I have actually replaced the EGR valve 4 times but each time the check engine light come on again even though ns cleared every one of the codes. The code presented each time is “P0404 EXHAUST GAS RECIRCULATION regulate CIRCUIT RANGE/PERFORMANCE”I was told that i should have the computer system flashed. Possibly I should simply disconnect the battery for a minute?
replaced the EGR valve 4 times however each time the examine engine light come on again
What were the codes that resulted in you to replace the EGR valve… four times? article those right here so we deserve to advise. Additionally post the engine dimension and type in her Ram and also how plenty of miles top top it.

I think that you have actually conclusively proven the error codes room not cause by the EGR valve.
Each time my code reader shows the EGR valve is bad. Ns don’t psychic the password number. My van is a 2004 Dodge ram 1500 SLT, 5.7 Hemi, 4 door, 4WD. I am likewise told that some vehicles won’t accept anything however OEM components so that will certainly be my next move. This last time I replaced it (Saturday) the van ran far better with the bad valve.
I am additionally told that part vehicles won’t expropriate anything yet OEM components so that will certainly be my next move.
Dodge does not make ERG valves , lock buy them native a supplier . Also the explain that part vehicles won’t accept anything however OEM components is nonsense.
Each time my password reader shows the EGR valve is bad.
I yes, really don’t think there is such a code. For this reason tell us, what to be the actual code. Over there are several that relate come EGR. V the right information you might get a correct diagnosis, and correct treatment plan.
Well in addition to every the various other requests already requested… i should add that the success of your EGR valve procedure (as much as your computer system is concerned) is not only made decision by even if it is the valve actually opens and closes…it is additionally dependent upon vacuum (older layout EGR’s), strength to the electromagnet (newer format EGR’s), the computer control… AND additionally the EGR pathway which is the EGR tube and or the pathways it offers in stimulate to permit the engine come inhale its very own tail pipe emissions. Those pathways need to be open up and totally free flowing through no carbon buildup or blockage. Her EGR valve may actually be functioning insofar as it opens and closes once asked to do so…but if the pathways room blocked it will certainly report that the EGR is faulty.
Engine codes rarely point to source cause… much an ext often they allude you in the general area come look into not a “be all finish all” that what part failed and also what the repair is. Think of them more as a suggestion and also not a silver- bullet form of thing.
SInce girlfriend have an ext than among these points floating around… you have the right to leave among them bolted in location on the engine and also hookup an additional one electrically and vaccum way to view if it opens and also closes at different times together you operation the engine. If you notice the valve is actually operating…then your problem will be through the exhaust gas pathways the the EGR valve is trying to connect and disconnect.
This thought process should acquire you closer come the yes, really repair.
The code that keeps coming up is “P0404 EXHAUST GAS RECIRCULATION control CIRCUIT RANGE/PERFORMANCE”
There’s a problem with the circuit for the EGR valve.
Not through the EGR valve itself.

Thank you for the info, that aided a lot!

I evaluate the thorough response! I now have much more of one idea just how to go around diagnosing the issue.
allpar.com is a site dedicated to Chrysler vehicles. Several different forums, as well as lots of elevator info, space there. You might find assist there. Ns have, number of times, for questions around my former and also present Plymouth and Chrysler minivans.
Good luck and please keep us informed.
I was told that ns should have actually the computer system flashed. Probably I should simply disconnect the battery because that a minute?
Who called you that the computer needed reflashed?
Some auto components stores deserve to do this- my components Plus can, and also it’s much less than $100. Not sure if this will aid your worry or not, but this doesn’t have to be a dealer just thing.Disconnecting your battery will certainly not aid this issue.

The engine computer system monitors the EGR to make sure it is functioning correctly. The computer regulates the EGR to open a an accurate amount for the particular operating condition, then the computer verifies the actually opens that amount by reading a sensor within the EGR. Ns think the trouble is that the computer is commanding the EGR to open, but not obtaining the appropriate sensor reading that the actually has opened. Yes a fifty percent dozen or much more reasons why that can happens. Due to the fact that replacing the EGR ass’y didn’t carry out the trick, most most likely a difficulty in the wiring between the computer and also the EGR ass’y. Could be damaged wires, faulty connector, brief circuit, or faulty ground. Less likely, the computer could be faulty. A shop would probably start by measure the voltage of the 5 volt recommendation to the position sensor. This problem is walk to require a ideal diagnosis ns expect. The change this replace that method on a guess, while it can eventually work, may cause you to operation out the money before you run out of guesses.
