DIAGNOSTIC TROUBLE CODES (DTC) LIST

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.

  1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard
  2. Turn the ignition switch ON (II).
  3. 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»(ref-243301-S20222944452006082300000) ), then go to step 4 .
  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»(ref-243311-S19790429062006082300000) ), or substitute a known-good PCM (see «HOW TO SUBSTITUTE THE PCM»(ref-243311-S24543735662006082300000) ), 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. If it is below 2%, the APP sensor is OK. If it is above 2%, replace the APP sensor (see «APP SENSOR REPLACEMENT»(ref-243329-S15068172982006082300000) ), then go to step 1 .

  1. Remove the bolts and the throttle cable cover (A).
  2. Remove the throttle cable (see «THROTTLE CABLE REMOVAL/INSTALLATION»(ref-243301-S24896655932006082300000) ).
  3. Disconnect the APP sensor 6P connector (A).
  4. Remove the bolts (B) and APP sensor (C).
  5. Install the parts in the reverse order of removal.
