A secondary air injection check valve is a one-way valve. It lets air from the air pump pass through toward the exhaust side and is designed to block exhaust gases from flowing back into the pump and its hoses. This part is listed under both names: Secondary Air Injection Pump Check Valve and Air Cleaner Check Valve.
Signs this valve may need replacing include burned or discolored air hoses, an exhaust leak sound or smell near the valve, or a secondary air system fault on vehicles that monitor it. These symptoms can have other causes, so diagnose the secondary air system first. If a failed check valve is the cause, the AV7T replaces it.
Sold individually as one valve, and the number used varies by application. Country of origin: Mexico. See the "Vehicles it fits" section for the full fitment list with engine codes.
