What's up guys, the other day my CEL came on in my new-used truck...lol the same day I bought it. I was pissed, but I got it checked up at autozone and it got coded P0406, the EGR valve. So no biggie, I figured I would just try to clean it first, and clear it and then see if it came back on and if it did THEN I would just replace it.

Anyway, yesterday after work I go out to my truck and notice that my CEL turned itself off? lol. I didn't even know that it could do that, but it just wasn't on anymore.


What do you guys think happened?

 

just replace it and be done. you can only clean so much if its bad its bad cleaning will not help

 

Yeah, I guess you're right lol.

I just thought it was weird that the CEL just turned off on it's own yesterday?

 

it only takes 2 faults so throw a code ...you need a new egr ..how many miles???

 

Anywhere after about 40k miles you can expect the EGR valve to go bad on a hemi.

 

77k.

Yeah I'll just order one and replace it and clean the throttle body while I'm in there like Silver said.

How much should I expect to pay for one of these? Nick said someone got one for only 40 /w shipping cuz he ordered it online?

 

My egr code would go on for about a week and then go off..... it did this a few times and was pretty annoying because the 2 times i was about to go to autozone to get the code, it was off. I tried cleaning mine just to try it but i had already ordered the part. Easiest fix i'd say and my truck ran noticeably smoother and the overhead says my gas mileage is a little better also... but im sure my was gunked up real good because i drove mine for awhile before replacing it with the light on

 

rockauto.com and its under emissions

 

Cool deal man, good to know I might be getting better mileage out of this as well haha.

and thanks for the link nick.


Shame you cant come out tonight. There's gonna be kinda a lot of people comin over haha. Gotta get like 4 30 packs

 

Have you tried a local parts store? I can get one at advance for around 40 with no shipping.
