APP Sensor Signal Inspection

NOTE:
  • This procedure checks the APP sensor in this fully closed position. In any other position, the APP sensor stores DTCs which are covered in other troubleshooting procedures.
  • Check for Temporary DTCs or 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.
  1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
  1. Turn the ignition switch to ON (II).
  1. Make sure the HDS communicates with the ECM/PCM. If it doesn't, go to the DLC circuit troubleshooting.
  1. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS.
