APP Sensor Signal Inspection
2006 Honda Pilot LX, 3.5 YF1, J35A9SECTION 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 procedure.
- 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 movement. If it does not move smoothly, 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.
- Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard
- Turn the ignition switch ON (II).
- 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 (see RESONATOR REMOVAL/INSTALLATION ), then go to step 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%, update the PCM if it does not have the latest software (see PCM UPDATING AND SUBSTITUTION FOR TESTING ), or substitute a known-good PCM (see HOW TO SUBSTITUTE THE 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 below 2%, the APP sensor is OK.
- If it is above 2%, replace the APP sensor (see APP SENSOR REPLACEMENT ), then go to step 1.
