What else did you do? Sounds like you have some wiring goofs - shorts, opens etc.

have you started tracking down your wiring?

What DTCs does your car have recorded in the transmission control module as a TCM error request is in the above list?

From the TCU, Don't think I've cleared these settings, I've been clearing the engine ones and they keep coming back.


18265 - Load Signal: Error Message from ECU
P1857 - 35-00 - -
17125 - Torque Converter Clutch Circuit Performance or Stuck Off.
P0741 - 35-00 - -
17147 - Shift Solenoid 3 (N90): Circuit Failure
P0763 - 35-10 - - - Intermittent
17142 - Shift Solenoid 2 (N89): Circuit Failure
P0758 - 35-10 - - - Intermittent
18258 - Powertrain Data Bus: Missing Message from ECU
P1850 - 35-10 - - - Intermittent

I pulled the engine and tranny out a couple times when replacing the turbos, so it's definitely possible. Also vehicle was in an accident and I fixed most items and it ran fine for a while, so wiring might be possible.

The central convenience module was fried from water damage and I just replaced that, but still same issues. What's odd is I thought the MAP sensor was reading 0 and with the CCM being replaced it now reads something.

Peter Badore

You should clear all the intermittent DTCs and see if 17125 keeps coming back. If it does you have a torque converter problem. Search for that failure and I think you will see similar postings with DTC 17125. The check engine light will be on from the TCM DTC 17125.

Not really worried about the tranny issues. Want to get the car out of limp mode so I can diag all issues.

cam sensor 1 is short to plus
cam sensor 2 is short to ground
G31 boost sensor is low signal

all 3 share same 5V and ground wiring. I figured if issue then they all would have same errors.

Are you not in transmission limp mode with all the PRNDL lamps illuminated?

ddillenger

Did you pull the trans to install the turbos? Any chance you pinched a wire between the trans bellhousing and block?

justinm0424

I pulled the engine with tranny attached. Could of pinched a wire another place though but don't remember it.

Not certain if the PRNDL lamps illuminated.... is this in the speedo cluster or on the actual shifter??? One issue is I broke the panel that lights the shifter area, but it still works I believe.
