This air pump check valve prevents exhaust gases from entering the air injection system. If the air injection check valve develops issues, then the check engine light can illuminate. This issue will cause your vehicle to release more emissions and potentially damage the AIR system. Replace your old malfunctioning valve to get your car emissions compliant again.
