Mopar 4861552AC Idle Air Control Valve Assembly

The 4861552AC linear idle air control valve (IACV) solenoid is an engine management component designed to regulate bypass airflow at idle, maintaining stable engine speed under varying load conditions. It operates on a 12V DC electrical system with a square female connector housing two male blade terminals. The valve body is constructed from zinc die-casting for durability and thermal stability. This part supersedes earlier revisions 4861552AA and 4861552AB and is a direct OEM replacement for Mopar-branded vehicles. Cross-reference interchange numbers include Standard Motor Products AC482, Wells AC356, SMP GT7610-124, and aftermarket equivalents from Crown Automotive (CWA-4861552AC), ECCPP, and other suppliers. The component mounts directly to the throttle body with no gasket or mounting hardware included. Typical service weight is 0.23 kg (0.5 lbs).
