Hello I have a 04 ram 1500 5.7 with a error code P0406 which is a EGR issue what most likely is the fix ?? Any help will be greatly appreciated.

 

Moving your post to the 3rd gen section for better exposure....DAVID

 

Replace the EGR valve....there is a write up on how to do it yourself:

Nice writeup Jnellydodge... can you update the links to the pics? I cant see em.

 

lol, I see you are in spanaway.


Well, I don't really have a good write up but I do have some pics of when I replaced mine.

before doing anything with it, i would try resetting the CEL and see if it comes back on. my cel popped on the 06 hemi last weekend and i got the "malfunctioning egr" code. i reset it and it hasnt come back on yet..tonight ill take it on a long ride and see if it comes back on. the egr looks easy as hell to change..right up front, top of the motor.

 

I have my own code reader and used it to reset the code to see if my ride really thought it was broke. The check engine light came back on within 10 miles of driving. I reconnected the reader and got the same P-0406 code. I take that as gospel to replace the EGR now hehe.

 

yea...I'd check out rockauto.com for a new one. It's hard to find one in advance/auto zone and then ur stuck with buying from the stealership

 

Can you repost the pictures to this thread? Pictures of the EGR valve and it placement.
Thanks

 

My thread still has pics in it. Should give you an idea. Also searching the website with "P0406" in the search box should pull up many more threads. Hope this helps! Also remember, my thread is only valid on the 5.7 engines. the 3.7 and 4.7 engines have different locations than the 5.7.
