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.
