The Exhaust Gas Recirculation (EGR) valve is an important part of the exhaust circulation system of a vehicle. EGR valves have been in use in the United States since the 1960s, when car companies were seeking ways to increase the efficiency of vehicles while also decreasing pollution. When the EGR valve is clogged or malfunctioning, it can cause irregularities in engine performance such as rough idling or valve knock, indicating that the EGR valve should be inspected.
