Throttle Body
- Place throttle body on holding fixture. Before installing IAC assembly, measure distance that valve extends from motor housing.
- Measuring from gasket mounting surface of housing to end of pintle, distance should not exceed 1 1/8" (28 mm). If not to specification, push pintle inward (ISC valve with collar on electrical connector) or compress pintle retaining spring toward IAC body while turning pintle inward with a clockwise motion (IAC valve without collar on connector.
- On IAC valves without collar, return spring to original position with straight portion of spring end aligned with flat surface under pintle head.
- Install IAC assembly with new gasket. Tighten securely. Install TPS actuator lever by aligning flats on end of shaft. DO NOT install TPS until throttle body is completely assembled.
