IDLE AIR CONTROL (IAC)
Operation Overview
The Idle Air Control (IAC) is used to stabilize the idle quality of
the engine at cold start-up and after warm-up operations.
Mounted on the throttle body, the IAC contains 1 stepper motor
which receives varying voltage signal pulses from the ECU.
These pulses determine the IAC plunger setting, thereby
controlling the amount of air bypassing the closed throttle body
for idle control. If the IAC is disconnected or inoperative, it will
remain at it’s last operated position.
IAC Test
The IAC is a non-serviceable item. If it is faulty, it must be
replaced. It can be ‘bench tested’ using the following method:
Set your meter to read Ohms. Check the resistance values at each
of the following pin locations of the IAC. If any of the readings
are out of specification, replace the IAC.
