Thickness Gauge Inserted Behind Stop Screw:

3. Insert a 0.5 mm (0.020 in) thickness gauge between the throttle stop screw and the stop lever.
4. Loosen the screws and rotate the sensor about 30°, then rotate the sensor back until the tool indicates continuity. Tighten the mounting screws.
5. Insert a 0.7 mm (0.027 in) thickness gauge between the throttle stop screw and stop lever and check that the tool does not indicate continuity. If it does, repeat steps 3 through 5.
6. Open the throttle plates a few times and recheck the adjustment of the throttle sensor.
