Throttle Position Sensor: Service and Repair

Fig. 20 Installing throttle position sensor:

Fig. 21 Adjusting throttle position sensor:

Replace
1. Remove throttle position attaching screws, then the throttle position sensor from throttle body.
2. Install new throttle position sensor on throttle body, then insert and temporarily tighten attaching bolts so that installation angle of sensor can be adjusted.
3. Adjust angle of throttle position as follows:
a. Insert a .024 inch thickness gauge between throttle stop screw and throttle lever. Move throttle position lever as necessary until continuity between terminals IDL and E2 is present, Fig. 20. At that position, torque sensor screw to 1.2 - 1.7 ft. lbs.
b. Ensure no continuity exists between IDL and E2 of throttle position sensor when a .031 inch thickness gauge is inserted between throttle stop screw and throttle lever, Fig. 21.
c. Ensure continuity exists between terminals IDL and E2 of throttle position sensor when .016 inch thick gauge is inserted between throttle stop screw and throttle lever.
d. If checks are not as specified, adjust angle of throttle position sensor until satisfactory results are obtained.
4. Connect connector to throttle position sensor.
