The engine control unit (ECU) commands the valve to meter the air that bypasses the throttle plate. It adjusts idle airflow during warm-up, during load changes such as A/C or power steering use, and on deceleration. This is designed to keep idle speed consistent and help prevent stalling.
Signs an IAC valve may need replacing include erratic idle speed, stalling, hard starting or an illuminated check engine light. These symptoms can have other causes, so diagnose the system first. If a faulty or sticking IAC valve is the cause, this valve replaces it. The listed applications use one valve. Country of origin: China.
