Throttle Position Sensor: Adjustments

1. Disconnect the electrical connector from the throttle position sensor.

Throttle Position (TP) Sensor:

2. Connect the leads of Rotunda 73 Digital Multimeter or equivalent to the IDL and E terminals on the throttle position sensor.

Throttle Position (TP) Sensor:

3. Loosen the throttle position sensor mounting screws.
4. Insert a 0.250 mm (0.010 inch) feeler gauge between the throttle stop screw and the stop lever.
5. Rotate the throttle position sensor clockwise approximately 30 degrees, then rotate counterclockwise until continuity exists.
6. Replace the 0.250 mm (0.010 inch) feeler gauge with a 0.40 mm (0.0160 inch) feeler gauge and insert it between the throttle stop screw and the stop lever.
7. Verify continuity no longer exists.

NOTE: If there is still continuity, repeat steps 4 through 7.

8. Tighten the throttle position sensor mounting screws while making sure not to move the throttle position sensor from its position.

Throttle Position (TP) Sensor:

9. Open the throttle plate to wide open throttle position several times and verify that the resistance between E and Vt terminals on the throttle position sensor is approximately 5K ohms at wide open throttle.
