The EGR valve isn't the only component of your vehicle's emission system that affects performance, but it's one that affects it very dramatically. In extreme cases, a faulty EGR valve can entirely sideline your Frontier. EGR valves work to recirculate unburned fuel before it gets to the exhaust, so even if your vehicle is still working, its power and fuel efficiency will both be affected dramatically until the work is done.
