IAC valve

The **IAC valve** (Idle Air Control valve) is a crucial component in modern vehicles’ engine management systems. It regulates the engine’s idle speed by controlling the amount of air that bypasses the throttle plate. Proper functioning of the IAC valve ensures smooth idling, optimal engine performance, and prevents stalling during idle or low-speed conditions.
