Sub-Throttle Position Sensor

1. Remove screws and sub-throttle actuator. See Fig 1. Disconnect electrical connector from sub-throttle position sensor.
2. Ensure no clearance exists between throttle stop screw and throttle valve gear with sub-throttle valve fully closed. Perform STEP 1. See Fig 2-12.
3. Place sub-throttle valve in fully closed position. Loosen sub-throttle position sensor mounting screws. Connect ohmmeter between terminals IDL and E2. Perform STEP 2. See Fig 2-12.
4. To set initial clearance, insert .018" (.45 mm) feeler gauge between throttle stop screw and throttle valve gear. Perform STEP 3. See Fig 2-12.
5. With ohmmeter showing no continuity, rotate sub-throttle position sensor clockwise until continuity exists. Tighten sub-throttle position sensor mounting screws.
6. Remove feeler gauge. Insert a .016" (.41 mm) feeler gauge. Ensure continuity still exists. Remove feeler gauge. Insert a .019" (.48 mm) feeler gauge. Ensure continuity no longer exists. Reinstall sub-throttle actuator. Install electrical connector on sub-throttle position sensor.
