Metal Links
I have had the same issues but with additional codes of P2120 and P2125. I have replaced both pedal and TB with no help. I have searched the interweb for wiring diagrams and such with no luck. I have checked voltage at the pedal and have voltage at both pins that should have voltage but when the pedal is attached they read some difference. i have tried to find ground locations and also thought of a body control unit but can't find any info. So did you solve your issues?
Thanks Rick
