Hey all!

I have a 2006 GP GT with the L32 supercharged motor with an intermittent issue that throws both P1125 (accelerator pedal sensor fault) and P2138 (Throttle/Pedal Pos Sensor/Switch D / E Voltage Correlation) and throws the car into limp mode. I've looked at most of the wiring pertaining to this circuit, just havent had the time to really get up under the dash and inspect everything. Underhood wiring looks good, no shorts there, throttle body opens and closes smoothly and freely. Has anybody had this issue before? I've done some digging around on forums and found that this can be a pretty challenging issue to solve if it isnt simply the accelerator pedal sensor going bad.

If you've had experience with this before, what did you do?

Actually, I have. I have NOT however pulled back the wiring loom on that particular section of harness to look at the wires. I'll do that in the morning when it's light out. Part of me is confused because the problem is intermittent, usually around 10 minutes or so after starting a drive. I can idle for as long as I want and the codes don't trip and I don't go into reduced power mode.
