troubleshoot P2120's and P2125's???
anyone ever had to troubleshoot these 2 dtc's?
my car is throwing them like crazy, can't clear them, and the car is stuck in limp mode.
P2120 Accelerator Pedal Position (APP) Sensor 1 Circuit ECM, PCM
P2125 Accelerator Pedal Position (APP) Sensor 2 Circuit ECM, PCM

The Throttle Actuator (TAC) module that actually controls the throttle might be your culprit. The PCM is apparently having issues with it.

problem was due to a broken wire inside one of the harnesses.....
