Welcome to the Automotive Diagnostic Podcast.
00:14
We're going to explore ways to sharpen our diagnostic skills, find learning resources, and hear from
00:20
experts in the automotive field.
00:24
Hey, have you ever been faced with the challenge of sourcing, installing, and programming a used
00:33
control module in a vehicle?
00:35
I know a lot of us have.
00:37
It seems to be happening more and more often today with the volume of control modules on
00:42
vehicles, the cost of some new ones, or even the availability of new control modules.
00:47
In some cases, used may be the only option.
00:50
So what do you do here?
00:51
I strongly recommend checking out SJ Auto Solutions and Tommie Oliva.
00:57
Tommie offers a cloning service for used control modules to make these things plug and play
01:04
for the vehicle that you're working on.
01:06
In a lot of cases, he is also able to source the control modules if you're unable to
01:11
locate one for the vehicle that you're working on.
01:14
But once you get connected with Tommie, he's going to offer fantastic support from
01:19
Start to Finish to make sure that that control module is going to work in your application.
01:25
He's also got tech support that he offers through his website, along with some free resources
01:31
there as well on information about used control module programming.
01:37
So make sure to check out SJ Auto Solutions.
01:40
I can't recommend that enough.
01:43
Hey, what's going on?
01:47
Welcome to another episode of the Automotive Diagnostic Podcast.
01:50
My name is Sean Tipping, and I'll be your host once again for this week's episode.
01:54
Thank you so much for joining me.
01:55
I got just me on the show this week.
01:58
We are going to have a guest on for next week's episode.
02:01
But today, I want to talk about a car that I diagnosed this week.
02:06
But it's also a throwback to July of 2020.
02:11
I had just started this podcast.
02:13
It was episode number 28.
02:15
I did a case study on a 2016 Chevrolet Cruze with a 1.4 liter turbo that had some really
02:24
And it was an interesting fix.
02:26
If you haven't been listening to the show for that long, maybe you haven't heard
02:30
This is going to be all new information to you.
02:32
If you have been listening for a long time, it's been a while.
02:35
I actually had to pull up the episode and listen to it to hear all the details.
02:40
As it turns out, the symptoms that I had on the car this week were exactly the same, like
02:47
A different car, slightly, but same era and same problem, although this one was a little
02:54
bit of a different scenario.
02:57
So first off, if you want to check out the earlier episode, again, episode 28, I'll
03:02
put the link in the show notes.
03:04
This was pretty early on, but I walked through how I found the problem and it was actually
03:09
an IETN post that got me there.
03:12
I was kind of lost and maybe I would have found it eventually, but it would have taken me a
03:17
lot longer than it did because someone else had already gone through the work.
03:22
But maybe I can be that for you now.
03:25
So anyways, what it ended up being on that Chevy Cruze was that the shop had just swapped
03:30
the motor and they had the wrong crankshaft sensor in there.
03:34
Now that sounds easy enough to diagnose.
03:36
We've seen problems like that on cars before where the wrong sensor gets put in.
03:42
There's maybe two different crankshaft reluctors that could be used in one application.
03:50
There's like a mid-year split and the engine will bolt in, but the pattern is different
03:55
between the two engines.
03:56
And so if you don't get that correct, well, the computer's not going to start the
04:02
We've seen that across different brands even on a, what was the one recently, there was a
04:07
Ford engine that was installed and they put the crankshaft reluctor in, but there was a
04:13
switch between a VR two-wire sensor and a Hall Effect sensor in that year range and
04:21
they got the wrong one.
04:22
So it was outputting a signal.
04:23
If you scoped it, you saw a pattern, but it wasn't right.
04:26
The computer wasn't expecting that.
04:28
It was looking for something completely different.
04:30
And so it wasn't going to start from that.
04:33
Now there was some harness stuff that was messed up on that one too, but anyways, we see these
04:38
Missing tone wheels, that's another one where, you know, that sandwiched in between the
04:43
crankshaft and the flex plate and oops, we forgot to put it on there.
04:48
That's going to be an issue.
04:49
Again, just wrong sensor, bad sensor.
04:52
We get these things with engine swaps, but this one was a little bit stranger.
04:57
So I'm going to walk you through the symptoms here.
04:59
And I should probably set up the vehicle that I'm actually working on this week.
05:03
It was a 2017 Chevrolet Malibu with a 1.5 liter turbo.
05:10
So different engine, although the same family of cars, it's a 16 to a 17 and a 1.4 turbo
05:19
and a 1.4 turbo to a 1.5 turbo.
05:23
So a little bit of a difference there.
05:25
It's not like the parts are interchangeable between the two engines, but again, it's kind
05:30
of the same era and family of vehicles.
05:33
So what I'm dealing with on this Malibu, and again, this is mirror image of the cruise
05:41
So the symptoms could just be transferred over to one, but I'm going to list through
05:44
what I was experiencing on this vehicle.
05:47
And it took me a minute to remember like the grouping of symptoms together was exactly
05:53
the same as the thing I dealt with.
05:55
As I was going through it, I'm like, something really seems familiar about this.
05:59
I remember, you know, this exact grouping of symptoms happening on another car.
06:05
And that's when I looked back in my notes and I was like, oh, that's right.
06:07
I got to look for a blank.
06:09
Here's what it was doing.
06:10
Here's why it's weird because this is a very strange combination of problems to
06:16
have no codes present anywhere in the vehicle indicating that there is something wrong
06:22
when there clearly is something wrong.
06:24
So first thing, the engine will start and run now.
06:28
It's strange the way that it does it in this application.
06:31
And this first one, actually, I don't recall on the Chevy cruise that I did.
06:36
So maybe there is a slight difference here, but I'm going off of what I saw
06:40
this week, maybe I did not note this detail back in 2020.
06:45
But when you went to start it, the engine would start.
06:49
However, this is a push button vehicle.
06:52
When you would release the push button, you could still hear the starter
06:57
dragging against the flex plate, the teeth on the flex plate.
07:03
Like it was still halfway engaged or like the drive pinion was still
07:10
rotating along with the flex plate, which it should not be once I release
07:15
that button. And, you know, now that I say that out loud,
07:17
I wonder if the cruise was a blade style key.
07:22
This was a push button.
07:23
Again, don't know that for sure, but I don't recall a starter dragging being the
07:27
issue, but this one was.
07:28
And then if you would hit the button again, the start button on the dash
07:32
for this Malbu, then it would stop, but the engine would continue to run.
07:36
OK, so then at that point, your engine is running and everything
07:40
seemingly OK at first, except for there is no power steering.
07:46
And this is electric steering.
07:48
Other things, and these take a little bit more work to notice that this is
07:52
the case, but I'm giving you a listing of symptoms that you can find on a car.
07:56
You can add these things up and you can say, I know exactly where to go.
08:00
So the other things that occur on the vehicle are you have no power steering.
08:05
The charging system does not work, or at least it doesn't charge
08:10
up to the level it's supposed to.
08:12
I didn't sit there long enough to see if the battery would discharge
08:17
completely, but it would sit at about 12 volts the entire time.
08:21
So I don't know if the alternator was doing anything.
08:23
I don't think it was, but it definitely wasn't charging where it needed to be.
08:27
It was at, you know, 12 volts, which was to be up over 14.
08:31
But we have no warning lights, we have no codes.
08:34
And on the cruise, I had mentioned, if you unplug the alternator
08:38
in that application, it would start, it would fall field and it would charge.
08:42
So the alternator was capable.
08:44
And funny enough on this Malbu, when I got to the shop,
08:46
they had been working on it for a while was the alternator had already been replaced.
08:51
So somebody had gone down that route.
08:54
I think they didn't mention that to me, but somebody had put a brand new
08:58
alternator in there, probably trying to fix this charging issue.
09:01
And when I looked at this, the cruise back in 2020, I thought that was my issue.
09:07
I'm like, Oh, okay.
09:08
Well, this is why the power steering doesn't work is because the system
09:13
voltage is not where it needs to be.
09:14
Well, turns out that is not the case.
09:17
There are other electrical signs on the vehicle as well.
09:19
The rear defrost and if it's equipped with heated seats, those do not operate.
09:25
You can press the button.
09:28
It does not allow you to operate those components.
09:31
And there is an idle surge.
09:33
So every 34 30 to 40 seconds, you would see the idle surge up, come back down.
09:40
Um, finally on this Malbu, if you were to put the transmission into gear,
09:46
then the engine would stall, but if you left it in park, it would run all
09:49
day long with a little idle surge here and there.
09:52
Um, but that would be it.
09:53
And again, scan it, no codes at all.
09:56
You can do this every single time.
09:58
And I tried to get a little history on the vehicle for this one to see, like,
10:02
had you guys, you know, done anything.
10:03
They didn't mention the alternator, like I said, um, but they did say
10:07
when the car had originally come in, what they ended up finding was
10:13
Now again, this is a 1.5 liter and we have seen this many times where
10:18
the camshaft for the intake would break on the end.
10:23
Um, and so you would actually get a rotating camshaft enough to
10:28
where the engine runs.
10:30
Maybe you lose one cylinder.
10:31
Maybe you don't, depending on where the camshaft breaks, but it's
10:36
not moving the part of the camshaft that, uh, has the camshaft
10:43
So you get a camshaft sensor code.
10:45
If you put a boroscope down in there, you can see that the, the
10:48
camshaft's broken and this is what they ended up finding on this one.
10:51
Five does happen on these.
10:53
They replaced the camshaft.
10:54
Um, but I have a feeling along the way they replaced another
10:58
component that they didn't mention and I'll get to that.
11:01
Um, cause that was what fixed this one.
11:04
Um, but that was the history.
11:07
Now I asked them, I was like, did this thing run, you know,
11:09
properly before this happened and they weren't sure they assume that it was,
11:15
but the customer brought it into them in a non running state.
11:19
So they never saw it run beforehand.
11:21
So anyways, who did what, uh, hard to say, but it's on me to figure it out.
11:25
But luckily I have this in my memory and I do have some stuff recorded
11:31
in a podcast forum.
11:32
This was before I did my, uh, like vehicle database notes that I
11:37
do pretty religiously now, um, like this event this week went into
11:42
there with all the details so that if this ever pops up again, myself
11:47
and my whole team have access to, to the combination of symptoms and
11:50
we go right to it and okay, it's podcast episode two.
11:54
So you can find it that way.
11:55
So what I ended up finding on this one, and I'm going to give you
11:59
my thoughts on it and I'm going to give you a real practical way to
12:03
identify that this is the problem.
12:05
Like if you run into it.
12:06
Now you might be the one working on it and that makes it a little
12:08
easier because you know exactly what you did or didn't do, but maybe
12:11
you're doing mobile, maybe you're taking care of this for someone else.
12:15
Uh, you've stepped into the situation after repairs have been done
12:18
like myself and you need to get to the solution quickly.
12:22
I'll give you a very practical, realistic way to determine that
12:27
this is your issue very quickly with very little testing.
12:32
Um, but what the issue is the crankshaft sensor on these vehicles.
12:38
Now, um, these are both auto stop, start vehicles, right?
12:42
They have the ability to shut off at a stop.
12:44
Um, when you put your foot on the brake, you lift your foot off
12:47
the brake and then it should restart and then you can start driving.
12:51
Now in the, uh, instance of the cruise back in 2020, there was
12:57
an option for that one for to either have, uh, auto stop, start
13:01
or not in the same like vehicle platform.
13:05
It depends on the trim level and what it was ordered.
13:07
Uh, the RPO code is KL nine.
13:10
Uh, if you're looking those up, you can tell if it's equipped or not.
13:12
You can look at the dashboard too, um, because there'll be a section
13:16
of the tachometer that has, uh, auto stop at the bottom.
13:20
If it's not equipped with that, you won't see that on the dash,
13:23
but you can look for that KL nine, uh, RPO code as well.
13:27
In the case of this Malibu this week, it did not appear to be an option.
13:32
Um, now I could be wrong, but from what I found, uh, especially looking
13:37
up parts that the 17 Malibu came only all 17 Malibus with this one five
13:45
came with the auto stop, start.
13:47
So you didn't have an option to not have this.
13:50
And that's the KL nine RPO code too.
13:53
Um, which makes it just a little bit more confusing, but the
13:58
crankshaft sensor is different for the Chevy cruise, depending on
14:04
if you have auto stop starter or if you don't, there's two different part
14:08
So you can look this up on a 17 cruise with one four again, Malibu only lists
14:13
one, but what happened in the Chevy cruise was the shop had just changed
14:20
out the motor and when they changed the motor, they left the crankshaft
14:26
sensor in the donor engine as it was delivered to them, right?
14:30
They get an engine.
14:31
It's got a crankshaft sensor bolted into the block.
14:33
They throw that into the car and just plug it in and they go.
14:37
And then they have this problem after they get everything back together.
14:40
And that's where I went through and I found out and then I asked them,
14:43
I'm like, did you change the crankshaft sensor?
14:45
They said, no, so I was like, well, let's put in the original one.
14:50
All of the problems are gone.
14:53
So fast forward to now.
14:54
I'm thinking the same thing that, oh, okay.
14:57
You know, maybe there's an option for, um, auto stop versus not.
15:03
Again, it turns out there isn't.
15:06
And I was considering the work that they told me they did there.
15:08
They said they did a camshaft, not anything with a crankshaft, but this
15:14
show was brought to you by auto rescue tools and Isaac Rodel.
15:17
If you've been looking for a programming laptop, you're not sure which one to buy
15:23
or how to set it up, especially if you want to program multiple brands.
15:29
You know, you've got some domestic vehicles.
15:31
You've got your European vehicles.
15:33
Can the same software go on the same laptop?
15:36
What size hard drive do I need?
15:38
All those questions.
15:40
He can custom set up programming laptops that are ready to tackle any
15:47
I've got one of these laptops myself and I can say that it is outstanding.
15:51
And it really streamlines the process by having everything you need in one device.
15:57
So if you're looking for something like that, I highly recommend checking
16:01
out auto rescue tools.com.
16:03
You'll also find scan tools, diagnostic equipment, key cutting
16:07
equipment and much more.
16:09
Check out the link in the show notes.
16:11
I highly recommend it.
16:13
I use my phone and I reach down the backside of the motor and right underneath
16:18
the starter, you can't see it from the top.
16:20
But again, I just use the four or the like self facing camera on my phone.
16:26
I stuck it down in there with a light and I could see the crankshaft sensor.
16:29
You can reach it and touch it.
16:32
If you just reach below the starter with your hand, but I could see with my
16:36
phone, I could see is a brand new crankshaft sensor that's bolted up into
16:41
And so this is a, you know, eight year old vehicle.
16:45
You can definitely tell if the sensor is brand new or if it's been in there
16:48
for a while, this one's brand new.
16:50
And so that immediately, once I connected all the dots of the
16:53
symptoms that were going on, um, I knew that, okay, this is, we're
16:58
dealing with the same thing here.
16:59
Now, again, I'm not sure where this particular crankshaft sensor came
17:04
from or why it was changed, but odds are it's wrong.
17:08
So I'll get to the practical way that you can prove this out.
17:12
Um, and maybe some other ways that you could go about looking at this
17:17
that I didn't spend the time doing, but let me explain what's happening here.
17:22
There is a difference between the crankshaft sensors and it's the
17:25
sensors only actually, I did some research on this.
17:28
The tone wheel that is sandwiched between the flex plate in the back
17:33
of the crank, it is not different, right?
17:35
If I go back to that Chevy cruise, the one for the part number for
17:40
the tone wheel is the same between the auto stop, start version and
17:44
the non auto stop, start version.
17:47
It is the sensor that is a different part.
17:49
And that's why back on that Chevy cruise, we were able to just pop
17:54
the original sensor back in and it worked.
17:57
We didn't have to change the tone ring.
17:59
Um, at the time, I didn't quite understand it, but looking
18:03
up the parts and repair link, they don't change anything about the
18:06
Now it's just a metal wheel with a magnetic strip on the outside,
18:10
but it can be used for both versions.
18:13
Again, in that Chevy cruise, in this Malibu, again, they only
18:16
have one version of this tone wheel and they only have one version
18:20
of the crankshaft sensor that you're supposed to buy for this one.
18:23
Um, but there is something different about the output of the crankshaft
18:28
sensors, the non auto stop versus this auto stop start that outputs
18:34
somewhat of a different signal as the engine's rotating.
18:38
So as far as I can find, um, and I looked into this as much as I
18:44
could and GM doesn't give a whole lot of specifics, but the main
18:48
difference between these sensors is that the stop start version can
18:53
output not only the, you know, position and the speed of the
18:57
crankshaft, but the direction of the crankshaft.
19:01
And there's some sites that list, you know, some details about
19:05
these types of sensors.
19:07
It may not be the exact one used in this GM, but that they have,
19:11
um, a series of hall effect elements within the tip of the
19:15
sensor and that way it can tell the direction that the
19:19
crankshaft rotated, particularly in an auto stop start event.
19:25
Because the engine comes to a stop and maybe it rotates back just
19:30
a hair as it comes, you know, it's coming to a complete stop.
19:34
And the engine computer wants to know the exact position of that
19:40
engine so that when you release your brake pedal, it can get
19:44
that thing started as soon as possible.
19:46
It wants to make it, or the goal of the system is to be
19:49
as seamless as possible to the driver.
19:51
So a lot of people don't like it, obviously, but they
19:54
tried their best to make it seamless and in order to know the
19:58
exact position of the crankshaft sensor, it's going to need to
20:01
know if it rolled back just a hair as it's coming to a stop so
20:05
that it can get the injectors and the coils firing as soon as
20:09
possible, as opposed to a normal start right after the vehicle
20:13
has been completely shut off, you might get a revolution or
20:16
two out of that engine before it figures out, okay, here's
20:20
the missing notch and okay, now we can start firing coils
20:23
and injectors at this point.
20:26
So you get a not an extended crank, but you get a longer crank
20:30
after a full shutdown versus one of these auto stop starts,
20:33
right. And so the sensor is the key piece of that in these
20:36
GMs does not appear to be the tone wheel.
20:39
The magnetic pieces of this tone wheel seem to be the same.
20:46
And they do note that this is one of those tone wheels that
20:49
you can't get near other metallic surfaces.
20:53
That it could ruin the tone wheel kind of like the ones on the
20:58
Mopar 3.6 liter camshafts, same thing, you can't set those on
21:03
a metal bench or set them near each other, they'll screw up the
21:06
tone wheel. They put the warning there on the parts listing
21:11
in repair link from GM. So they've obviously had some issues
21:15
with it and they make note like, hey, be careful with this
21:18
thing, careful where you set it or what you set it up
21:20
against. So it's a magnetic strip on here, the sensors
21:25
registering. But again, it appears to be the same in both
21:29
versions. Again, with Malbu, I only have one option. But when the
21:33
wrong sensor was put into that cruise, it was enough to allow
21:38
the engine to start and run. So again, the spacing the tone
21:42
wheel is the same and the sensors out putting something
21:45
enough for the engine computer to say, okay, hey, here's
21:48
the position of the crank, I'm going to fire the injector, I'm
21:52
going to fire the coil and the engine runs on this Malbu, you
21:56
could sit there and let it run all day. Yeah, it has a surge,
21:58
but it wasn't running poorly beyond that it was running just
22:02
fine. But what I believe is happening here is there's
22:06
something about the output of the crankshaft sensor that is
22:10
different between the auto stop star version, and the version
22:14
of sensor that is installed in both cases here, that the engine
22:19
computer does not fully recognize it as a successful start,
22:24
even though it's running the engine. And that's the weird
22:27
part. It's part I can't exactly explain what's happening in
22:30
the software. But it's, it will continue to run the engine.
22:34
Again, you put it into gear, and it will stall at that
22:38
point on this Malbu. But if you just let it sit there in
22:41
park, it will continue to run it. But I don't think the
22:44
engine computer is sending out over the bus like a successful
22:48
start. And I looked for some data pins and I could not find
22:51
anything that indicated it one way or another. I went into the
22:55
power mode settings of the BCM. And it just reflected the
22:59
state of the ignition switch and what it wanted the vehicle to
23:03
be at. There wasn't any indication of a load shedding
23:06
that I could find in the electrical management. Now I
23:10
bet might be missing something. And I didn't waste too much
23:13
time here and I'll explain why. But there's got to be something
23:18
that is broadcast from the engine control module to the rest of
23:21
the modules, power steering and BCM definitely appear to be
23:26
two of the important ones that puts it in a state like if the
23:30
engine wasn't running, right? The electric power steering not
23:34
operational, the alternator not charging correctly, the rear
23:38
defrost in the heated seats. Now those should work if your
23:41
key is just on. But what about in, you know, like some sort of
23:47
cranking state or something like that is a very strange state
23:51
that the vehicle is in. And again, not sending any codes
23:55
either. So this must be some default method that it sends
24:00
out to the network for it to be in this state. And it's
24:04
just weird that it gets here. But it'll continue to allow
24:08
the engine to run. Anyways, very strange. I don't have all the
24:12
explanations for it. But I know this is how the symptoms present
24:15
themselves exactly. So here's what I did. Instead of scoping
24:20
the crank pattern, which might be interesting, I'm sure you're
24:23
going to see a difference there. Honestly, it's more that's
24:26
more of an interesting and not critical for me to understand
24:30
because there's an easier way to determine this. Data Pids,
24:34
maybe I could find something if I dug through it and looked at
24:37
it really closely. Again, not super important because there's
24:40
a more practical way to do this. Here's how you do this. If you
24:43
have these symptoms, right, I'm going to run through it again.
24:46
Start or dragging after you hit the start button and you've
24:50
got to press the button again to get it to stop. The power
24:56
steering is inoperative. The charging voltage is fixed at
25:00
12. Your rear defrost and your heated seats don't work and
25:03
your idle surges up and down. And it stalls when you put
25:06
it into gear. You have all of that. You have no codes in the
25:09
system. Here's what you do. Shut the vehicle off, reach down to
25:14
the crankshaft sensor and unplug it. Go back in, start the vehicle
25:18
up. It will give you an extended crank. It will start. It
25:22
will set a code for the crankshaft sensor, but it will run
25:25
off of the camshafts, which a lot of vehicles nowadays can
25:29
do. They can completely run without a crankshaft
25:32
signal. Now you'll get an extended crank. Maybe it won't
25:35
be running that great. Maybe you can't go drive it around, but
25:38
it'll start and it'll run off the camshafts. There's enough
25:41
position information off of modern camshaft tone wheels so
25:45
that the engine computer can figure out where the engine is
25:48
and run the engine. Now again, you'll have a code, but
25:51
here's the thing. Here's how this is getting you to the
25:55
answer that this is what you're dealing with. All of that
25:57
other stuff, all of those other symptoms are now gone.
26:00
Okay, you got a code for the crankshaft sensor, your
26:03
check engine lights on, but your power steering works. Your
26:06
charging system is operating correctly. You can use the heated
26:10
seats. You can use the rear defrost. You can put the car
26:12
into gear. The idle thing, I don't know, I guess they didn't
26:15
pay attention to whether we're surging or not. You don't
26:18
have a crank sensor, so it's not going to be perfect, but it
26:21
eliminates all of that other stuff that you were dealing
26:23
with. And why? Because you've taken the bad input away
26:28
from the ECM. Now you've removed the input completely. So
26:31
it's going to have to go into a different default state, but
26:35
there's a difference between no crankshaft signal at all and a
26:39
pattern that must confuse it enough to not exactly know what
26:44
state that it's in. But if you do that, and you get rid of all
26:48
those symptoms, you know, you have to go after that
26:51
crankshaft sensor 100%. I don't care if you can see that it
26:55
was changed or not. The next time I get this grouping of
26:58
symptoms on one of these GM cars, I'm just gonna unplug the
27:01
sensor. Does the rest of that go away? Okay, you guys need to
27:04
change the sensor. Or in this case, we yanked it out, we
27:07
looked at it. Now, I did talk to him. He's like, yeah, we
27:09
ordered that from, it was, I don't know, aftermarket or
27:13
Riley's AutoZone, something like that. He's like, they didn't
27:15
have an option for, you know, an auto stop start. I was
27:18
like, well, maybe ask around a couple other places. And
27:22
from my research after the fact, he's correct, they only
27:25
list one. But I told him, maybe get a GM sensor or, you
27:30
know, AC Delco or whoever makes the OE sensor for this, you
27:34
might want to go that way. And I think that's what they did. And
27:36
that resolved the problem. And in this case, I don't know, that
27:41
sensor that was in there, did they just give them the wrong
27:43
one? Is there variants in aftermarket parts? I know there
27:47
is, right? We deal with failed or inaccurate aftermarket
27:52
electrical components all the time. So whether it was wrong
27:56
or just bad or for something else, I have no idea. Doesn't
28:01
matter in this case, because again, that it exhibited the same
28:07
symptoms as that cruise from five years ago. So final point
28:12
on this, I mean, again, you get a real practical way to get to
28:14
the solution fast on one of these. And this is the type of
28:17
problem that can really throw somebody for a loop if you're
28:20
not aware of this, because it's a very strange situation. So
28:24
you've got that. But the other thing that I'm always
28:27
preaching about on this show, and I encourage everybody to do
28:31
because it's now easier than ever to do this is to document
28:35
this stuff for yourself, right? Now, could I have remembered
28:39
that? Hey, I had this really weird Chevy cruise and it was
28:41
this. Oh, let's look at the crank sensor. Sure. But like to
28:44
have all of the details down to the specific things like
28:49
an idle surge documented five years later for me to listen
28:53
to, that's huge. That is so incredibly powerful. So again,
28:58
like always, I encourage you to record stuff like this, things
29:03
that you learn along the day on the job, the details, the
29:06
little stuff like there should be 2.5 volts on this circuit,
29:09
not 4.2 in this situation, or, you know, a pulsing voltage
29:14
comes from this module on this circuit, and that's normal
29:17
in this case, right? That sort of stuff. And I have the
29:21
episodes on utilizing AI where you can just blab into it, you
29:26
get it to output a really nice formatted version of all the
29:31
details that you want, and then put it in your storage
29:34
location of choice, you know, a Google Drive, an external
29:38
hard drive, whatever you want, write it down in a notebook if
29:41
you want to, it's just the tools now to record capture
29:46
what you're doing. It's so easy to do. And I don't know
29:51
why you wouldn't be doing it. So this is just an example of
29:54
that where I had dealt with a problem before the experience is
29:58
obviously key to that you're out there doing your learning, but
30:01
then capturing that so that you can refer back to it later.
30:05
This made this diagnosis like a snap, like I moved through
30:11
this one very, very quickly. But this is the type of
30:14
diagnosis that you can charge really good money for,
30:18
because this shop, I don't know how much money they spent, you
30:22
know, trying to resolve this problem that I think they
30:25
actually built it in by replacing the sensor. I'm guessing
30:29
they probably did it. The tech was, he was a little bit
30:35
flustered when he when I showed him the sensor. I think
30:39
they may have done it when they were attempting to fix the
30:42
original camshaft sensor issue because a non moving camshaft
30:46
just on the end is kind of a weird problem. I'm guessing he
30:51
didn't say that straight out, but I wasn't going to press him. It
30:54
doesn't matter to me who replaced it. That's the fix. But again,
30:58
to have all that information on hand, and I blew right through
31:03
that one and made a decent amount of money off it too. So that's
31:06
all I got for today. I want to say thank you to everybody
31:10
for listening. With that all the way, let's get out there,
31:13
start fixing the world one car at a time.
