The Idle Air Control Valve (IAC valve), or idle actuator, is an electronically controlled valve mounted on the throttle body to regulate bypass airflow into the intake manifold. It typically consists of a DC motor, lead screw, and optical encoder to precisely adjust the valve position. During idle conditions—such as when parked or in neutral—the ECU dynamically adjusts the IAC valve opening based on engine load changes (like AC activation or steering) to maintain smooth idle, prevent stalling, and ensure efficient combustion with controlled tailpipe emissions. Common issues include carbon buildup causing valve sticking, unstable idle, shaking, or stalling; thorough cleaning or replacement usually restores proper function.
