Code P0404

[Louie]

After filling up the other day my check engine light came on. Nothing seemed different when it did. I went to take it to the dealer and on the way the light went off. Last night while driving home from work it came on again. No change in performance that I can tell. I had the codes read today and it shows P0404 which I see is a EGR Valve. I was looking around alittle and see this might be covered under some federal emission warranty. My Truck is a 2005 RAM 1500 5.7 with 45,691 miles. If not under warranty anyone have an idea of the cost I am looking at.
Thanks for your help.

If you have the Hemi, you can about bet the valve itself is bad. I'm not sure if the warranty will cover it but it certainly won't hurt to ask. I think the valve runs about $150 (ballpark) for the valve and it's something you can easily change yourself.

Yes it's the Hemi. I am not much of a mechanic so I was thinking of taking it in. What all is involved with changing it out ? Is the 150 just for the part ? or is that an estimate of part and labor at the dealer. One last question, Is it ok to drive for a day or two before I can get it fixed ?
Thanks

Swapping it is a matter of removing a few bolts. If you decide to do it yourself, I'll post a how-to. The ballpark price I mentioned is for the part only and it will be ok to drive for a few days.

Dont forget to clean the return tube to the intake as well with some Brakeclean....

If you could post a how to that would be great. I went out to look at it. It does not seem like much. A metal tube bolted to it. I am guessing remove the two bolts connecting it to the metal tube and its off. Also what about the check engine light, do I need to go to a auto store to get it reset ?
Thanks for the help guys

REMOVAL - 5.7L




The electronic EGR valve and solenoid assembly (3) is attached to the front of the right cylinder head (1). An exhaust gas routing tube connects the EGR valve to the intake manifold.

1. Use a diagnostic scan tool to record any DTC's (Diagnostic Trouble Codes).
2. Disconnect and isolate the negative battery cable.
   
   
3. Disconnect electrical connector (1) from EGR solenoid (2).
4. Remove two bolts (3) connecting EGR tube (4) to valve assembly.
5. Remove gasket located between EGR tube flange and EGR valve assembly.
   
   
6. Remove two mounting bolts (2).
7. Separate valve assembly (3) from cylinder head (1).
8. Remove and discard metal gasket located between cylinder head and valve assembly.

Looks simple enough, My one question is, the first step (# Use a diagnostic scan tool to record any DTC's (Diagnostic Trouble Codes). Is this what I did to get P0404 or is this something I need to hook up to the EGR wires.
Thanks
PS does the valve come with the gasket, seals or do I need to purchase them also.

Is this the steel tube connecting to it ? Do I need to take the whole tube off to do this. Also you mentioned brake cleaner, Just squirt it in ?
Sorry for all the questions, and thanks again.

Yeah, take it off, clean the inside real good, use the little straw that comes with it to squirt it in the tube
