AboutRoland Finston Expertise I take questions about domestic Chrysler-product front wheel drive cars and minivans for the years 1982-2000 based upon my experience and shop manuals. I don't have detailed information (e.g. manuals) nor expertise for Jeeps, trucks, SUV's, import vehicles, or for years more recent than 2000 (except Sebring/Stratus I have '03).
I am available to take a question between 8AM CT and 9PM CT, and attempt to provide an answer within 1 hour. If I am shown as "maxed out" try again later in the day as I add question opportunities one at a time so as to respond quickly, but I do have other responsibilities as well so may not be available for several hours at times. Try at 7PM CT as I will always be available for one question then.
There are answers to hundreds of Chrysler questions at your finger tips: click on "view past answers", one of which may be to your question as well; or put a few key words in the "search for" box, above.
Experience I have been a do-it-yourself auto hobbyist for 5 decades, and most recently have been concentrating on the various Chrysler Corporation domestic front wheel drive cars and vans. I have shop manuals and wiring diagrams for many models for the years '83-'00, as well as rear wheel drive cars for the early 80's. I enjoy analyzing problems that other Chrysler enthusiasts are having and sharing my information.

Question Hi,
I have a Dodge Grand Caravan whose 3 year warrenty expired in May this year, the check engine light has just on on at the end of June, the scanner outs out a code of p0404, which to do with the EGR valve out of range. Couple of things i would liek to know, one does the egr valve need replacing or not, if so where would I find the said egr valve and secondly is this considered part of the power train so that it w will still be covered.
I would appreciate any help or guidance.
Regards
Andy
Answer Hi Andy,
I would believe that this part is covered under either the powertrain warranty or the emission control system warranty that may be a federal requirement, but I am not an "expert" on the warranty matter. The egr is mounted on a smaller pipe that connects the right side exhaust manifold to the engine intake manifold and its purpose is to reduce tailpipe pollution. I suspect that it is not needing replacement but rather either cleaning of the stem where is moves in the valve body or correction of the wiring or vacuum connections to the valve. The computer has noticed that the valve is not working as expected, so a code has been set.
So I would not hesistate to take the vehicle to a dealer for a warranty repair. If they claim it is not covered, then you can check with the regional service manager of Chrysler or the federal National Highway Safety Adminiatration.
