What is the function of the valve known as the Idle speed control valve?

The Idle Control Valve, controlled by the Engine Control Module (ECM), maintains a steady idle speed during engine warm-up and when using the air conditioner. It functions as a controlled air bleed, bypassing air around the closed throttle valve. The Idle Control Valve can be tested with diagnostic equipment or a digital ohmmeter. Replacement depends on the engine model.
