Accelerator Pedal Position Sensor: Testing and Inspection

ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [AJ]

NOTE: Perform the following inspection only when directed.




1. Connect the WDS or equivalent to the DLC-2.
2. Turn the ignition switch to ON position.
3. Select APP1 or APP2 PID (percentage) on the WDS or equivalent.
4. Verify that the APP1 or APP2 PID (percentage) changes smoothly while accelerator pedal is gradually depressed.
- If as verified, go to next step.
- If not as verified, perform the "Circuit Open/ Short Inspection".

5. Verify that the APP1 or APP2 PID (percentage) is as indicated in the table according to the condition of the accelerator pedal.




- If not verified, perform the "Circuit Open/Short Inspection".
- If there is no open or short circuit, replace the APP sensor.

Circuit Open/Short Inspection

1. Disconnect the PCM connector.




2. Inspect the following harness for open or short circuit. (Continuity check)
