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 M-MDS to the DLC-2.
2. Turn the ignition switch to ON position.
3. Select APP1 or APP2 PID (percentage) on the M-MDS.
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".

Specification:

5. Verify that the APP1 or APP2 PID (percentage) is as indicated in the table below 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)
