Accelerator Pedal Position Sensor: Testing and Inspection
ACCELERATOR PEDAL POSITION SENSOR CHECK1. 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 Kiloohms
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].
Normal condition:
When accelerator pedal is gently depressed Changes comparatively smoothly in proportion to the accelerator pedal depression amount.
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.
