Nissan Maxima EGR Valve reduces nitrogen oxide emissions by sending a portion of exhaust gas back to the intake stream to lower combustion temperature. The EGR Valve is installed in a passage linking the exhaust to the intake manifold. It opens during steady cruising or light acceleration. When the valve opens, the nitrogen and oxygen molecules in the air-fuel mixture are displaced by non-combustible exhaust gases. This causes the peak temperature to drop, resulting in less NOx being emitted. In the idle position, wide open throttle, and cold engine situations, the device stays closed to prevent rough running and stalling. A Nissan Maxima engine may be equipped with either a vacuum operated diaphragm style EGR Valve or an electronically driven EGR Valve depending on system design that regulates EGR flow. If the flow is incorrect, a Nissan Maxima can develop spark knock or hesitation or trigger diagnostic codes that set off the check engine light. If the EGR Valve sticks because of carbon buildup, it could cause performance problems and an emissions test failure. Through inspection of the emission system, Nissan Maxima, the valve is able to operate and continue to meet pollution regulations.
