What if your 2004 dodge ram 2500 5.7 hemi 4 x 4 does not have an EGR valve, but is sometimes stalls and sluggish, but always restarts, I was told the EGR valve but this truck does not have one

SOURCE: P0406 Code

It is for the Exhaust Gas Recirculation (EGR) valve.

Hey greenlee99, your best bet would be to grab one these manuals so that you have pictures and diagrams along with step by step instructions. It will tell you what tools and parts you need. Can't go wrong with having it.

Have not replaced the EGR on my 04 Durango as of yet, but if you look into the the passenger side front fenderwell you will see part of it. Usually 2-4 bolts and the harness connector are all that is required.

Chrysler EGR valves are not known for their reliability.

First, without meaning to be a ****, I would like to say a few things to help keep you from spending your hard-earned cash that you probably cannot afford to throw away.

1. Your vehicle is equipped with an electronically controlled EGR Solenoid Valve. Failure of these valves are EXTREMELY RARE (Although many parts outlets sell thousands of them based on their "FREE" diagnostics).
2. If you do not know where the EGR valve is, then you could not possibly have tested it properly. If you have not tested it, then you cannot possibly know for certain that your vehicle needs an EGR Valve to fix whatever problem you are attempting to repair.
3. MOST EGR system failure codes are NOT caused by the EGR Valve itself. The most likely cause of an EGR code is clogged EGR ports (Which can be fixed with a gasket, a little elbow grease, and a can of carb cleaner). EGR control circuits i.e. wires, connectors, etc. run a close second in the code-causing category.

Now that I have done my preaching (and hopefully, helped to keep you from wasting your money), the answer to your question is that the EGR Solenoid Valve is located on the right front of your engine. (See picture)

Most likely U Joints in the front axles. These will only turn in 4 wheel drive.
