APP Sensor Signal Inspection
NOTE:
- This procedure is to inspect the abnormalities of the APP sensor full closed position.
- Check for Temporary DTCs or DTCs with the HDS before this procedure. If there are any DTCs indicated, troubleshoot them first, then do this procedure.
- Press the accelerator pedal several times, and check the operation. If it does not operate properly, check the accelerator pedal. If you find a problem, replace the accelerator pedal module (see ACCELERATOR PEDAL MODULE REMOVAL/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).
- 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 and 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, or substitute a known-good PCM (see SUBSTITUTING THE PCM ), then go to the step 4.
- Make sure the accelerator pedal is not pressed and 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/INSTALLATION ), then go to step 1.
