Throttle Position Sensor: Testing and Inspection

ON-VEHICLE INSPECTION

1. Inspect throttle position sensor.
- Disconnect the sensor connector.





- Insert a thickness gauge between the throttle stop screw and stop lever.








- Using an ohmmeter. measure the resistance between each terminal.
- Reconnect the sensor connector.

OFF-VEHICLE INSPECTION

1. Inspect throttle position sensor.
2. If necessary, adjust throttle position sensor.





- Loosen the 2 screws of the sensor.





- Insert a thickness gauge 0.83 mm (0.0325 in.) between the throttle stop screw and lever, and connect the ohmmeter to terminals IDL and E2.





- Gradually turn the sensor clockwise until the ohmmeter deflects, and secure the sensor with the 2 screws.








- Using a thickness gauge, recheck the continuity between terminals IDL and E2.
