On a 2001 Chevrolet Cavalier with a 2.2L OHV engine, the Idle Air Control (IAC) valve is typically located on the
throttle body. It's a small, usually cylindrical, valve mounted directly to the throttle body itself. You'll likely find it on the side of the throttle body, facing the engine bay. You may need to remove some air intake components to get a clear view.
Because there can be slight variations in placement depending on specific manufacturing details, a visual inspection with the air intake partially disassembled is recommended. A repair manual specific to your vehicle year and engine is the best resource for precise location and any special removal procedures.
