Accelerator Pedal Position (APP) Sensor Inspection

Accelerator Pedal Position (APP) Sensor Inspection

1. Remove accelerator pedal assembly (incorporating APP sensor assembly).
2. Check APP sensor output voltage as follows.
If faulty condition is found, replace accelerator pedal assembly (incorporating APP sensor assembly).
a. Connect three new 1.5 V batteries (1) in series, and check that total voltage is 4.5 - 5.0 V.
b. Connect voltmeter (2) and batteries to APP sensor as shown in figure.










c. Check that voltage varies depending on accelerator opening angle as the following graph.
