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 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 (see ACCELERATOR PEDAL MODULE REMOVAL AND INSTALLATION )
- Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
- Make sure the HDS communicates with the PCM If it doesn't, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING )
- Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS
- If it is 0 %, the APP sensor is OK
- If it is not 0 %, update the PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ), then go to step 5
- Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS
- If it is 0 %, the APP sensor is OK
- If it is not 0 %, replace the accelerator pedal module (see ACCELERATOR PEDAL MODULE REMOVAL AND INSTALLATION ), then go to step 1
