Features & Benefits:

Inspect valve for rust and/or exhaust gas residue. With engine running, check valve for exhaust flow on the pump side of the valve. Replace valve if exhaust is present.

The Air Pump Check Valve is a one-way air flow control valve in the air supply tube to the exhaust system. These valves prevent exhaust gas backflow into the air pump system which would damage other components of the system.
A bad or failing Air Pump Check Valve can cause under-hood exhaust leak or noise. Exhaust bypassing the valve can lead to Air Pump failure.
