I have a service engine light on my 1994 chevy camaro v6 3.4L car. I was told that It was the egr valve that needed to be replaced from the person I bought the car from. I am not sure If Its a hose that has a crack or what but I havent checked that out yet. The egr valve was replaced 30k miles ago. Should I clean or replace the valve along with the hose but then would I need a guy to turn off the light. It only comes on once In awhile but I am wondering how to replace the egr valve I have a general Idea but I was looking on youtube I couldnt find that great of a video.

 

you can clear the ses by unhooking your battery for several minutes. search around for a factory service manual. heres what they look like. this one is kinda spendy. should be able to find a set for 20 to 50 bucks in fair shape. 1994 Chevy Camaro Firebird Trans Am Service Manual Set on eBay!

 

what code # are you getting?

 

I wouldnt know what code Im getting. I bought this car then the guy said that the reason the light was on because the egr valve. I asked a thread a time back but there were people saying this car could get codes then others saying It couldnt read any. Idk what to tell you as far as a code.

 

heres some stuff for ya there are two codes for the 3.4 egr 74 and 75

 

Thanks I will see If that helps when I try to take the valve off. It will cost about 150 for the part. I am thinking I should buy that new. It comes with the gaskets.

 

It would be very smart of you to get the error code checked before replacing anything. Depending on the code, it could be the EGR valve itself, an EGR solenoid, or the related wiring circuit. You could be throwing money away replacing the EGR valve, if that isn't the actual culprit.

 

Alright when I get the left front tie rod end I will ask if they can read the code.
