10
00:00:23,120 --> 00:00:24,160
Speaker 1: They're working perfect.

11
00:00:24,280 --> 00:00:27,960
Speaker 3: Welcome to the radio home of ron Ananian, the Car Doctor.

12
00:00:28,200 --> 00:00:31,319
Speaker 3: Since nineteen ninety one, this is where car owners the

13
00:00:31,360 --> 00:00:35,640
Speaker 3: world overturned to for their definitive opinion on automotive repair.

14
00:00:36,120 --> 00:00:38,919
Speaker 3: If your mechanics giving you a busy signal, pick up

15
00:00:38,920 --> 00:00:40,239
Speaker 3: the phone and call in.

16
00:00:40,680 --> 00:00:43,240
Speaker 1: The garage doors are open, but I am here to

17
00:00:43,280 --> 00:00:46,000
Speaker 1: take your calls at eight five five five six ninety

18
00:00:46,040 --> 00:00:52,120
Speaker 1: nine hundred and now he running. I tell you this

19
00:00:52,200 --> 00:00:57,000
Speaker 1: story one hundred times. I love that scene in I

20
00:00:57,040 --> 00:00:59,760
Speaker 1: think it's Star Trek three where they go back in

21
00:00:59,800 --> 00:01:03,640
Speaker 1: time to San Francisco and they're trying to get back

22
00:01:04,040 --> 00:01:07,039
Speaker 1: to present day from I think it's the San Francisco

23
00:01:07,080 --> 00:01:08,959
Speaker 1: in nineteen sixty eight or something. You know, they have

24
00:01:09,000 --> 00:01:10,400
Speaker 1: to go back to get the whale, to bring the

25
00:01:10,440 --> 00:01:13,480
Speaker 1: whale forward to save humanity because we've wiped out the

26
00:01:13,480 --> 00:01:16,800
Speaker 1: whale three hundred years from now and something crazy like that.

27
00:01:17,520 --> 00:01:21,680
Speaker 1: And Spock's trying to calculate the speed that they have

28
00:01:21,800 --> 00:01:24,039
Speaker 1: to get up to for the sling shot around the

29
00:01:24,080 --> 00:01:27,200
Speaker 1: sun to break free of gravity to do the time

30
00:01:27,280 --> 00:01:30,600
Speaker 1: travel thing, and he just tells Captain Kirk, you know,

31
00:01:30,640 --> 00:01:32,760
Speaker 1: he can't figure it out exactly, and Kirk kind of

32
00:01:32,760 --> 00:01:36,200
Speaker 1: gives him that, well, take your best guess, Bock, because

33
00:01:36,400 --> 00:01:40,600
Speaker 1: I trust that. And Spock is confused by guess, what's

34
00:01:40,600 --> 00:01:45,200
Speaker 1: a guess? I can relate to that because sometimes as

35
00:01:45,200 --> 00:01:48,160
Speaker 1: a mechanic, you have to guess and it kind of

36
00:01:48,200 --> 00:01:51,680
Speaker 1: blows your mind. You're just like, wait a minute. I've

37
00:01:51,680 --> 00:01:54,600
Speaker 1: been trained to do it as very specific, you know,

38
00:01:54,840 --> 00:01:58,320
Speaker 1: sequential way of doing things and test test test, test tests.

39
00:01:58,520 --> 00:02:00,360
Speaker 1: All right, go ahead and we'll guess. We'll try try this.

40
00:02:01,640 --> 00:02:04,040
Speaker 1: It's you know, I can just hear Spock in my

41
00:02:04,680 --> 00:02:06,800
Speaker 1: mind going, well, then I'll make the best guess I

42
00:02:06,840 --> 00:02:10,920
Speaker 1: possibly can. And sometimes you have to do that. I

43
00:02:10,960 --> 00:02:13,240
Speaker 1: had a twenty twelve Toyota Raft four in the shop

44
00:02:13,280 --> 00:02:16,880
Speaker 1: this week and it set a P zero six oh

45
00:02:17,040 --> 00:02:23,360
Speaker 1: seven fault code module performance fault. Now flashback two years ago.

46
00:02:24,040 --> 00:02:26,360
Speaker 1: It had a P zero one thirty eight and a

47
00:02:26,400 --> 00:02:30,600
Speaker 1: P zero six oh seven at forty two thousand miles,

48
00:02:31,560 --> 00:02:33,519
Speaker 1: and there was a bulletin for it, and it talked

49
00:02:33,560 --> 00:02:37,400
Speaker 1: about that. Even though the P zero one thirty eight

50
00:02:37,639 --> 00:02:42,239
Speaker 1: referenced the downstream oxygen sensor on this four cylinder RAF four.

51
00:02:43,080 --> 00:02:48,240
Speaker 1: Toyota's repair, as per the bulletin, was a software update

52
00:02:48,280 --> 00:02:52,160
Speaker 1: to the PCM and to replace the air fuel ratio sensor,

53
00:02:52,200 --> 00:02:54,400
Speaker 1: which is the fancy oxygen sensor in the front of

54
00:02:54,440 --> 00:02:59,320
Speaker 1: the catalytic converter, and it fixed it. Car was fine

55
00:03:00,320 --> 00:03:03,720
Speaker 1: two years and twenty six thousand miles later. The light's

56
00:03:03,720 --> 00:03:07,600
Speaker 1: coming back on, all right, only cold. It starts out

57
00:03:07,639 --> 00:03:10,600
Speaker 1: doing it cold and then it'll go off, and then

58
00:03:10,639 --> 00:03:12,520
Speaker 1: it'll come on and it'll go off. But it's from

59
00:03:12,560 --> 00:03:16,160
Speaker 1: a cold start, and it's only got a P zero

60
00:03:16,200 --> 00:03:20,519
Speaker 1: six oh seven module performance faull. If you read Toyota's

61
00:03:20,520 --> 00:03:23,800
Speaker 1: float chart, you go through it, they tell you, well,

62
00:03:23,840 --> 00:03:26,240
Speaker 1: it could be an exhaust leak, it could be a

63
00:03:26,280 --> 00:03:29,720
Speaker 1: bad air fuel sensor, which I'm going well, could be

64
00:03:30,120 --> 00:03:33,519
Speaker 1: but h Toyota part to fail in two years and

65
00:03:33,560 --> 00:03:35,720
Speaker 1: twenty six thousand miles. You kind of play that against

66
00:03:35,760 --> 00:03:37,960
Speaker 1: your head. You're trying not to get emotional, but you know,

67
00:03:38,080 --> 00:03:42,160
Speaker 1: prove it, or it could be a PCM, which is

68
00:03:42,600 --> 00:03:45,640
Speaker 1: you know, seven eight hundred, twelve hundred dollars, whatever it is,

69
00:03:48,320 --> 00:03:52,680
Speaker 1: it's time to do some diagnostic So I ran through

70
00:03:52,720 --> 00:03:55,240
Speaker 1: and I looked at as much information as I had

71
00:03:55,280 --> 00:03:57,119
Speaker 1: available to me. What I always tell you guys, what's

72
00:03:57,120 --> 00:04:01,680
Speaker 1: the three rules of a diagnosis? Research? Research, research? And

73
00:04:02,360 --> 00:04:05,600
Speaker 1: I came to a conclusion that because this happened when

74
00:04:05,600 --> 00:04:09,119
Speaker 1: it was cold, that you know, I could have either

75
00:04:09,160 --> 00:04:13,560
Speaker 1: a wiring fault, I could have a bad downstream mode

76
00:04:13,560 --> 00:04:17,000
Speaker 1: two because interestingly, the six h seven is stating when

77
00:04:17,040 --> 00:04:19,320
Speaker 1: you do deep dive. When you do a deep dive,

78
00:04:19,839 --> 00:04:23,720
Speaker 1: it's saying that the data it's receiving from its downstream

79
00:04:23,839 --> 00:04:28,719
Speaker 1: oxygen sensor doesn't match what's in its lookup table versus

80
00:04:28,720 --> 00:04:32,159
Speaker 1: how the transistors are reporting it. It's an internal PCM failure.

81
00:04:34,160 --> 00:04:37,200
Speaker 1: I wanted more information. Once again, I reached out and

82
00:04:37,240 --> 00:04:39,480
Speaker 1: I fucked. I think I talked to Meryl over at

83
00:04:39,520 --> 00:04:42,680
Speaker 1: Opus IVS. This is what's so great about them. They

84
00:04:42,720 --> 00:04:45,680
Speaker 1: have access to real Toyota factory information. It was wonderful

85
00:04:46,200 --> 00:04:51,640
Speaker 1: and we kind of kicked it around and with Marlon Marlon, Meryl, Caddy, Keddy, whatever,

86
00:04:52,279 --> 00:04:56,599
Speaker 1: and you know, we decided time to make a guess.

87
00:04:57,240 --> 00:04:59,320
Speaker 1: He went through Toyota information. He talked to a couple

88
00:04:59,400 --> 00:05:01,240
Speaker 1: of Toyota tw that are you know, still in the

89
00:05:01,240 --> 00:05:03,840
Speaker 1: dealership because he's on the hot line, and we all

90
00:05:03,880 --> 00:05:05,479
Speaker 1: ran it around the table and we all came to

91
00:05:05,520 --> 00:05:08,359
Speaker 1: the same conclusion, it's time to guess. We'll start with

92
00:05:08,400 --> 00:05:11,920
Speaker 1: an oxygen sensor, because if it's not an oxygen sensor,

93
00:05:11,920 --> 00:05:14,240
Speaker 1: it's either a PCM or wiring, and both of those

94
00:05:14,279 --> 00:05:16,680
Speaker 1: are more involved than to change an oxygen sensor on

95
00:05:16,760 --> 00:05:20,479
Speaker 1: an eleven year old sixty eight thousand mile rav four.

96
00:05:20,720 --> 00:05:23,960
Speaker 1: It's not the worst idea in the world. Right two

97
00:05:24,040 --> 00:05:29,279
Speaker 1: sensors are cheap relatively speaking. So I, you know, ordered

98
00:05:29,320 --> 00:05:33,640
Speaker 1: a brand new right from Toyota OE style two sensor,

99
00:05:33,880 --> 00:05:36,280
Speaker 1: took it out of the box, and it's interesting. Right

100
00:05:36,560 --> 00:05:41,280
Speaker 1: lo and behold. Where there are four holes in the

101
00:05:41,320 --> 00:05:45,120
Speaker 1: original two sensor, the body that's inserted into the exhaust stream,

102
00:05:45,120 --> 00:05:47,840
Speaker 1: there's four sensing or breathing holes if we want to

103
00:05:47,880 --> 00:05:51,800
Speaker 1: call it that, the new sensor has a different design.

104
00:05:51,880 --> 00:05:56,679
Speaker 1: The new sensor has sixteen holes in it. They've given

105
00:05:56,720 --> 00:06:01,679
Speaker 1: it a much more open breathing surface. Gee, that's different.

106
00:06:02,080 --> 00:06:03,880
Speaker 1: I like different. I like when I see things that

107
00:06:03,920 --> 00:06:06,000
Speaker 1: are different. I wish I knew the reason why. I

108
00:06:06,040 --> 00:06:08,000
Speaker 1: wish I know, I would apply to this vehicle. But

109
00:06:08,440 --> 00:06:11,080
Speaker 1: there are some things I've come to accept that unless

110
00:06:11,120 --> 00:06:13,159
Speaker 1: i'm you know, unless I go to lunch with the

111
00:06:13,200 --> 00:06:15,840
Speaker 1: engineer and I get every engineer that I've ever got

112
00:06:15,880 --> 00:06:18,240
Speaker 1: a question about, I never get any cars fixed. But

113
00:06:19,200 --> 00:06:23,000
Speaker 1: I put it in. So far it's fixed. Hey, that

114
00:06:23,120 --> 00:06:26,479
Speaker 1: was four days ago. Car hasn't come back. We test

115
00:06:26,560 --> 00:06:29,040
Speaker 1: drove it the next day from a cold start, and

116
00:06:29,120 --> 00:06:31,320
Speaker 1: it ran the O two monitor. And why is that

117
00:06:31,400 --> 00:06:33,279
Speaker 1: so important? You know you hear me talk about, Hey,

118
00:06:33,279 --> 00:06:36,880
Speaker 1: it ran its monitor. What does that mean? Well, the

119
00:06:37,000 --> 00:06:42,000
Speaker 1: monitor or the computer self test ran, meaning the computer

120
00:06:42,120 --> 00:06:46,640
Speaker 1: saw the right conditions to test that component in its

121
00:06:46,680 --> 00:06:50,200
Speaker 1: operating environment. It said, Hey, let me put you through

122
00:06:50,240 --> 00:06:51,840
Speaker 1: the mill. Let me let me run your high, let

123
00:06:51,839 --> 00:06:53,800
Speaker 1: me run your low, let me put you through the gamut.

124
00:06:53,880 --> 00:06:55,640
Speaker 1: Let me make sure that you can operate in all

125
00:06:55,680 --> 00:06:59,479
Speaker 1: the ranges. And perform as expected, correct response, correct signal,

126
00:06:59,800 --> 00:07:02,360
Speaker 1: so on and so forth, and it passed, it ran

127
00:07:02,440 --> 00:07:06,599
Speaker 1: its monitor completion, didn't set a pending fault, didn't send,

128
00:07:06,760 --> 00:07:11,040
Speaker 1: didn't set a hard fault. And that tells me that,

129
00:07:11,320 --> 00:07:13,080
Speaker 1: you know, I don't know what time is it now

130
00:07:13,160 --> 00:07:15,800
Speaker 1: up till today. In this moment in time, Hey, that

131
00:07:15,840 --> 00:07:18,640
Speaker 1: computer is happy. And if the computer is happy, you know,

132
00:07:18,760 --> 00:07:21,640
Speaker 1: computers are a lot like wives. If they're not happy,

133
00:07:21,680 --> 00:07:28,000
Speaker 1: nobody's happy, so said the married guy. And you know,

134
00:07:28,880 --> 00:07:33,600
Speaker 1: so it works. So you know, the point becomes, Yeah,

135
00:07:33,760 --> 00:07:37,000
Speaker 1: sometimes you can do your research, you can do your diagnosis,

136
00:07:37,760 --> 00:07:39,760
Speaker 1: and you can do a deep dive, but when you

137
00:07:39,760 --> 00:07:43,760
Speaker 1: get into that eighty five ninety percent tile, you know,

138
00:07:44,440 --> 00:07:46,640
Speaker 1: sometimes you got to take that guess. And whether you're

139
00:07:46,640 --> 00:07:48,400
Speaker 1: trying to slingshot around the sun to get back to

140
00:07:48,440 --> 00:07:50,640
Speaker 1: the present day and time travel, or whether you're just

141
00:07:50,680 --> 00:07:52,680
Speaker 1: trying to get that twelve Toyota RAF four out the

142
00:07:52,720 --> 00:07:55,920
Speaker 1: door to keep it from sitting that P zero six

143
00:07:56,000 --> 00:07:58,000
Speaker 1: oh seven. Either way, you're going to come out ahead

144
00:07:58,400 --> 00:08:01,240
Speaker 1: if you guess right. Guessing right is always a good

145
00:08:01,240 --> 00:08:02,840
Speaker 1: thing on order repair. You just got to have some

146
00:08:02,880 --> 00:08:06,080
Speaker 1: research to back it up. Hello and welcome AKA, I'm

147
00:08:06,120 --> 00:08:07,720
Speaker 1: Ronning Ay and the car doctor here at eight five

148
00:08:07,840 --> 00:08:11,560
Speaker 1: five five six zho nine nine zero zero. Almost forgot

149
00:08:11,560 --> 00:08:12,080
Speaker 1: the phone number?

150
00:08:12,080 --> 00:08:12,200
Speaker 4: Tom?

151
00:08:12,240 --> 00:08:13,880
Speaker 1: How many times a year? How many times a day

152
00:08:13,880 --> 00:08:15,240
Speaker 1: do I give that out? I could probably do that

153
00:08:15,280 --> 00:08:18,720
Speaker 1: in my sleep most times. But you know that happens

154
00:08:18,720 --> 00:08:22,200
Speaker 1: when you, you know, start getting up there in years. Well, yeah,

155
00:08:22,200 --> 00:08:24,120
Speaker 1: it's you know, and yeah, but I'm not up there yet.

156
00:08:24,400 --> 00:08:26,160

Speaker 1: of email during the week they want to and you

164
00:08:41,360 --> 00:08:43,120
Speaker 1: know it's getting harder and harder, right, so you know,

165
00:08:43,160 --> 00:08:46,360
Speaker 1: we'd rather do a recording session on Wednesday nights. Although

166
00:08:46,360 --> 00:08:48,120
Speaker 1: this Wednesday night, I can tell you I will not

167
00:08:48,200 --> 00:08:51,480
Speaker 1: be around this Wednesday night. Automotive training group the infamous

168
00:08:51,520 --> 00:08:54,840
Speaker 1: Chris Lewis, is running a training class in Edison, New Jersey,

169
00:08:54,840 --> 00:08:58,040
Speaker 1: two nights Wednesday and Thursday, and Evans driveability Diagnostics, and

170
00:08:58,040 --> 00:08:59,440
Speaker 1: I'll be sitting in the back of the room throwing

171
00:08:59,440 --> 00:09:02,080
Speaker 1: spitballs at Chris and uh, you know, I'm trying to

172
00:09:02,080 --> 00:09:03,640
Speaker 1: pick up a few things here and there because it's

173
00:09:03,640 --> 00:09:06,120
Speaker 1: always good to get good new information and stay current

174
00:09:06,120 --> 00:09:08,000
Speaker 1: because you're always going back to school. That's one thing

175
00:09:08,040 --> 00:09:10,800
Speaker 1: about auto repair. You never really graduate. You're always just

176
00:09:10,800 --> 00:09:13,000
Speaker 1: waiting until the next class rolls around. It's kind of

177
00:09:13,000 --> 00:09:15,120
Speaker 1: like owning a class like hot rod. It's not really yours.

178
00:09:15,120 --> 00:09:16,559
Speaker 1: You're just keeping track of it till you give it

179
00:09:16,600 --> 00:09:19,160
Speaker 1: to the next guy. In the next generation auto repair,

180
00:09:19,360 --> 00:09:21,240
Speaker 1: You're always going to class. You're always trying to get

181
00:09:21,280 --> 00:09:24,400
Speaker 1: something new. So you know, ATG puts on a great

182
00:09:24,440 --> 00:09:26,520
Speaker 1: seminar and I'm looking forward to that and then we'll

183
00:09:26,520 --> 00:09:28,120
Speaker 1: have one hundred new things to talk about the next

184
00:09:28,160 --> 00:09:30,280
Speaker 1: time you hear my voice up here on air. So

185
00:09:30,520 --> 00:09:32,360
Speaker 1: let's pull over and take a pause. Eight five five

186
00:09:32,400 --> 00:09:34,600

Speaker 1: And now back to Ron. Hey, let's get on over

197
00:09:55,920 --> 00:09:58,679
Speaker 1: and talk to Jan in Wisconsin O. Six Pulic concern

198
00:09:59,040 --> 00:10:01,160
Speaker 1: and some questions about the transmission. Jan, Welcome to the

199
00:10:01,200 --> 00:10:03,840
Speaker 1: car doctor. How can I help? Hi?

200
00:10:04,240 --> 00:10:05,439
Speaker 5: Thank you for taking my call.

201
00:10:05,559 --> 00:10:06,080
Speaker 1: You're welcome.

202
00:10:06,160 --> 00:10:09,400
Speaker 5: Yeah, I have what I've been told is a slipping

203
00:10:09,440 --> 00:10:12,480
Speaker 5: of my transmission. It's been going on for about two years.

204
00:10:12,760 --> 00:10:12,880
Speaker 1: Right.

205
00:10:13,720 --> 00:10:17,800
Speaker 5: Uh, my son took out a court of transmission fluid

206
00:10:18,200 --> 00:10:21,920
Speaker 5: and it was black, and he put in some Lucas

207
00:10:21,960 --> 00:10:26,640
Speaker 5: stop slip, okay, and that seemed to help a little bit,

208
00:10:26,800 --> 00:10:29,480
Speaker 5: but it still continues. It's been going on for two years.

209
00:10:29,480 --> 00:10:31,160
Speaker 1: Like how many miles around the car? Jan?

210
00:10:32,520 --> 00:10:33,959
Speaker 5: One hundred and sixty two thousand?

211
00:10:34,120 --> 00:10:36,600
Speaker 1: Okay, So you owe the car transmission, you know that? Right?

212
00:10:38,200 --> 00:10:40,560
Speaker 1: What's that you owe the car transmission at this age

213
00:10:40,559 --> 00:10:42,280
Speaker 1: in mileage? Right? So you're not going to be surprised

214
00:10:42,280 --> 00:10:43,359
Speaker 1: when the trans fails.

215
00:10:43,160 --> 00:10:47,240
Speaker 5: Right, right? Well, that's my question. What happens when the

216
00:10:47,280 --> 00:10:52,080
Speaker 5: transmission fails? And also the other question I had was

217
00:10:53,360 --> 00:10:56,120
Speaker 5: it also shifts hard when I park it on a slant.

218
00:10:56,600 --> 00:10:59,760
Speaker 1: Okay? So does that have to do with when you

219
00:10:59,800 --> 00:11:03,240
Speaker 1: say shift hard if you're parked, how is it shifting?

220
00:11:03,760 --> 00:11:06,760
Speaker 1: Are you saying it's hard to put it in park's park?

221
00:11:07,160 --> 00:11:10,240
Speaker 5: It's hard to get it into drive or reverse, like

222
00:11:10,280 --> 00:11:11,120
Speaker 5: if I'm on an.

223
00:11:11,000 --> 00:11:15,000
Speaker 1: Uphill, okay? Is okay? So when you park on an

224
00:11:15,040 --> 00:11:17,760
Speaker 1: uphill on a slant up or down, are you setting

225
00:11:17,800 --> 00:11:22,520
Speaker 1: the parking brake? No, I'm not set the parking brake.

226
00:11:23,880 --> 00:11:26,960
Speaker 1: All right. Take take your index finger on your right hand,

227
00:11:28,440 --> 00:11:31,880
Speaker 1: all right, and put it between your thumb and forefinger

228
00:11:32,360 --> 00:11:35,600
Speaker 1: and your other hand. All right, so you should have

229
00:11:35,640 --> 00:11:38,079
Speaker 1: two fingers wrapped around one finger right now, correct?

230
00:11:39,480 --> 00:11:40,200
Speaker 2: Yeah, all right?

231
00:11:40,480 --> 00:11:43,680
Speaker 1: That index That that singular finger that's between the two.

232
00:11:45,000 --> 00:11:48,640
Speaker 1: That's the that's the metal lock inside the transmission, sitting

233
00:11:48,720 --> 00:11:51,960
Speaker 1: in the indent against the main shaft of the trans

234
00:11:52,000 --> 00:11:53,960
Speaker 1: That's how the trans locks and keeps the car from

235
00:11:54,000 --> 00:11:57,640
Speaker 1: rolling away. So all the weight is on that one finger,

236
00:11:58,320 --> 00:12:00,280
Speaker 1: all right. So when you're parked on a hill, you're

237
00:12:00,280 --> 00:12:04,319
Speaker 1: stressing that that index finger. In extreme cases, you put

238
00:12:04,320 --> 00:12:06,240
Speaker 1: it in too hard, you pull it out too hard,

239
00:12:06,440 --> 00:12:09,079
Speaker 1: you will that is just a mechanical lock. You will

240
00:12:09,120 --> 00:12:12,280
Speaker 1: break it, all right, if you put the parking brake

241
00:12:12,360 --> 00:12:16,520
Speaker 1: on first to keep the car from rolling. All right, Now,

242
00:12:16,600 --> 00:12:19,280
Speaker 1: when you put your one finger between the two fingers,

243
00:12:19,480 --> 00:12:21,480
Speaker 1: there's a little bit of play there because the car

244
00:12:21,600 --> 00:12:24,360
Speaker 1: isn't rolling and pushing against the weight of the one finger,

245
00:12:24,400 --> 00:12:26,880
Speaker 1: locking it against the front or back of those other

246
00:12:26,920 --> 00:12:28,160
Speaker 1: two fingers. If you follow what.

247
00:12:28,120 --> 00:12:31,360
Speaker 5: I'm saying, I do follow them. That makes sense.

248
00:12:31,440 --> 00:12:35,640
Speaker 1: So you're you're you're basically you're stressing the park pole

249
00:12:35,760 --> 00:12:39,000
Speaker 1: pawl is what we call that, the park pole or

250
00:12:39,080 --> 00:12:42,280
Speaker 1: the park lock pin. So using the parking brake will

251
00:12:42,280 --> 00:12:46,080
Speaker 1: eliminate that. Back to the first problem, Okay, go ahead.

252
00:12:46,440 --> 00:12:50,320
Speaker 5: The other question with that is I've hardly ever used

253
00:12:50,320 --> 00:12:52,880
Speaker 5: the parking brake, So if I put it on, will

254
00:12:52,920 --> 00:12:54,959
Speaker 5: it kind of free up?

255
00:12:55,240 --> 00:12:59,440
Speaker 1: Well, we hope, we hope. Uh, you know, it's a

256
00:12:59,440 --> 00:13:03,160
Speaker 1: fair question, right, So it's it's listen, you're slowly approaching

257
00:13:03,200 --> 00:13:05,440
Speaker 1: the moment with this car, all right, where we're going

258
00:13:05,520 --> 00:13:06,800
Speaker 1: to You and I are going to have that heart

259
00:13:06,840 --> 00:13:08,920
Speaker 1: to heart. You know, how much do you love the car?

260
00:13:09,000 --> 00:13:10,880
Speaker 1: How much do you like the car? And it sounds

261
00:13:11,000 --> 00:13:13,120
Speaker 1: like you do because you're driving an eighteen year old

262
00:13:13,120 --> 00:13:15,240
Speaker 1: car with one hundred and sixty five thousand miles on it.

263
00:13:15,920 --> 00:13:19,400
Speaker 1: You know this is so. Now the question becomes what

264
00:13:19,520 --> 00:13:21,000
Speaker 1: kind of shape is the rest of the car? And

265
00:13:21,160 --> 00:13:24,719
Speaker 1: if the trans were to fail tomorrow, would you put

266
00:13:24,720 --> 00:13:28,960
Speaker 1: a trans in it? No? No, Well then you're on

267
00:13:29,040 --> 00:13:33,720
Speaker 1: borrowed time, right, yep, yep? So you know, then the

268
00:13:33,760 --> 00:13:35,240
Speaker 1: next question becomes what color?

269
00:13:37,440 --> 00:13:40,000
Speaker 5: Yeah, well I've been I've been looking. I've been looking

270
00:13:40,040 --> 00:13:42,400
Speaker 5: for other cars. As a matter of fact, that's kind

271
00:13:42,400 --> 00:13:45,240
Speaker 5: of the reason why I called is because I was wondering. Okay,

272
00:13:45,320 --> 00:13:48,080
Speaker 5: so what happens when the transmission fails? Does it just

273
00:13:48,160 --> 00:13:51,120
Speaker 5: not go in to a certain gear or does it stop?

274
00:13:51,280 --> 00:13:52,920
Speaker 1: Yeah? Is the car sitting in the garage?

275
00:13:52,960 --> 00:13:56,240
Speaker 5: Now, I don't have a garage that's sitting on my

276
00:13:56,320 --> 00:13:56,920
Speaker 5: parking pad.

277
00:13:57,080 --> 00:13:59,360
Speaker 1: Okay, so the car will move at the same speed

278
00:13:59,400 --> 00:14:03,200
Speaker 1: it's moving now, know, meaning zero, it just sits there. Okay,

279
00:14:03,280 --> 00:14:05,800
Speaker 1: when the trans fails, You're done. Now could the trans

280
00:14:05,800 --> 00:14:09,360
Speaker 1: stop on the road? Sure? Could the trans stop? You know,

281
00:14:09,840 --> 00:14:13,559
Speaker 1: in a highway situation? Yeah? You know, do I think

282
00:14:13,600 --> 00:14:14,199
Speaker 1: that'll happen?

283
00:14:14,320 --> 00:14:14,800
Speaker 3: Yeah? Yeah.

284
00:14:15,000 --> 00:14:18,520
Speaker 1: Listen, there's you know, there's no rule that says once

285
00:14:18,559 --> 00:14:22,400
Speaker 1: the car is moving on a trend. Listen, the transmission's failing, right,

286
00:14:22,480 --> 00:14:26,600
Speaker 1: it's telling you it's failing. It's slipping. Yeah, we've the

287
00:14:26,640 --> 00:14:29,400
Speaker 1: fluid has gone black. The reason the fluid has gone

288
00:14:29,480 --> 00:14:33,280
Speaker 1: black is because the transit the fluid's overheated. The fluids

289
00:14:33,280 --> 00:14:36,760
Speaker 1: worked harder than it has to. It's dying a slow death.

290
00:14:37,800 --> 00:14:40,520
Speaker 1: So you can't be surprised when it stops.

291
00:14:40,760 --> 00:14:43,400
Speaker 2: You can't, right, I'm not.

292
00:14:43,600 --> 00:14:45,440
Speaker 5: I'm not going to be surprised when it stops. But

293
00:14:45,480 --> 00:14:47,400
Speaker 5: I don't know what happens when it does fail.

294
00:14:47,560 --> 00:14:51,040
Speaker 1: Well, it's the car stops period. You're on the side,

295
00:14:51,080 --> 00:14:53,320
Speaker 1: you're on the side of the road. Is that going

296
00:14:53,360 --> 00:14:57,640
Speaker 1: to happen? I don't know. Nobody knows, you know, you know,

297
00:14:57,720 --> 00:14:59,960
Speaker 1: so now the question is we have to keep you sick.

298
00:15:01,160 --> 00:15:03,440
Speaker 1: This is like driving around on a car with a

299
00:15:03,440 --> 00:15:07,800
Speaker 1: bad wheel bearing, all right, you know that it's making

300
00:15:07,880 --> 00:15:11,480
Speaker 1: noise and you're like, well, when's that going to fail?

301
00:15:11,600 --> 00:15:14,520
Speaker 1: I don't know. Bad is bad? And how many times

302
00:15:14,520 --> 00:15:16,240
Speaker 1: people say to me, Hey, I've got a bad wheel bearing,

303
00:15:16,280 --> 00:15:17,760
Speaker 1: how long do you think I can drive? Oh? I

304
00:15:17,760 --> 00:15:22,280
Speaker 1: don't know. A week, you know. And I don't mean

305
00:15:22,320 --> 00:15:25,480
Speaker 1: to sound dramatic. I'm just the road is a very

306
00:15:25,520 --> 00:15:29,600
Speaker 1: unforgiving place. Jan You know, there's nothing worse than getting

307
00:15:29,600 --> 00:15:32,880
Speaker 1: stuck and being at the mercy of the road. You know,

308
00:15:33,840 --> 00:15:37,400
Speaker 1: in these times, I feel like going out on the road. Sometimes,

309
00:15:37,480 --> 00:15:39,720
Speaker 1: depending on how far you're away from home and what

310
00:15:39,840 --> 00:15:41,400
Speaker 1: time of the day it is, and what hour of

311
00:15:41,440 --> 00:15:43,160
Speaker 1: the day and what kind of weather you're traveling in,

312
00:15:43,960 --> 00:15:45,520
Speaker 1: you know, things can be a little tougher than they

313
00:15:45,600 --> 00:15:47,280
Speaker 1: need to be. So I think it's time you've got

314
00:15:47,320 --> 00:15:49,800
Speaker 1: to consider. Yeah, it's time to replace the car or

315
00:15:49,880 --> 00:15:52,520
Speaker 1: fix it one or the other. You know, I want you, say,

316
00:15:52,520 --> 00:15:53,920
Speaker 1: if I want you around for a long time, at

317
00:15:54,000 --> 00:15:54,800
Speaker 1: least to listen to me.

318
00:15:55,800 --> 00:15:58,560
Speaker 5: All right, yeah, right, thank you very much.

319
00:15:58,600 --> 00:16:01,760
Speaker 1: You're very welcome. So and uh, I wish you well

320
00:16:01,760 --> 00:16:07,120
Speaker 1: in your choice. All right, thank you bye. Now, yeah, listen,

321
00:16:07,120 --> 00:16:10,480
Speaker 1: there's no there's no second guess in this, guys. It's

322
00:16:10,560 --> 00:16:15,480
Speaker 1: it's and it's hard, right. Look, I think buying a

323
00:16:15,520 --> 00:16:19,160
Speaker 1: new car today, it's it's it's not the expense. It

324
00:16:19,200 --> 00:16:21,520
Speaker 1: is the expense, but it's not the expense. There are

325
00:16:21,560 --> 00:16:24,000
Speaker 1: so many options, there are so many choices, There are

326
00:16:24,040 --> 00:16:27,000
Speaker 1: so many you know, features, and and how do I

327
00:16:27,040 --> 00:16:29,280
Speaker 1: go about it? And how does this work? And there's

328
00:16:29,280 --> 00:16:32,600
Speaker 1: a culture shock. Jen is going to go into a

329
00:16:32,640 --> 00:16:36,360
Speaker 1: new car dealership and she is going to be astounded

330
00:16:36,760 --> 00:16:39,320
Speaker 1: by the technology that's in that next new car. Whatever

331
00:16:39,360 --> 00:16:42,400
Speaker 1: it is. There's no more dashboard. It's an iPad or

332
00:16:42,440 --> 00:16:45,000
Speaker 1: a tablet or a laptop, whatever we want to call it.

333
00:16:46,280 --> 00:16:47,720
Speaker 1: And it's going to sit in the middle of the screen,

334
00:16:47,800 --> 00:16:50,160
Speaker 1: right between the passenger and the driver, and that's where

335
00:16:50,160 --> 00:16:52,720
Speaker 1: all the controls are going to be. And it might

336
00:16:52,760 --> 00:16:55,560
Speaker 1: as well be the Star Trek Enterprise, okay, because it's

337
00:16:55,600 --> 00:16:58,240
Speaker 1: like a spaceship, it really is. And I hear this

338
00:16:58,320 --> 00:17:01,400
Speaker 1: all the time that people coming out, you know, they're

339
00:17:01,400 --> 00:17:03,840
Speaker 1: coming out She's coming out of a two thousand and six.

340
00:17:04,520 --> 00:17:05,920
Speaker 1: You know what, have we got an eighteen year old

341
00:17:05,960 --> 00:17:09,159
Speaker 1: vehicle there? She's coming out of something that's Yeah, it

342
00:17:09,600 --> 00:17:11,760
Speaker 1: would be like somebody that flew on the Right Brothers

343
00:17:11,800 --> 00:17:14,000
Speaker 1: aircraft and now they got into the Space Shuttle literally

344
00:17:14,920 --> 00:17:18,040
Speaker 1: and are they used to all that? And you know,

345
00:17:18,280 --> 00:17:21,000
Speaker 1: do they have the ability Do we as human beings

346
00:17:21,080 --> 00:17:23,880
Speaker 1: have the ability to adapt to that new car at

347
00:17:23,880 --> 00:17:29,320
Speaker 1: a comfort level? It's you know, I look at when

348
00:17:29,359 --> 00:17:31,159
Speaker 1: I get a new cell phone, when I get a

349
00:17:31,200 --> 00:17:35,159
Speaker 1: new cell phone better. Example, when my current cell phone breaks,

350
00:17:35,720 --> 00:17:38,080
Speaker 1: I don't want a new cell phone. I want them

351
00:17:38,080 --> 00:17:40,520
Speaker 1: to warrantye and send me the exact same model because

352
00:17:40,560 --> 00:17:42,960
Speaker 1: I know how that one works. I don't have time

353
00:17:43,000 --> 00:17:47,160
Speaker 1: to relearn how to use a cell phone. Maybe cars

354
00:17:47,200 --> 00:17:49,120
Speaker 1: are a little different. Maybe I'm forced into it. Maybe

355
00:17:49,160 --> 00:17:51,080
Speaker 1: I've got to just you know. Okay, Ron, you got

356
00:17:51,080 --> 00:17:53,840
Speaker 1: to get with the times, right, heated cup holders, air

357
00:17:53,840 --> 00:17:56,879
Speaker 1: conditioned cup holders, whatever the fancy option is. But the

358
00:17:56,960 --> 00:17:59,840
Speaker 1: learning curve is huge. So better to do it now

359
00:18:00,240 --> 00:18:02,320
Speaker 1: and everybody else when you have the time, rather than

360
00:18:02,359 --> 00:18:04,680
Speaker 1: under the gun when the car breaks when you don't

361
00:18:04,720 --> 00:18:06,800
Speaker 1: want it to. I'm Ronning Andy and the Car Doctor.

362
00:18:06,840 --> 00:18:14,760
Speaker 1: I'll be back right after this. Ron's in the zone,

363
00:18:14,880 --> 00:18:17,800
Speaker 1: the Auto Zone Studio, and he'll be back right after this.

364
00:18:32,600 --> 00:18:36,440
Speaker 1: Welcome back to the Auto Zone Studio. Here's Ron. Hey,

365
00:18:36,480 --> 00:18:39,360
Speaker 1: let's get on over and talk to Mike and Pennsylvania. Mike,

366
00:18:39,400 --> 00:18:42,480
Speaker 1: Welcome back to the Car Doctor, sir. What's going on today?

367
00:18:42,560 --> 00:18:45,600
Speaker 4: Yeah, I appreciate you taking my call. Well, last time

368
00:18:45,640 --> 00:18:47,879
Speaker 4: I called it was a couple of weeks ago and

369
00:18:47,920 --> 00:18:50,760
Speaker 4: I had two issues. I had a misfire on five

370
00:18:50,840 --> 00:18:54,359
Speaker 4: and six and my transmission brought up a code that

371
00:18:54,400 --> 00:18:57,879
Speaker 4: it was slipping, and I had some chatter in it

372
00:18:58,000 --> 00:19:01,600
Speaker 4: going down the road, and I did what you said

373
00:19:01,640 --> 00:19:05,880
Speaker 4: and switched out five and six with seven and eight

374
00:19:06,520 --> 00:19:11,800
Speaker 4: for the misfire and the transmission. I still have the

375
00:19:11,880 --> 00:19:17,080
Speaker 4: chatter on it. The misfire's gone, so I guess it

376
00:19:17,119 --> 00:19:21,080
Speaker 4: was a replaced transmission. So I guess I'm getting another

377
00:19:21,119 --> 00:19:23,320
Speaker 4: transmission at this point into it.

378
00:19:24,240 --> 00:19:27,280
Speaker 1: Yeah, I would agree. I would agree with that. I'm curious, though,

379
00:19:27,400 --> 00:19:30,520
Speaker 1: you know what changed with five and six. That's swapping

380
00:19:30,600 --> 00:19:33,800
Speaker 1: it made it go away. The only thing I can

381
00:19:33,880 --> 00:19:37,280
Speaker 1: think of is this is a coiled what yours is six?

382
00:19:37,920 --> 00:19:40,720
Speaker 1: This is a this is this is a separate coil

383
00:19:40,840 --> 00:19:48,200
Speaker 1: mounted on the valfhol routine. So is the spark plug boot?

384
00:19:48,320 --> 00:19:50,800
Speaker 1: Was the spark plug boot? They were they Delco plugs?

385
00:19:50,800 --> 00:19:52,720
Speaker 1: Do you remember that were in there?

386
00:19:54,359 --> 00:19:55,879
Speaker 4: Yes? I think they were.

387
00:19:55,920 --> 00:19:58,119
Speaker 1: And did they have no did they have no ripple?

388
00:19:58,119 --> 00:20:03,640
Speaker 1: Where they have straight porcelain shank plug? Okay? It may

389
00:20:03,720 --> 00:20:06,560
Speaker 1: have something to do with how the boot was sealed

390
00:20:06,600 --> 00:20:10,959
Speaker 1: against the body of the plug. So if if the

391
00:20:11,119 --> 00:20:15,640
Speaker 1: fault comes back because you disturbed the plug wire, if

392
00:20:15,640 --> 00:20:19,760
Speaker 1: the fault comes back. What I would do is dielectric grease.

393
00:20:19,760 --> 00:20:24,120
Speaker 1: Do you know what dielectric grease is? Put? I would

394
00:20:24,119 --> 00:20:27,280
Speaker 1: put a dab of dielectric grease inside the boot. It

395
00:20:27,320 --> 00:20:29,600
Speaker 1: works as a good boot release agent, but it also

396
00:20:29,760 --> 00:20:33,560
Speaker 1: acts as an insulator and it'll it'll help, it'll help

397
00:20:34,000 --> 00:20:37,320
Speaker 1: trap the spark if it were so. Listen, let's you know,

398
00:20:37,480 --> 00:20:40,879
Speaker 1: electricity takes the path of least resistance, Okay, if it

399
00:20:40,920 --> 00:20:43,800
Speaker 1: can sneak out past the leaky spark plug boot and

400
00:20:43,880 --> 00:20:46,280
Speaker 1: see ground against the body of the plug versus going

401
00:20:46,320 --> 00:20:50,800
Speaker 1: through the electrode, it will. But if using dielectric solves

402
00:20:50,840 --> 00:20:53,639
Speaker 1: it the next time, then I'm going to tell you

403
00:20:53,720 --> 00:20:56,119
Speaker 1: to put a set of wires on this and then

404
00:20:56,640 --> 00:20:57,800
Speaker 1: you know, go find.

405
00:20:58,800 --> 00:21:02,360
Speaker 4: I already ordered, okay, and I was going to put

406
00:21:02,400 --> 00:21:03,960
Speaker 4: them in that. I think I'm going to change out

407
00:21:04,000 --> 00:21:07,480
Speaker 4: the plugs too, because it's such a hass. Will tick, Yeah,

408
00:21:07,480 --> 00:21:08,320
Speaker 4: I have access.

409
00:21:08,480 --> 00:21:10,280
Speaker 1: Yeah, they never made it. Did I ever tell you

410
00:21:10,400 --> 00:21:14,320
Speaker 1: my idea for how we should design vans somewhere somewhere

411
00:21:14,520 --> 00:21:17,080
Speaker 1: I always felt like when it came to van design,

412
00:21:17,600 --> 00:21:20,520
Speaker 1: somewhere about oh, I don't know, six inches in from

413
00:21:20,560 --> 00:21:23,199
Speaker 1: the hinge of the front door. There should be a

414
00:21:23,200 --> 00:21:26,600
Speaker 1: crease and the whole thing tilts forward, so it opens up.

415
00:21:26,640 --> 00:21:29,119
Speaker 1: It opens up like an eighteen wheeler, right up on

416
00:21:29,160 --> 00:21:31,720
Speaker 1: the nose, and then we could work on it there.

417
00:21:31,760 --> 00:21:33,800
Speaker 1: But for some reason it didn't catch. It didn't catch

418
00:21:33,880 --> 00:21:35,840
Speaker 1: up when it was a big idea in Detroit. Something

419
00:21:35,840 --> 00:21:38,000
Speaker 1: about cost. But I'm not worried about cost. I want

420
00:21:38,000 --> 00:21:40,560
Speaker 1: to make it so it can be repaired. But good

421
00:21:40,560 --> 00:21:43,160
Speaker 1: for you, Good for you, I'm glad. I'm glad you're

422
00:21:43,200 --> 00:21:44,720
Speaker 1: on the path, Mike, And I think if you stay

423
00:21:44,720 --> 00:21:46,240
Speaker 1: with it, you'll fix it and you'll be happy.

424
00:21:47,400 --> 00:21:50,800
Speaker 4: Okay, that sounds good. The second issue I have, I'm

425
00:21:50,880 --> 00:21:54,720
Speaker 4: getting a PO fifty on my.

426
00:21:55,200 --> 00:21:59,240
Speaker 1: Two cents here P zero fifty D.

427
00:22:01,119 --> 00:22:02,679
Speaker 4: Boy, I don't know if it's a D or not.

428
00:22:03,320 --> 00:22:09,760
Speaker 1: Piece P zero fifty is a cold start missfire? Oh

429
00:22:09,800 --> 00:22:12,520
Speaker 1: it is, yeah, to my knowledge, P zero fifty it's

430
00:22:12,560 --> 00:22:15,400
Speaker 1: usually a P zero fifty D. Does the engine run

431
00:22:15,480 --> 00:22:16,600
Speaker 1: rough when you first start it?

432
00:22:17,960 --> 00:22:18,800
Speaker 4: No? Not really.

433
00:22:18,920 --> 00:22:20,879
Speaker 1: What makes you think it's a no two centsor fault?

434
00:22:21,640 --> 00:22:26,160
Speaker 4: Well, it has those two two center code coming up

435
00:22:26,160 --> 00:22:29,440
Speaker 4: on it. Maybe I misread it. Maybe I'm not hitting

436
00:22:29,440 --> 00:22:35,280
Speaker 4: the fifty at rate? Oh, yeah, well what about a nine?

437
00:22:36,040 --> 00:22:38,840
Speaker 1: Okay, a P zero? Yeah, now you've got a two

438
00:22:38,880 --> 00:22:43,760
Speaker 1: centsor fault? All right, very very different. You're taking us

439
00:22:43,800 --> 00:22:48,399
Speaker 1: in different directions, so okay, and when does this come up?

440
00:22:48,400 --> 00:22:48,560
Speaker 4: At?

441
00:22:48,560 --> 00:22:50,200
Speaker 1: What? At what temp? At what speed?

442
00:22:51,000 --> 00:22:55,399
Speaker 4: When that's well, that's that's the code that comes up,

443
00:22:55,800 --> 00:23:02,359
Speaker 4: you know, just when I hook up my code reader.

444
00:23:02,640 --> 00:23:05,200
Speaker 1: We'll do it, okay. And you've got to check engine

445
00:23:05,240 --> 00:23:05,560
Speaker 1: light on?

446
00:23:06,960 --> 00:23:07,240
Speaker 4: Great?

447
00:23:07,359 --> 00:23:10,760
Speaker 1: Uh huh okay, yeah, is there anything? Now? Did this

448
00:23:10,840 --> 00:23:12,680
Speaker 1: happen after you did the spark plug work?

449
00:23:14,200 --> 00:23:15,960
Speaker 4: Now it is before it too, all.

450
00:23:16,000 --> 00:23:17,840
Speaker 1: Right, So this is an addition to it. And this

451
00:23:18,000 --> 00:23:23,800
Speaker 1: was a five to three correct, right, five point three

452
00:23:24,280 --> 00:23:26,480
Speaker 1: P zero And this is a P zero.

453
00:23:26,800 --> 00:23:28,680
Speaker 4: No, I'm sorry, that's a that's a six.

454
00:23:28,760 --> 00:23:30,960
Speaker 1: Oh okay, it's a six. So so this is a

455
00:23:30,960 --> 00:23:35,040
Speaker 1: twenty five hundred and this was a P zero fifty nine?

456
00:23:35,080 --> 00:23:35,880
Speaker 2: Did you say.

457
00:23:37,160 --> 00:23:39,680
Speaker 4: P fifty nine? Right?

458
00:23:40,160 --> 00:23:44,639
Speaker 1: Okay? And what have you done to diagnose it?

459
00:23:46,480 --> 00:23:48,920
Speaker 4: I just put a OBT reader.

460
00:23:48,640 --> 00:23:52,280
Speaker 1: On it, okay, because this could have you know, this

461
00:23:52,320 --> 00:23:54,920
Speaker 1: could just have plain and simpleness, could have a bad

462
00:23:54,960 --> 00:23:57,800
Speaker 1: oh two censor. This is bank two centsor one. This

463
00:23:57,880 --> 00:24:03,240
Speaker 1: is the heater serve. So right right, you know what

464
00:24:03,480 --> 00:24:06,080
Speaker 1: sort of diagnostic equipment do you have, Mike, do you

465
00:24:06,160 --> 00:24:08,159
Speaker 1: have digital vault a meter? Do you have a clamp

466
00:24:08,200 --> 00:24:08,760
Speaker 1: on ant meter?

467
00:24:10,680 --> 00:24:10,880
Speaker 4: Yes?

468
00:24:11,920 --> 00:24:14,439
Speaker 1: Okay, because what you could do is you could measure

469
00:24:14,640 --> 00:24:18,080
Speaker 1: a heater current draw on that Bank two sensor to

470
00:24:18,160 --> 00:24:20,159
Speaker 1: see what it is when you you know, first started.

471
00:24:20,119 --> 00:24:22,280
Speaker 1: You'd have to do it from a cold start, or

472
00:24:22,720 --> 00:24:25,720
Speaker 1: if you want to do this simple, you could verify

473
00:24:25,880 --> 00:24:29,320
Speaker 1: see if the O two sensor between Bank one and

474
00:24:29,359 --> 00:24:31,080
Speaker 1: Bank two are the same and swap them if you

475
00:24:31,080 --> 00:24:34,240
Speaker 1: can get them out of the pipe. Okay, this is

476
00:24:34,640 --> 00:24:37,800
Speaker 1: this is this is downstream. Oh two. If the problem

477
00:24:37,920 --> 00:24:42,959
Speaker 1: stays on Bank two after you swap the sensor, then

478
00:24:43,040 --> 00:24:47,359
Speaker 1: it's wiring or PCM. If it's becomes a Bank one

479
00:24:48,320 --> 00:24:52,680
Speaker 1: sensor two, I'm sorry, Bank one sensor one fault, then

480
00:24:52,920 --> 00:24:55,240
Speaker 1: it's the sensor that you just swapped over.

481
00:24:57,359 --> 00:24:59,720
Speaker 4: Just exchange that right now.

482
00:24:59,760 --> 00:25:01,040
Speaker 1: If you I wanted to get if you wanted to

483
00:25:01,040 --> 00:25:04,800
Speaker 1: get fancy and do this, you could measure amperage on

484
00:25:04,840 --> 00:25:07,080
Speaker 1: the heater control circuit going to that how many miles

485
00:25:07,119 --> 00:25:07,600
Speaker 1: are on this.

486
00:25:08,680 --> 00:25:09,880
Speaker 4: One hundred and fifty?

487
00:25:10,119 --> 00:25:12,080
Speaker 1: Yeah, it's probably time to put to it's probably time

488
00:25:12,119 --> 00:25:14,199
Speaker 1: to put four h two is in it. But you know,

489
00:25:14,280 --> 00:25:16,320
Speaker 1: if we want to diagnose, I like to diagnose and

490
00:25:16,400 --> 00:25:19,760
Speaker 1: learn while we can. So you know, you're do the swapper,

491
00:25:19,840 --> 00:25:20,920
Speaker 1: do the control test.

492
00:25:21,119 --> 00:25:24,560
Speaker 4: Go ahead. I did get the voltage reading on it

493
00:25:24,600 --> 00:25:28,119
Speaker 4: and on the UH bank one sensor it was point

494
00:25:28,119 --> 00:25:32,080
Speaker 4: oh three to point eighty five and I compared it

495
00:25:32,119 --> 00:25:34,720
Speaker 4: to the bank two and it was point two nine

496
00:25:35,320 --> 00:25:36,680
Speaker 4: to point five five.

497
00:25:37,160 --> 00:25:40,040
Speaker 1: Well, so you're looking at you're looking at it on

498
00:25:40,080 --> 00:25:43,960
Speaker 1: the scan tool right right right now? How many other

499
00:25:44,040 --> 00:25:46,119
Speaker 1: let me let me make a point here, all right,

500
00:25:46,160 --> 00:25:48,560
Speaker 1: And I'm not saying that doesn't tell me something, but

501
00:25:48,760 --> 00:25:51,679
Speaker 1: this is a this is typically a problem with the

502
00:25:51,680 --> 00:25:57,199
Speaker 1: heater circuit, not an activity fault. All right, So you

503
00:25:57,200 --> 00:26:00,159
Speaker 1: know how many other PIDs? How many other pieces of

504
00:26:00,200 --> 00:26:02,280
Speaker 1: information do you have on that scan tool while you're

505
00:26:02,280 --> 00:26:09,960
Speaker 1: looking at O two sensor activity full screen? Twenty? Okay?

506
00:26:10,520 --> 00:26:11,240
Speaker 4: I think twenty?

507
00:26:11,440 --> 00:26:13,040
Speaker 1: Okay? Do you have a do you have you have

508
00:26:13,040 --> 00:26:15,760
Speaker 1: a Windows computer or an Apple computer? You got a

509
00:26:15,760 --> 00:26:19,720
Speaker 1: computer in the house right right, How fast does that

510
00:26:19,760 --> 00:26:22,000
Speaker 1: computer work if you open up twenty five Windows at

511
00:26:22,000 --> 00:26:24,240
Speaker 1: a time versus three?

512
00:26:25,000 --> 00:26:26,159
Speaker 4: Good point?

513
00:26:26,359 --> 00:26:31,199
Speaker 1: Okay? So if you want to measure two sensors and

514
00:26:31,240 --> 00:26:34,080
Speaker 1: you can see this sometimes depending upon the scan tool,

515
00:26:34,760 --> 00:26:37,520
Speaker 1: if you have the ability to tag. Like if I'm

516
00:26:37,600 --> 00:26:40,040
Speaker 1: going out to do a volumetric efficiency test, which is

517
00:26:40,080 --> 00:26:44,080
Speaker 1: a measurement of how an engine breathe, look, I look

518
00:26:44,119 --> 00:26:52,280
Speaker 1: at RPM, intake air tim sensor, okay, rpm intake AIRTIMP censor,

519
00:26:52,560 --> 00:26:55,840
Speaker 1: barometric pressure, and I'll go out and I'll do a

520
00:26:55,880 --> 00:26:58,719
Speaker 1: full throttle pull and I'll come back and i'll plug everything. Oh,

521
00:26:58,760 --> 00:27:02,280
Speaker 1: in mass airflow calculation, I look at those four. Sometimes

522
00:27:02,320 --> 00:27:03,840
Speaker 1: I don't even look at barrel because I'll just do

523
00:27:03,880 --> 00:27:07,120
Speaker 1: a barrel by me Google search and I'll do a measurement.

524
00:27:07,240 --> 00:27:10,200
Speaker 1: If I do a volumetric efficiency test as we as

525
00:27:10,240 --> 00:27:13,399
Speaker 1: we call it, and I bring up all thirty PIDs,

526
00:27:14,280 --> 00:27:17,720
Speaker 1: it's amazing how slow everything is because it just starts

527
00:27:17,760 --> 00:27:21,679
Speaker 1: to draw like a tired at your sketch. You know,

528
00:27:21,920 --> 00:27:26,080
Speaker 1: it just it just goes much slower. So just just

529
00:27:26,119 --> 00:27:26,600
Speaker 1: be aware.

530
00:27:27,280 --> 00:27:30,360
Speaker 4: You know I did. I did the barometric on it,

531
00:27:30,400 --> 00:27:33,640
Speaker 4: and I got like ten the inches in the map

532
00:27:33,720 --> 00:27:37,639
Speaker 4: center I got point map yeah airplow, I got point

533
00:27:37,720 --> 00:27:38,520
Speaker 4: seven to seven.

534
00:27:39,200 --> 00:27:41,560
Speaker 1: So you can do this. You can do calculated load.

535
00:27:41,600 --> 00:27:43,240
Speaker 1: I'll tell you. Let me pull over and take this pause.

536
00:27:43,280 --> 00:27:45,520
Speaker 1: When I come back, I'll tell you real quick how

537
00:27:45,520 --> 00:27:47,720
Speaker 1: you can do a calculated load test using your scan tool.

538
00:27:47,720 --> 00:27:49,520
Speaker 1: Don't go away, I'm running ending of the car doctor.

539
00:27:49,520 --> 00:28:06,639
Speaker 1: We'll be back right after this. Welcome back. We're talking

540
00:28:06,880 --> 00:28:10,119
Speaker 1: with Mike and Pa and the six GMC. Mike, you're

541
00:28:10,160 --> 00:28:13,720
Speaker 1: still there, yes, So let's talk about two tests you

542
00:28:13,760 --> 00:28:15,919
Speaker 1: can do. I'll actually talk to you about ve also,

543
00:28:16,280 --> 00:28:20,040
Speaker 1: so calculated load. Let's start there, calculated load. Both of

544
00:28:20,040 --> 00:28:22,840
Speaker 1: these are about how well does an engine breathe? And

545
00:28:23,280 --> 00:28:28,320
Speaker 1: we've incorporated both of these into our everyday diagnostic driveability

546
00:28:28,320 --> 00:28:30,239
Speaker 1: tests just because we want to know what no one

547
00:28:30,240 --> 00:28:32,879
Speaker 1: good is. One of the neat things about or one

548
00:28:32,920 --> 00:28:35,280
Speaker 1: of the things to be aware about with volumetric efficiency

549
00:28:35,359 --> 00:28:38,040
Speaker 1: is it will change on a variable valve timing engine

550
00:28:38,040 --> 00:28:40,920
Speaker 1: and turbo charge and supercharged engines, So there is some

551
00:28:41,400 --> 00:28:44,280
Speaker 1: there is some changes that you have to be aware of,

552
00:28:44,280 --> 00:28:46,560
Speaker 1: but you've got to get the foundation of it. So

553
00:28:47,120 --> 00:28:49,760
Speaker 1: both of these tests are about how well does an

554
00:28:49,800 --> 00:28:53,080
Speaker 1: engine breathe because at the basic root of it all,

555
00:28:53,200 --> 00:28:55,520
Speaker 1: an engine is just a big air pump, air in,

556
00:28:55,800 --> 00:28:59,080
Speaker 1: air out, Okay, and you know the best example I

557
00:28:59,160 --> 00:29:01,880
Speaker 1: could give is if you were a runner, is for

558
00:29:01,960 --> 00:29:04,280
Speaker 1: you to go out and run your best quarter mile

559
00:29:04,880 --> 00:29:07,120
Speaker 1: and then put a mask on and run that quarter mile.

560
00:29:07,400 --> 00:29:09,120
Speaker 1: It would be harder, right, It would be harder for

561
00:29:09,160 --> 00:29:11,040
Speaker 1: you to breathe in through your nose, out through your mouth,

562
00:29:11,080 --> 00:29:13,400
Speaker 1: that kind of thing, because you're covering your intake and

563
00:29:13,440 --> 00:29:16,360
Speaker 1: you're exhaust. So what we want to do is we

564
00:29:16,400 --> 00:29:19,280
Speaker 1: want to measure calculated load. First. Calculated load is easy.

565
00:29:19,680 --> 00:29:21,960
Speaker 1: You know, I would tell you to bring up RPM.

566
00:29:22,280 --> 00:29:25,640
Speaker 1: There will be a mass airflow value on your scan

567
00:29:25,760 --> 00:29:28,920
Speaker 1: tool and a calculated load pit. This is all under

568
00:29:28,960 --> 00:29:33,760
Speaker 1: OBD two, all right, not not your make model. All right.

569
00:29:33,800 --> 00:29:35,320
Speaker 1: You want to look at cool and temp. You want

570
00:29:35,320 --> 00:29:37,040
Speaker 1: to look at intake air temp. That's up to you.

571
00:29:37,080 --> 00:29:39,920
Speaker 1: Those those first three are the important ones, and basically

572
00:29:40,040 --> 00:29:42,120
Speaker 1: you're gonna bring those up. You're gonna find a quiet,

573
00:29:42,720 --> 00:29:46,520
Speaker 1: flat stretch of roads, kind of deserted, and from ten

574
00:29:46,560 --> 00:29:48,360
Speaker 1: miles an hour, you're gonna kick it and put your

575
00:29:48,360 --> 00:29:50,800
Speaker 1: head through that, put your put your foot through the headlight.

576
00:29:51,320 --> 00:29:52,720
Speaker 1: All right. You want to put it to the floor,

577
00:29:52,720 --> 00:29:55,640
Speaker 1: wind it out and see what calculated goes. Calculated load

578
00:29:55,680 --> 00:29:58,160
Speaker 1: goes to this is great. If you have a graphic

579
00:29:58,280 --> 00:30:01,880
Speaker 1: scan tool, all right, you and see the peak a

580
00:30:02,080 --> 00:30:08,680
Speaker 1: typical good well breathing non VVT, non supercharged triper charged engine,

581
00:30:08,800 --> 00:30:11,840
Speaker 1: you will see somewhere in the ninety percent tile of

582
00:30:11,920 --> 00:30:17,200
Speaker 1: calculated load. That is a mathematical engineering measurement equation of

583
00:30:17,720 --> 00:30:19,960
Speaker 1: how that engine is breathing, how much air it's able

584
00:30:20,040 --> 00:30:24,840
Speaker 1: to pull across that mass airflow sensor. All right, as

585
00:30:24,880 --> 00:30:28,040
Speaker 1: a starting point, you have a six liter engine in

586
00:30:28,080 --> 00:30:32,120
Speaker 1: your GMC. So the reason I want you to bring

587
00:30:32,200 --> 00:30:36,080
Speaker 1: up the mass airflow PID is because ad idle, if

588
00:30:36,120 --> 00:30:39,360
Speaker 1: you are looking at grahams per second, you will typically

589
00:30:39,440 --> 00:30:42,720
Speaker 1: see about six grams per second coming across that mass

590
00:30:42,720 --> 00:30:46,959
Speaker 1: airflow's that's pretty much standard on all engines modifying, you know,

591
00:30:47,360 --> 00:30:49,520
Speaker 1: not counting for the way we change some of the

592
00:30:49,520 --> 00:30:52,719
Speaker 1: breathing cycles, all right, VVT and so on. So if

593
00:30:52,760 --> 00:30:54,440
Speaker 1: I saw a five point an, I'm okay with that.

594
00:30:54,480 --> 00:30:56,320
Speaker 1: If I six six point two, I'm okay with that.

595
00:30:56,600 --> 00:30:58,800
Speaker 1: If I saw a four point five, I'm not so

596
00:30:58,920 --> 00:31:01,240
Speaker 1: okay with that. If I saw a seven point nine,

597
00:31:01,240 --> 00:31:02,960
Speaker 1: I'm not so okay with that. I know right off

598
00:31:03,000 --> 00:31:05,960
Speaker 1: the bat I'm starting out wrong. So my calculated load

599
00:31:05,960 --> 00:31:10,720
Speaker 1: measurement is going to be wrong also, all right, Once

600
00:31:10,760 --> 00:31:15,240
Speaker 1: you master that, then we can go into volumetric efficiency.

601
00:31:15,320 --> 00:31:19,560
Speaker 1: Volumetric efficiency is a much more detailed analysis. It's kind

602
00:31:19,560 --> 00:31:22,840
Speaker 1: of like doing calculated load on steroids. If you go

603
00:31:22,960 --> 00:31:27,080
Speaker 1: out to the web and Google search Automotive Training group

604
00:31:27,240 --> 00:31:34,320
Speaker 1: atg space V Calculator, it will bring you to their

605
00:31:34,440 --> 00:31:38,719
Speaker 1: web page that explains ve in much better detail than

606
00:31:38,760 --> 00:31:41,160
Speaker 1: time permits me to do so here. Plus it will

607
00:31:41,200 --> 00:31:45,080
Speaker 1: give you the calculator, the actual you know, plugging your

608
00:31:45,160 --> 00:31:49,120
Speaker 1: numbers to give you your VEE. And now you can

609
00:31:49,160 --> 00:31:52,000
Speaker 1: go and do this so you know what. And again,

610
00:31:52,200 --> 00:31:54,600
Speaker 1: diagnostics is about what's what's good, So I can tell

611
00:31:54,640 --> 00:31:56,880
Speaker 1: you what's bed. If you get in the habit of

612
00:31:56,920 --> 00:32:00,640
Speaker 1: doing ve and calculated load on everyone of your cars

613
00:32:00,680 --> 00:32:03,160
Speaker 1: and you write your numbers down, you'll know what you got.

614
00:32:03,160 --> 00:32:05,360
Speaker 1: So when the car starts to fail and have a problem,

615
00:32:05,600 --> 00:32:07,560
Speaker 1: you'll be able to figure it out much easier because

616
00:32:07,600 --> 00:32:09,400
Speaker 1: you know it's not breathing. You know it's not this.

617
00:32:09,520 --> 00:32:11,840
Speaker 1: You know it's not that you switch things around, just

618
00:32:11,880 --> 00:32:14,280
Speaker 1: like you do with the spark plugs. Keep me updated, Michael,

619
00:32:14,200 --> 00:32:15,440
Speaker 1: I want to know what the end result is and

620
00:32:15,480 --> 00:32:17,240
Speaker 1: I enjoy. I hope you enjoy many more years in

621
00:32:17,280 --> 00:32:19,320
Speaker 1: your vehicle. I'm Ronning Anie in the car doctor. I'll

622
00:32:19,360 --> 00:32:33,120
Speaker 1: be back right after this. Let's get right to it,

623
00:32:33,200 --> 00:32:35,280
Speaker 1: ron An Anie and at your service, Steven Delaware in

624
00:32:35,360 --> 00:32:37,280
Speaker 1: ninety four one fifty. What's going on, kiddo?

625
00:32:38,760 --> 00:32:42,480
Speaker 2: Hey, thanks to taking my call, ron Wilcome. This is

626
00:32:42,480 --> 00:32:45,600
Speaker 2: a you've heard about this one before. This is the

627
00:32:45,600 --> 00:32:48,960
Speaker 2: one I had the issue with the odometer spedometer okay,

628
00:32:49,000 --> 00:32:51,760
Speaker 2: which was repaired by some guys in Texas did a

629
00:32:51,800 --> 00:32:56,520
Speaker 2: good job. Well. Subsequent to that, I drive it every

630
00:32:56,960 --> 00:32:59,720
Speaker 2: my neighbors truck. Actually I drive it, try to do

631
00:32:59,720 --> 00:33:02,080
Speaker 2: it every every week when I if I depend. But

632
00:33:02,600 --> 00:33:06,640
Speaker 2: it developed an issue where the blinkers didn't work, and

633
00:33:06,680 --> 00:33:09,840
Speaker 2: then you know, I played with the multi function switch

634
00:33:09,960 --> 00:33:14,200
Speaker 2: and they worked, and long story short, took the tran

635
00:33:14,160 --> 00:33:18,840
Speaker 2: inspection and everything blinkers worked and everything past except the

636
00:33:19,480 --> 00:33:26,120
Speaker 2: brake light. Okay, what So I went back and I

637
00:33:26,200 --> 00:33:28,520
Speaker 2: got to have to have to do with the cluster,

638
00:33:28,640 --> 00:33:31,040
Speaker 2: and I took it apart and receded, checked everything blah

639
00:33:31,080 --> 00:33:36,640
Speaker 2: blah blah, and it didn't do anything. So I went

640
00:33:36,680 --> 00:33:40,640
Speaker 2: down and I happened to have a diagram electrical diagram,

641
00:33:40,720 --> 00:33:43,840
Speaker 2: and went to a few I think you's thirteen. Ye,

642
00:33:44,000 --> 00:33:46,560
Speaker 2: it had power all the time, checked it, Yep, it

643
00:33:46,640 --> 00:33:47,280
Speaker 2: had power.

644
00:33:47,680 --> 00:33:50,840
Speaker 1: And so let's let's cut to the chase. Do you

645
00:33:50,840 --> 00:33:52,240
Speaker 1: did you go to the brake light switch? Do you

646
00:33:52,240 --> 00:33:53,960
Speaker 1: have power on the light green? Red? Going into the

647
00:33:53,960 --> 00:33:54,720
Speaker 1: break light switch?

648
00:33:55,880 --> 00:33:56,280
Speaker 2: I do?

649
00:33:56,400 --> 00:33:58,120
Speaker 1: Okay? Do you have power coming out if you push

650
00:33:58,160 --> 00:33:59,600
Speaker 1: the switch? If you push the pedal down?

651
00:34:01,040 --> 00:34:03,640
Speaker 2: Well, I pushed the pedal, I did that when I

652
00:34:03,760 --> 00:34:06,920
Speaker 2: was checking for a continuity. I didn't. I didn't actually

653
00:34:06,920 --> 00:34:08,520
Speaker 2: do it with test light.

654
00:34:08,760 --> 00:34:13,440
Speaker 1: Okay, so let's do that. All right. So continuity was good,

655
00:34:13,480 --> 00:34:15,879
Speaker 1: but is it enough? Is there a high resistance? Will

656
00:34:15,880 --> 00:34:18,080
Speaker 1: it carry the electrical load? Let's come out of the

657
00:34:18,160 --> 00:34:21,360
Speaker 1: multifunction switch? Well, then you know, do we have a

658
00:34:21,360 --> 00:34:23,680
Speaker 1: bad break light switch? All right? I mean, let's make

659
00:34:23,719 --> 00:34:27,279
Speaker 1: this simple. Okay, let's go to the listen, just for giggles,

660
00:34:27,640 --> 00:34:30,080
Speaker 1: get somebody to depress the brake light switch and go

661
00:34:30,160 --> 00:34:33,680
Speaker 1: back to the bulb socket. Could we possibly have two

662
00:34:33,760 --> 00:34:36,759
Speaker 1: burnt out break light bulbs? Check for power back there,

663
00:34:37,160 --> 00:34:39,000
Speaker 1: all right, and then work your way forward. Come to

664
00:34:39,040 --> 00:34:42,160
Speaker 1: the other side of the multifunction switch and verify power

665
00:34:42,160 --> 00:34:44,520
Speaker 1: on the light green, orange and the orange light blue.

666
00:34:44,680 --> 00:34:47,680
Speaker 1: Don't assume because the multifunction switch was giving you problems

667
00:34:47,760 --> 00:34:51,040
Speaker 1: prior that that could be the cause, but it could

668
00:34:51,040 --> 00:34:53,240
Speaker 1: be somewhere else. You're gonna have to verify what's good

669
00:34:53,400 --> 00:34:55,160
Speaker 1: to find out what's bad. Call me back when you

670
00:34:55,200 --> 00:34:56,919
Speaker 1: know more. I'm on an ady in the car. Doctor.

671
00:34:57,040 --> 00:35:06,080
Speaker 1: The mechanics aren't expensive, they're priceless. See you, Jas,
