Welcome to my youtube channel Crazy Mech-Tech, this video is about maintenance/cleaning of an idle air control actuator or idle air control valve (IAC actuator/valve) which is a device commonly used in fuel injected vehicles to control the engine's idling rotational speed or RPM. In CARBURETTED vehicles a similar device known as an idle speed control actuator is used. The IAC actuator is an electrically controlled device, which gets its input from the vehicle's engine control unit (ECU). The actuator is fitted such that it either bypasses the throttle or operates the throttle butterfly valve directly.
Although the IAC is supposed to last the vehicle's lifetime, various reasons may cause it to fail/malfunction prematurely. The most common failure mode is partial/complete jamming of the actuator (due to dirt/dust or even oil) where it cannot be smoothly controlled. The result is an engine that fails to maintain idle RPM and frequently stalls. A jammed actuator may be freed simply by cleaning it. However an actuator that has stopped working due to a fault in its servomotor will need replacement. Air leaks in either the stepper housing or pipes will cause elevated idle RPM.
