APP Sensor Signal Inspection

Note. This procedure is to inspect the abnormalities of the APP sensor full closed position. Other failures than full closed position will store a DTC, therefore the steps to inspect them are not included in this procedure. 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, the throttle cable, and the APP sensor individually. If you find a problem in one of them, replace the parts that caused the problem.

Scheme 177

Scheme 177: APP Sensor Signal Inspection
  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 and 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 «THROTTLE CABLE ADJUSTMENT»(ref-219376-S32747651472006021400000) ), then go to step 4.
  4. Make sure the accelerator pedal is not pressed and 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 ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see «ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-219370-S15199960282006021400000) ), then go to step 5.
  5. Make sure the accelerator pedal is not pressed and 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-219372-S23656013552006021400000) ), then go to step 1 .
