APP Sensor Signal Inspection

NOTE:
This procedure checks the APP sensor in its fully closed position. In any other position, the PCM stores the APP sensor DTCs which are covered in other troubleshooting procedures.
Check for Pending or Confirmed DTCs with the HDS before doing this procedure. If any DTCs are indicated, troubleshoot them first, then do this procedure.
Press the accelerator pedal several times to check its operation. If it does not operate smoothly, check the pedal. If you find a problem, replace the accelerator pedal module.
