ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION

BHE014041600W01

  Note

  • Before performing the following inspection, make sure to follow the troubleshooting flowchart. (See Troubleshooting Procedure.)

## Voltage Inspection

1. Turn the ignition switch to the ON position.

2. Verify that the voltage at PCM terminals 5F (WDS PID: APP1) and 5C (WDS PID: APP2) increases while gradually increasing the accelerator pedal opening angle according to the accelerator pedal opening angle.

  • If it can be verified, go to the next step.
  • If it cannot be verified even though the related wiring harnesses have no malfunction, replace the accelerator pedal.

3. Verify that the voltage at PCM terminals 5F (WDS PID: APP1) and 5C (WDS PID: APP2) is as indicated in the table.

  • If it cannot be verified, replace the accelerator pedal. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION.)

  APP sensor output voltage

  Measurement condition | PCM terminal (WDS PID)
  --- | ---
  5F (APP1) | 5C (APP2)
  When the accelerator pedal is depressed. | 3.78-3.93 V | 3.23-3.38 V
  When the accelerator pedal is released. | 1.555-1.655 V | 1.005-1.105 V

## Circuit Open/Short Inspection

1. Disconnect the PCM connectors.

2. Disconnect the APP sensor connector.

3. Inspect the following wiring harnesses for open or short circuit. (Continuity inspection)

### Open circuit

  • If there is no continuity in the following wiring harnesses, there is an open circuit. Repair or replace the wiring harness.
  – APP sensor terminal A and PCM terminal 4X
  – APP sensor terminal B and PCM terminal 5AB
  – APP sensor terminal C and PCM terminal 5C
  – APP sensor terminal D and PCM terminal 4Y
  – APP sensor terminal E and PCM terminal 5AE
  – APP sensor terminal F and PCM terminal 5F

### Short circuit

  • If there is continuity in the following wiring harnesses, there is a short circuit. Repair or replace the wiring harness.
  – APP sensor terminal D and body ground
  – APP sensor terminal D and power supply
  – APP sensor terminal A and body ground
  – APP sensor terminal A and power supply
  – APP sensor terminal F and body ground
  – APP sensor terminal F and power supply
  – APP sensor terminal C and body ground
  – APP sensor terminal C and power supply
