ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [L8, LF, L3]

id0140a5803200

  Note

  • Perform the following inspection only when directed.

## Voltage Inspection

1. Turn the ignition key to ON position (Engine OFF).

2. Verify that the PCM terminal 1AO and 1AP change smoothly while throttle valve is gradually opened.

  • If as verified, go to next step.
  • If not as verified, perform the "Circuit Open/Short Inspection".

  - If there is no open or short circuit, replace the throttle body.

3. Verify that the PCM terminal 1AO and 1AP voltages are as shown in the following table.

  • If voltage is not as following table, perform the "Circuit Open/Short Inspection".

  - If there is no open or short circuit, replace accelerator pedal. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [L8, LF, L3].)

APP sensor output voltage

Condition | PCM terminal 1AO (APP sensor No.1) | PCM terminal 1AP (APP sensor No.2)
--- | --- | ---
Accelerator pedal released | 1.55-1.62 V | 1.01-1.07 V
Accelerator pedal depressed | 3.49-4.09 V | 2.94-3.54 V

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L8, LF, L3].)

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

### Open circuit

  • If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
  - APP sensor terminal A and PCM terminal 1AJ
  - APP sensor terminal B and PCM terminal 1AV
  - APP sensor terminal C and PCM terminal 1AP
  - APP sensor terminal D and PCM terminal 1AL
  - APP sensor terminal E and PCM terminal 1AS
  - APP sensor terminal F and PCM terminal 1AO

### Short circuit

  • If there is continuity, there is a short circuit. Repair or replace the wiring harness.
  - APP sensor terminal A and power supply
  - APP sensor terminal A and body GND
  - APP sensor terminal B and power supply
  - APP sensor terminal C and power supply
  - APP sensor terminal C and body GND
  - APP sensor terminal D and power supply
  - APP sensor terminal D and body GND
  - APP sensor terminal E and power supply
  - APP sensor terminal F and power supply
  - APP sensor terminal F and body GND
