Accelerator Pedal Position Sensor: Testing and Inspection

ACCELERATOR PEDAL POSITION SENSOR CHECK




1. Disconnect the accelerator pedal position sensor connector.




2. Measure the resistance between accelerator pedal position sensor connector terminal No.1 [accelerator pedal position sensor (main) earth] and terminal No.2 [accelerator pedal position sensor (main) power supply], and between terminal No.7 [accelerator pedal position sensor (sub) earth] and terminal No.8 [accelerator pedal position sensor (sub) power supply].

Standard value: 3.5 - 6.5 kOhms

3. Measure the resistance between accelerator pedal position sensor connector terminal No.2 [accelerator pedal position sensor (main) power supply] and terminal No.3 [accelerator pedal position sensor (main) output]; and between terminal No.8 [accelerator pedal position sensor (sub) power supply] and terminal No.6 [accelerator pedal position sensor (sub) output].
4. If the measured values are outside the standard value range, or if the resistance does not change smoothly, replace the accelerator pedal position sensor.

NOTE: After replacement, adjust the accelerator pedal position sensor.
