How to check and replace a damaged Idle Air Control (IAC) valve on Ford Expedition?

The engine's minimum idle speed is factory-set and usually not adjustable. If idle issues occur, check the Idle Control Valve (ICV), which regulates engine idle speed. The ICV, controlled by voltage pulses from the PCM, is located on the throttle body. If these checks show a problem, replace the ICV.

Ford Expedition Idle Control Valve

In Ford Expedition vehicles, the Idle Control Valve is a very important component in because it has the function of controlling the speed of the idling engine by controlling the amount of air passing through the flap. This electro mechanically operated device is referred to as idle air control (IAC) actuator which helps to keep the engine idle and also not stall even under varying loads, with the help of engine control unit (ECU). In the IAC actuator, there is usually a linear servo motor that translates a plunger movement which controls the airflow so as to sustain the engine idling speed. Although built to last these valves can prove problematic; for instance, dirt or dust can cause them to jam leading to erratic idling. Cleaning is one of the maintenance practices that might be useful to perform on the Idle Control Valve to guarantee performance in Ford Expedition vehicles for the entirety of its working life span.
