Accelerator Pedal Position (APP) Sensor Inspection

If faulty condition is found, replace accelerator pedal assembly (incorporating APP sensor assembly). See ACCELERATOR PEDAL ASSEMBLY (INCORPORATING APP SENSOR) REMOVAL AND INSTALLATION .

1. Connect three new 1.5 V batteries (1) in series, and check that total voltage is 4.5 - 5.0 V.
2. Connect voltmeter (2) and batteries to APP sensor as shown in figure.
