Details Idle Air Control (IAC)
The idle actuator, also known as Idle Air Control – IAC and stepper motor, controls the rotation of the engine under idle conditions.
This “valve” is controlled by the Electronic Control Unit (ECU) and has a stepper motor that, depending on the engine load, increases or decreases the passage of air to the intake manifold through a deviation called bypass.
Under idle conditions, the position of the obturator is calculated based on the voltage signals, the engine coolant temperature (ECT), and the manifold absolute pressure (MAP).
The idle actuator is found in the throttle body, usually fixed by two screws or snapped-in.
