ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [MZR-CD (RF Turbo)]

id0140f1803200

  Note

  • Perform the following inspection only when directed.

## Voltage Inspection

1. Connect the WDS or equivalent to the DLC-2.

2. Turn the engine switch to ON.

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 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. (See ACCELERATOR PEDAL COMPONENT REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

Specification

Condition | APP1 PID (%) | APP1 PID (V) | APP2 PID (%) | APP2 PID (V)
--- | --- | --- | --- | ---
Accelerator pedal is released | 0 | Approx. 1.04 | 0 | Approx. 1.58
Accelerator pedal is depressed | 100 | Approx. 3.35 | 100 | Approx. 3.89

## Circuit Open/Short Inspection

1. Disconnect the negative battery cable.

2. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

3. Disconnect the APP sensor connector.
