EGR Valve failures are pretty rare. It's really unlikely that your EGR valve has anything to do with your engine smoking. The smoke is more likely to be caused by bad valve seals worn piston rings, a leaking injector, a leaking fuel pressure regulator, or a blown head gasket. The Check Engine Light being on is anybody's guess until you ask your engine computer why it turned the light on. Who knows? There might even be a fault code in there that may lead you to the cause of the smoking problem.
Your egr is what recycles exhaust gases back to your combustion chamber to lower emissions. does it smoke from the tail pipe?? if so what color?? white can mean coolant in the combustion chamber.. Black can mean oil getting burned in the combustion chamber... I would take it in to the shop to get the codes read...
SOURCE: How do you replace the egr valve on a 300
Heat up the exhaust pipe to egr with torch and spray with knockitloose or wd40 when not hot. Then remove that pipe. Then remove vacuum hose and the 2 bolts that hold it on.
Take your car to the nearest auto parts store and ask them to read and erase your trouble codes. As soon as you throw another code get them to read it again to verify which code is alerting you. Remember that just replacing a part is not always a solution. A egr is not too expensive and easily changed by someone handy. Buy a haynes repair manual for around $25. It's a good investment and will walk you through most repairs. It will also give you a basic understanding of what could be wrong with your car so that you will npt be taken advantage of by an unscrupulous mechanic .
