What is the Exhaust Gas Recirculation/EGR Valve?

The EGR (Exhaust Gas Recirculation) valve assist lower the car’s exhaust emissions (gases from the tailpipe). It recirculates the part of the gasses coming out of the engine by putting in back into the intake manifold, where the engine can burn it again, thereby limiting the emissions.

The EGR valve is found in the engine compartment (underneath the hood). Most engines require exhaust gas recirculation to meet emissions standards. If the EGR valve has gone bad, the car will not pass emissions.
