Mercury Grand Marquis EGR Valve

The EGR Valve in Mercury Grand Marquis vehicles regulates the circulation of fumes back to the chamber aiming at giving minimal air pollination. This exercise is known as Exhaust Gas Recirculation (EGR) where some of the published exhaust gas is again fed into the cylinder, thus minimizing peak temperatures and therefore NOx formation. The EGR technology over the years has evolved from simple orifice jets to the EGR valves controlled by some of the engine conditions; the current EGR systems utilize backpressure transducers for optimal EGR flow. Uninformed though, while EGR has been known to very helpful in reducing direct emissions, some of today's cars specifically the Chrysler Pentastar 3.6 does not use EGR, at least not in its engine design. Simple tasks like washing or even changing the clogged EGR valves' need to be performed from time to time for the smooth working and efficient results.

We provide a wide range of Mercury Grand Marquis EGR Valve at the best prices possible. If you need Mercury Grand Marquis EGR Valve, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.

    E5PZ-9H473-B
    Q: What is the purpose of the EGR system and EGR Valve on Mercury Grand Marquis?
    A: The EGR system reduces NOx emissions with two different systems. The Electronic Exhaust Gas Recirculation and the Pressure Feedback EGR. The EGR valve is controlled by a solenoid and the PCM. To check, perform a leakage test and clean the ports. The system uses an Electronic Vacuum Regulator to control exhaust gas flow. Check the voltage and resistance of the regulator and the EGR valve position sensor and replace it or regulator if needed.
