2006 Durango p0404 code back after changing EGR valve
 

I'm looking for some help. About 4 months ago, I got a P0404 code on my 2006 Durango 5.7 hemi. After researching, I replaced the EGR valve and code cleared and all was good. Code has now reappeared. Just curious, did I jump to wrong conclusion on the EGR, has it just failed again, or did I perhaps miss something the first time? Thoughts would be appreciated. Thanks!

was it difficult to replace? I am in need of the same repair

No, not hard at all. Mine was located up front under the air cleaner, passenger side. Just a couple bolts. It is one of those blind feel kind of things, but not hard at all.
