The Idle Control Valve in Saturn Ion is responsible for controlling the engine idle speed through the control of the airflow through the throttle plate. This is an electrically operated valve referred to as the idle air control valve or IAC for short and it is fitted to work with the engine control unit (ECU) in regulating engine idling to prevent stalling especially where the engine load is varying. The IAC actuator uses a linear servo motor to control airflow through the throttle body with a mechanically governed idle speed. At different times, different types of Idle Control Valves may have been used for the different Saturn Ion models, the only difference being the configuration of the actuator. These components are fairly robust, but they can fail in ways that cause the engine to idle erratically, for instance, due to jamming because of dirt or dust accumulation. Cleaning is also important in maintaining the Idle Control Valve in good condition to prevent the need for replacement because of a mechanical failure.
