Off-Vehicle Inspection
THROTTLE BODY INSPECTION1. INSPECT THROTTLE VALVE
- Apply vacuum to the throttle opener.
- Check that there is no clearance between the throttle stop screw and throttle lever when the throttle valve is fully closed.
2. INSPECT THROTTLE POSITION SENSOR
- Apply vacuum to the throttle opener.
- Insert a feeler gauge between the throttle stop screw and stop lever.
- Using an ohmmeter, measure the resistance between each terminal.
3. IF NECESSARY, ADJUST THROTTLE POSITION SENSOR
- Loosen the 2 set screws of the sensor.
- Apply vacuum to the throttle opener.
- Insert a 0.54 mm (0.021 in.) feeler gauge, between the throttle stop screw and stop lever.
- Connect the test probe of an ohmmeter to the terminals IDL and E2 of the sensor.
- Gradually turn the sensor clockwise until the ohmmeter deflects, and secure it with the 2 set screws.
- Recheck the continuity between terminals IDL and E2.
