Accelerator Pedal Position (APP) Sensor Inspection

APP (Accelerator Pedal Position) Sensor Inspection

1. Remove Accelerator Pedal assembly.
2. Check APP sensor output voltage as follows.
If faulty condition is found, replace accelerator pedal assembly (incorporated with APP sensor).
a. Connect 3 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.
