What Is An Air Pump Check Valve

The air pump check valve is responsible for keeping your exhaust from exhausting. It is responsible for improving your fuel economy and reducing emissions by acting as a secondary air injection system that allows air to enter but closes to prevent exhaust from escaping. Some vehicles may have multiple valves or contain an air diverter valve,to handle the same job. With frequent use, it often degrades as a result of facing high pressure and hot temperatures constantly.
