Accelerator Pedal Position Sensor: Testing and Inspection

INSPECT ACCELERATOR PEDAL POSITION SENSOR

a. Connect the hand-held tester to the DLC3.
b. Turn the ignition switch ON.
c. Check if the voltage (ACCEL POS) of the CURRENT DATA indicates the standard value.
Accelerator pedal released: 0.5 to 1.1 V
Accelerator pedal depressed: 2.6 to 4.5 V

d. Check if the voltage (ACCEL POS #2) of the CURRENT DATA indicates the standard value.
Accelerator pedal released: 1.2 to 2.0 V
Accelerator pedal depressed: 3.4 to 5.3 V

If the hand-held tester is not available, measure the voltage between the terminals (VPA - EPA, VPA2 - EPA2) of the ECM connector.

Idle speed: 650 to 750 rpm
