2007 Honda Element LX, 2.4 YH1, AutomaticFACTORY OEM SERVICE PROCEDURE

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 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 operation. If it does not operate properly, 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 behind the driver's side of the dashboard.

  2. Turn the ignition switch ON (II).
  3. Make sure the HDS communicates with the vehicle and the ECM/PCM. If it doesn't, go to DTC TROUBLESHOOTING .
  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%, adjust the throttle cable (see THROTTLE CABLE ADJUSTMENT ), 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%, update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step  6.
  6. 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.
