Idle Air Control (IAC) Reset Procedure

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

Measure the distance between tip of IAC valve pintle and mounting flange. If greater than 28 mm, use ringer pressure to slowly retract the pintle. The force required to retract the pintle of a new valve will not cause damage to the valve.

Reset IAC valve pintle position:
a. Turn ignition "ON" for five seconds.
b. Turn ignition "OFF" for ten seconds.
c. Start engine, check for proper idle operation.
