2005 Ram 1500 4wd HEMI PO406 - EGR

exhaust gas recirculation sensor A circuit high. you can find out about this at autozone.com. they have assistance in troubleshooting, and locations of parts.

Check the voltage at the EGR solenoid and ground. Remove the EGR valve and clean the carbon buildup out of it or replace it altogether. A new EGR valve will run you about $60 from the dealer.

The EGR on my 05 Hemi Durango is located on the passenger side front of the engine near the head.

I would bet your Ram is the same or close to it.

Dodge/Chrysler EGR valves are known to be unreliable. The one on my wife's 05 Grand Caravan died in the 40k miles range.

They are not really serviceable. The usual fix is replacement. Part will be between $50 and $150 depending on where you get it. Installation most of the time is 2-4 bolts and the harness.

hemi engine?

EGR valves are usually on top of the intake but with the Hemi plastic cover you cannot see much. It will have a single vacuum line running to it.

I just took mine to the auto part store to find out. From what they told me its the little box on top of the Hemi Engine cover. They said I have to go to the dealer to get the part though.

404 & 406 appear EGR related. Check all hoses & connections at EGR. My guess is once EGR is fixed 430 will disappear. I believe EGR is just below & to left of alternator, 2 small bolts holding on.
