Accelerator Pedal Position Sensor: Testing and Inspection

ACCELERATOR PEDAL POSITION SENSOR CHECK (Vehicles with TCL)
1. Disconnect the accelerator pedal position sensor connector.
2. Measure the resistance between the accelerator pedal position sensor side connector terminal 1 and terminal 4.

Standard value: 3.5 - 6.5 kOhm

3. Measure the resistance between the accelerator pedal position sensor side connector terminal 1 and terminal 2.

Normal Condition:
Throttle valve slowly open until fully open from the idle position
Changes smoothly in proportion to the opening angle of the throttle valve

4. If the resistance is outside the standard value, or if it doesn't change smoothly, replace the accelerator pedal position sensor.

NOTE: For the accelerator pedal position sensor adjustment procedure, refer to "Adjustments".




ACCELERATOR PEDAL POSITION SENSOR (APS) CHECK
1. Disconnect the APS connector.
2. Measure the resistance between terminals 1 and 4 of the APS connector.

Standard value: 3.5 - 6.5 kOhm

3. When the accelerator pedal is gradually depressed, check that the resistance between terminals 1 and 2 of the APS connector changes smoothly in proportion to the pedal opening amount.
4. If the resistance is outside the standard value, or if the resistance does not change smoothly, replace the APS. Adjust the APS after it has been replaced. (Refer to On-vehicle Service.)
