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 - 1.1 V
Accelerator pedal depress: 2.6 - 4.5 V

d. Check if the voltage (ACCEL POS #2) of the CURRENT DATA indicates the standard value.

Accelerator pedal released: 1.2 - 2.0 V
Accelerator pedal depress: 3.4 - 5.3 V

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