  • I replaced the egr valve and the map sensor, but I still get codes P0405, P0406. It also has a lot of roughness in the engine. What could be the cause of this?

    The exhaust gas recirculation (EGR) valve in your 1999 Mazda Miata is an exhaust intake regulator that's mounted to the intake manifold of the engine block. The EGR is designed to regulate the mixture of fuel and exhaust (oxygen) by maintaining normal combustion while improving fuel efficiency. Originally introduced in the early 1960s, this device has evolved as a vital part in improving automotive fuel efficiency and reducing smog. A malfunctioning EGR valve is often signaled by the check engine light coming on. Replacing the EGR valve in the Miata is a moderately easy repair to perform.

  • Got a replacement EGR valve after getting error code. After a week of running with no issue, all of a
    sudden it sounded like an exhaust leak and the smell of engine exhaust came from the engine
    compartment. Since the installation of the EGR valve was simple, 4 bolts with the proper gaskets, i'm
    wondering if this EGR valve is bad.

    This video shows how to replace the EGR valve in a 2005 Lincoln LS 3.9L. Since it sits right up on the top near the front of the car, it is not too hard to replace and should be able to be replaced by someone with a minimal amount of mechanical skills. I tried to clean out the valve but it kept triggering the check engine light so now it is time for a replacement. It cost about $95 for the new valve after tax.

    Failure to repair or replace the EGR valve will not lead to a life threatening condition, although it will reduce the life of your car and increase the potential emissions. Especially in areas which require smog testing, an automobile with a malfunctioning EGR valve may not pass.
