Idle Speed/Throttle Actuator - Electronic: Service and Repair
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.
