The secondary air injection system is an emissions system equipped on many road going vehicles. It is composed of several components that work together to reduce the vehicleâs tailpipe emissions. One of these components is the air pump check valve. The air pump check valve is the valve that allows air supplied from the air pump to be pumped into the exhaust stream to reduce hydrocarbon and carbon monoxide tailpipe emissions.
