1. Turn OFF the ignition.



2. Disconnect the electrical connector from the idle air control (IAC) valve.



3. Remove the 2 screws that retain the IAC valve.



4. Remove the idle air control valve.



5. Remove the O-ring from the idle air control valve .

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 a new O-ring to the IAC valve.



2. Install the IAC valve in the intake manifold.




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 2 screws that retain the IAC valve.

Tighten
Tighten the screws to 3.0 N·m (27 lb in).




4. Connect the electrical connector to the idle air control valve .
5. Turn the ignition ON for 10 seconds, then OFF for 5 seconds in order to reset the IAC valve.
6. Start the engine and allow the engine to reach a normal operating temperature.
