Mazda CX-5 Service & Repair Manual: Accelerator Pedal Position (App) Sensor Inspection

Mazda CX-5 Service & Repair Manual / Engine / Control / Accelerator Pedal Position (App) Sensor Inspection

Voltage Inspection

NOTE:

Because the APP sensor is integrated in the accelerator pedal, replacing the APP sensor includes replacement of the accelerator pedal.

1. Connect the M-MDS to the DLC?2.

2. Switch the ignition ON (engine off or on).

3. Verify that the APP sensor output voltage (PID: APP1, APP2) increases according to the increase in the accelerator opening angle when the accelerator opening angle is gradually increased..

If verified, go to the next step.
If not as verified, replace the accelerator pedal..

4. Verify that the APP sensor output voltage (PID: APP1, APP2) is within the specification when the accelerator pedal is depressed and not depressed..

If not as specified, replace the accelerator pedal..
