EGR Error Code

When I put on my o/r xpipe and cat back i my check engine light went on. I have MIL's for the o2 sensors. The code is P0401. It says that my EGR valve doesn't have sufficient flow. Do i have an exhaust lead somewhere in one of the headers or has my EGR just gone bad?

Re: EGR Error Code

That code is usually associated with the DPFE sensor going bad.
It's about a $60 part from Ford.

Re: EGR Error Code

I'm pretty sure it stands for Differential Pressure Feedback (Emissions)? sensor. I'm not really sure about the "E". Anyway it's a very easily accessible sensor near your EGR valve that is part of the emissions system. (sorry i don't have a pic) When my car threw that code i changed my egr valve first and then found out it wasn't the valve because the problem didn't go away. Then i changed the sensor and everything was fine again. BTW the new sensor from ford was a different shape than the one on my car due to a design change but it does the same thing.

Re: EGR Error Code

how hard is it to put on the DPFE sensor and does it go on the actual EGR valve? In other words, where does it actually go?

I bought mine from him for 15 bucks as well. You will need a tune to tell your computer to not permanently throw an engine code however.

Re: EGR Error Code

I made my own, but as stated you will need to turn the EGR off in your EEC/tune

About 6 inches to the right of the EGR valve right on top. It's a simple connector and two vacuum lines. (2-minute fix) . The sensor looks like one of the images in this thread ....

Re: EGR Error Code

i have the Xcal 2. Isn't that supposed to permanantly remove that code. I noticed that it goes away for a while but it keeps coming back.

Re: EGR Error Code

Not if you just read the codes & clear them.
You need to have it turned off in your tune.
