If you have a P0401 code from a CEL, the first thing is to check the EGR vacuum modulator. It is a little well usually next to the EGR. Pop the cap off and dust the little sponge inside. Sometimes this gets stuffed up with carbon particles and causes recirculation problems. You should clean the tubes hooked to it while you are there. Reset the code and see if the light comes back.
Replacing the EGR is not a tidy job. It is an expensive part to replace and you will disconnect the three hoses and dismantle it from engine by two nuts. Save it for the later if the previous trick fails to work.

The egr valve is located at the end of a hose that plugs into youe valve cover. It is pushed right into a rubber grommet that is located in one of the valve covers. I hope this helps. don.t forget to rate my nswer, thanks

The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. This results in a cooler, more complete burn of the fuel which decreases you car's noxious emissions by prohibiting the formation of some harmful gases.
The EGR valve is vital to your car's emission controls.
When the EGR valve goes bad, it must be replaced - it cannot be repaired.
The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on accelertaion.
The only short term problem is a decrease in gas mileage - but it should really be replaced before sensors become sooted or your cat. convertor gets overworked prematurely.
