Accelerator Pedal Position Sensor: Testing and Inspection
APP Sensor Signal Inspection
NOTE:
- This procedure checks the APP sensor in its fully closed position. In any other position, the APP sensor stores DTCs which are covered in other troubleshooting procedures.
- Check for Pending DTCs 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 properly, check the pedal, the throttle cable, and the APP sensor individually. If you find a problem in one of them, replace the part(s) that caused the problem.
1. Connect the HDS to the data link connector (DLC) (A) located behind the driver's side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the ECM/PCM. If it doesn't, go to the DLC circuit troubleshooting Testing and Inspection.
4. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS.
- If it is below 2 %, the APP sensor is OK.
- If it is above 2 %, adjust the throttle cable Adjustments, then go to step 5.
5. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS.
