02 TB i6
Already replaced ign switch, clean throttle, cpas. And the fuse box.
Truck was given to me from a friend who owned it for 10 years and replaced the tranny 3 times. Kept great maintenance and minimal issues.
Over a few years I keep having these reoccurring issues and don't know if they're related. I've had a shop fix it each time which said the wiring was damaged behind the fuse box.
The issues started happening only at 55-60 when the ABS light would come on, followed by the rps jumping from 1500-2000 ish. It would stop at first but then it would stall after the first few times of the rpm and ABS issue. The truck would stall, it starts back up without a code and then a few miles later or less it stalls again.
Now its doing it again. I got a code 2 days ago for p0013. Ive replaced this part twice for the code coming up before.
This time i took a look at the wiring myself and found at some point, someone ran a direct new wire for the CPAS straight to the ECM. I found the original brown wire disconnected, also found that the new CPAS wire and the ground had both been poorly wrapprd with open wires (both CPAS wires) that seemed to be touching when it was unwrapped. Not good so i cleaned them up and checked continuity for the new CPAS wire and it checked out fine. No code for 2 days for that sensor or wiring.
Then today, no code but the truck stalled 3 times on the way to work. Wtf please direct me where to start? I don't see any bad wiring in the harness behind the fuse panel.
My to do list to check so far, please impute advice, is to check the IAT sensor and if that checks out fine possibly pull the tranny pan and test the TCC. Found a nice video on how to diagnose that sensor.
Im just bad with knowing how to use a multimeter well and where to find needed circuits. What else could be causing my issues? How does this issue keep happening every 3 to 4 months...
FYI, the original owner had an aftermarket intake installed and the IAT sensor could possibly be jacked up. this would be the easiest fix but doesn't really explain why the ABS light would come on.
