P0400

[00tothemax]

my CEL went off, kept coming back, and I got the code from a local autozone as P0400.I was told I'd need to replace my EGR valve, which I've found for $130 at a parts store. Can anyone give me a clue as to where it is located within the engine. Is this something I can replace myself? Otherwise, around how much would a local shop charge to replace this?

Thanks in advanced

400 at dealer 250-300 at local mechanic. Not exactly sure where it is located. I think you have to pull the intake manifold. I also assumed you have a'00 maxima. Prices are from dealer and mechanic in Olympia Wa. prices vary by region of the U.S.A.

thanks, yeah ive got a 2000sucks the work is twice the part money wise.im from new york

Sorry, New York is more expensive than here. It wont break any thing to run it with a bad EGR it just kills your mileage. So I guess with the horrible gas prices it's cheaper to fix it. What do you pay for a gallon in NY? Here it's 3.28 for a gal o' premium.

I had that code on my '98 and when I cleared it the light stayed off. That was about a month ago.

+1 try Mav's idea before you shell out the bucks for a new EGR valve. Good thinking Mav' !!!

Hey, as cheap as I am.. When the CEL comes on, the first thing I do is check it and clear it... If it comes back on, and keeps coming back on, then I will fix it. I don't have the money at the moment to keep fixing things that can wait.

Mav, I'm not busting your chops, that really was a good idea and I will probably use it the next time I get a CEL.

It's cool man, I took it exactly as you meant to say it. I know what you meant, I was just saying I am cheap as hell and I do that with everything I have. If I get a light, I clear it and fix it only if it shows back up a couple times.

Glad I could help.. I wonder if that fixed the OP's light...

to me!

it comes back on within a couple of miles of driving.same code, I guess its time to change the egr valve

So... did you actually replace it? I have a 98 Max, getting the 0400 & 0325 codes. I'd like to fix them myself. I'm no mechanic, but I'm not necessarily afraid, either.

Can it be done by a diy'er? Does anyone know of an online Chilton's-esque site? Thanks!
