1. Remove the electrical connector (1) from the idle air control (IAC) valve (4).
2. Remove the IAC valve attaching screws (2) from the IAC valve (1).



3. Remove the IAC valve from the throttle body.
4. Remove the IAC valve O-ring.

Notice: The IAC valve may be damaged if installed with the cone (pintle) extended more than 28 mm (1-1/8 in). Measure the distance that the valve is extended before installing a new valve. The distance from the idle air control valve motor housing to the end of the idle air control valve pintle should be less than 28 mm (1-1/8 in). Manually compress the pintle until the extension is less than 28 mm (1-1/8 in).

1. Install the new O-ring on the IAC valve.
2. Install the IAC valve into the throttle body.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the idle air control valve attaching screws (2).

Tighten
Tighten the idle air control valve attaching screws to 3 N·m (27 lb in).

4. Install the electrical connector (1) into the idle air control valve.
5. Perform the IAC valve learn procedure.
