Smooth out an erratic idle with the Standard Ignition Idle Air Control Valve (MPN AC240). It installs as a direct-fit replacement for the 2000-2004 Ford Focus [L4-2.0L], slotting in where the original idle air control valve was located.
An idle air control valve meters the volume of air that bypasses the closed throttle plate, allowing the engine control module to regulate engine speed at idle. If a failed idle air control valve is the cause of your idle trouble, this replaces it.
- Function: controls the bypass airflow around the throttle plate so the PCM can maintain the commanded idle speed.
- Fitment: engineered for the listed 2000-2004 Ford Focus [L4-2.0L] applications.
- Replacement: serves as a direct-fit swap for the original idle air control valve on those vehicles.
Common signs the idle air control valve may need replacing include a rough or surging idle, stalling at stops, an unusually high or low idle, and hard starting. These symptoms can have other causes, so diagnose the source before replacing.
Manufacturer part number: AC240.
