Throttle Position (TP) Sensor: Adjustment
- Disconnect TP sensor connector. Connect ohmmeter between TP sensor connector terminals "E" and IDL. See Fig 1. Loosen TP sensor attaching screws.
- Insert a .010" (.25 mm) feeler gauge between throttle lever and throttle stop screw. Rotate TP sensor clockwise about 30 degrees, then rotate counterclockwise until ohmmeter indicates continuity.
- Remove feeler gauge. Insert a .016" (.40 mm) feeler gauge between throttle lever and throttle stop screw. If ohmmeter indicates no continuity, go to next step. If ohmmeter indicates continuity, repeat adjustment procedure.
- Tighten TP sensor attaching screws. Open throttle valve fully and verify resistance between terminals "E" and Vt is about 5000 ohms.

- Disconnect TP sensor connector. Connect ohmmeter between terminals IDL and TL/E of TP sensor connector. See Fig 1. Insert a .016" (.41 mm) feeler gauge between throttle lever and throttle stop screw.
- Loosen TP sensor screws. Rotate TP sensor clockwise about 30 degrees, then rotate counterclockwise until ohmmeter indicates continuity.
- Remove feeler gauge. Insert a .027" (.69 mm) feeler gauge between throttle lever and throttle stop screw. If ohmmeter indicates no continuity, go to next step. If ohmmeter indicates continuity, repeat adjustment procedure.
- Tighten TP sensor attaching screws. Open throttle valve fully a few times. Recheck TP sensor adjustment.
