well if i'm understanding this 1374 thing(pdf)so far your car is
currently running on the 24x reference signal(crank sensor) and cam
signal.1374 means the ICM is ignored(3X) as an input to PCM.so then why
did the car run better with a new one?hmmmm.and even without ICM input
car should start and run on 24x and cam signal.you replaced the crank
sensor.you joked about the cam sensor.hmmmm.

Nope. Replaced the wire that was bad, the P1374 code still throws.
We give up, it's going to the shop tomorrow.

Still not solved yet. Shop found 3 bad wires (which they fixed) which
also fried the computer. Replaced computer, took to dealer for
reprogramming, car still acts up, bucking, stalling, cutting out, etc.
Have not put it on the code scanner just yet to see if it's the exact
same code or not yet. Man this problem is just a total bear...any
experts out there want to take another crack at this one? Or do we
just flat out have an unfixable problem here?

Every problem has a solution.
Seems odd that you found bad wires, maybe there is more. Was one of the bad
wires going to the crank sensor? Were the bad wires repaired properly? Why
were there bad wires? Maybe there is an underlying issue no one is
addressing.

Not sure exactly which bad wires were fixed, the shop fixed them, they
just said 3 bad wires, behind the alternator if I'm not mistaken. As
far as I know the 3 bad wires were repaired properly. I'm not 100%
sure why or how the wires went bad. Something about the 3 wires were
rubbing and shorted out which fried the computer. Also, got a chance
to scan the codes again after I got it home. P1374 code came up
twice, and P0108 came up once. P0108 indicates MAP sensor, but that's
already been replaced.

Was the MAP sensor the case of the P0108? |

We replaced the MAP sensor because the p0108 code came up before. Now
it's coming up with 2 P1374 codes and 1 P0108 code. It's currently
back at the shop that "diagnosed" it. They are going to be eating the
labor until they find out exactly what the problem is, I'm beginning
to wonder if it really was the computer after all at this point.

So replacing the MAP didn't fix the P0108?
The first step in diagnosing a P0108 asks "Is the idle rough/unstable etc?"
"If so, repair idle first before trying to diagnose P0108."

Actually in the troubleshooting for the P0108 code, it states that if
you have a P1374 code to fix that first and see if it goes away. We
replaced the MAP sensor anyway because it was relatively inexpensive,
but at the end of the day it really didn't solve anything. The dealer
(that reprogrammed the computer) is of the opinion it could be the
harmonic balancer (aka vibration dampener) because "it's a common
problem" they see in their shop. We took the thing off to replace the
crank sensor on this car, and it seemed fine to me, so I doubt that's
it, but of course I could be wrong. Unfortunately a new one is $70!

What? Who told you that. I'm looking at the factory diagnositc chart and it
says nothing of the sort. You always fix the lower numbers first. ;)

Whoops, I was wrong, that info relates to the P0101 code, which this
car also was throwing at one point (not anymore) - "Using scan tool,
check for stored DTCs. If DTC P1635 or P1374 is also set, diagnose
that DTC first." So many codes, it gets confusing ;)
I think I also forgot to mention, that coming home from the dealer the
car was acting up like crazy and the check engine light came on almost
right away. Cleared the codes, drove it from my house back to the
shop that 'diagnosed' it, and it only acted up a little bit and the
check engine light didn't come back on, even though the shop is
further away than the dealer was. I have no doubt in my mind that the
code came back though, I should have brought the scantool with me and
checked it once we hit the shop.

Just wanted to update everyone on the latest in this ongoing saga.
The shop that was supposed to be re-diagnosing decided to replace the
harmonic balancer and now is presenting us with a repair bill. Bear
in mind that NOBODY but NOBODY gave them authorization to do so, plus
the fact that we already bought a new balancer and can put it on just
fine ourselves in ~20 mins or so, plus the fact that the CHECK ENGINE
LIGHT IS STILL ON and the same codes are still present, P1374 (x 2),
however they're claiming "the car runs fine." Well that may be the
case, but it still starts hard and those codes are still there. This
shop was paid for diagnosing a specific problem (the cause of the
P1374 code) and thusfar have failed to do so. At this point I want
them to undo the work they did that they were not authorized to do,
we'll put the harmonic balancer on ourselves, and I want my money back
in full (because their "diagnosis" has bore no fruit) and the car's
going to go to the dealer, obviously whatever is wrong is obviously
beyond mere mortals if it's stumped my friend, the mechanic with 27
years experience, myself, with enough common sense that we should have
been able to figure this out, plus some suggestions from you guys,
plus a shop that's been in business for at least 15 years. You stump
those 3-4 entities, it's time to bite the bullet and take it to the
real pros.

It codes out at as a "3x Reference Circuit" error. Not sure what they |
are refering to here though
