Idle Speed/Throttle Actuator - Electronic: Service and Repair

REMOVAL
1. Air cleaner assembly.
2. IAC valve assembly (75) and gasket (76).

NOTICE:
- On IAC valves that have been in service: Do Not push or pull on the IAC valve pintle. The force required to move the pintle may damage the threads on the worm drive.
Also, Do Not soak IAC valve in any liquid cleaner or solvent, as damage may result.

CLEAN AND INSPECTION
- Both original and replacement IAC valves have a special factory applied thread-locking compound applied to the screw threads. If the valve removed from the throttle body is being reinstalled, Do Not attempt to remove any of the thread locking compound that may be remaining on the threads.
- Clean IAC valve gasket sealing surface, pintle valve seat and air passage.
- Use carburetor cleaner to remove carbon deposits. Do Not use a cleaner that contains methyl ethyl ketone. It is an extremely strong solvent, and not necessary for this type of deposit.
- Shiny spots on the pintle or seat are normal, and do not indicate misalignment or a bent pintle shaft.
- If air passage has heavy deposits, remove throttle body for complete cleaning.

IMPORTANT:
- If installing a new AC valve, be sure to replace with an identical part. IAC valve pintle shape and diameter are designed for the specific application.

Measure (If Installing a New IAC Valve)
- Distance between tip of IAC valve pintle and mounting surface.
- If greater than 28 mm, use finger pressure to slowly retract the pintle. The force required to retract the pintle of a new valve will not cause damage to the valve.

INSTALLATION
1. IAC valve assembly (75) and gasket (76).

Tighten
- IAC valve to 18.0 N.m (13 lb.ft.).
- Use a socket or box wrench on valve hex.
2. AC valve electrical connector.
3. Air cleaner assembly.
4. Reset IAC valve pintle position:
a. Depress accelerator pedal slightly.
b. Start and run engine for five seconds.
c. Turn ignition "OFF" for ten seconds.
d. Restart engine and check for proper idle operation.
