A stepper motor is controlled by the onboard computer. The computer moves the pintle in and out of an opening that bypasses the throttle blade. This allows the computer to precisely control idle speed when varying loads are placed on the engine. Symptoms of failure include engine stalling, surging, poor idle conditions, and or a check engine light. Check for proper operation with each tune-up. Replace when trouble codes indicate failure. Walker Products began supplying the fuel system needs of the automotive industry in 1946.

The Idle Air Control valve is an electronic device used by the engine control module (ECM) to control engine idle speed. The control valve will be mounted in the throttle body on the engine and allows air to bypass the throttle plate during a closed throttle condition. The valve is also used on many applications to control vehicle speed when the vehicle cruise control is engaged, the ECM will allow air to bypass the throttle plate while monitoring vehicle speed and other signal inputs.
