Honda Civic Service Manual: APP Sensor Signal Inspection (K24Z7)

Inspection

1. HDS DLC - Connection


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 to ON (II).


3.

Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.


2. App Sensor Signal - Inspection


NOTE:

This procedure checks the APP sensor in its fully closed position (pedal not pressed). In any other position, the APP sensor stores DTCs which are covered in other troubleshooting procedures.

Check for Pending or Confirmed 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 smoothly, check the pedal. If you find a problem, replace the accelerator pedal module.

Make sure the HDS communicates with the ECM. If it doesn't, go to the DLC circuit troubleshooting.


4.

Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS.

With the accelerator pedal not pressed, 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, then recheck.
