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

id0140f1803200

Note

• Perform the following inspection only when directed.

Voltage Inspection

1. Connect the M-MDS to the DLC‐2.

am3zzw00004086

2. Turn the engine switch to ON.

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”.

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 REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
