The Jeep EGR valve is quite important to two vehicle systems, playing a role in the control of vehicle emissions as well as helping to maintain the efficiency of the ignition system. In most late model vehicles, the Jeep EGR valve is an electronic component, while in older model vehicles it is likely to function mechanically with a vacuum connection. In most vehicle models, the Jeep EGR valve is mounted to the intake manifold of the engine. The Jeep EGR valve helps to reduce the harmful emissions of the vehicle, quite important in these days of strict emissions regulations and vehicle emissions testing. By helping to prevent detonation, also called engine knock, the Jeep EGR valve helps to keep the engine operating at its best and the fuel mileage as high as it should be. Detonation can cause the engine to run very inefficiently, causing many performance problems in the vehicle. Among these is a loss of engine power, excess emission of pollution, rough running, and poor fuel economy. Detonation is also likely to cause damage to delicate engine parts if allowed to continue too long, leading to expensive and unnecessary repairs.
