Throttle Position Sensor: Testing and Inspection

SUB-THROTTLE POSITION SENSOR INSPECTION

1. Inspect sub-throttle position sensor.
- Set the sub-throttle valve to fully closed position.





- Insert a 0.41 mm (0.016 in.) or 0.48 mm (0.019 in.) feeler gauge between the throttle stop screw and throttle valve gear.








- Using an ohmmeter, measure the resistance between terminals.
2. If necessary, adjust sub-throttle position sensor.





- Loosen the 2 set screws of the sensor.
- Set the sub-throttle valve to fully closed position.





- Insert a 0.45 mm (0.018 in.) feeler gauge, between the throttle stop screw and throttle valve gear.





- Connect the tester probe of an ohmmeter to the terminals IDL and E2 of the sensor.
- Gradually turn the sensor clockwise until the ohmmeter deflects, and secure it with the 2 set screws.








- Recheck the continuity between terminals IDL and E2.
