EGR Valve

[_VVTi_]

Few days ago my engine light came on, and I took it to Fountain Tire to give it a check, they got a code related to EGR valve. So they cleaned the EGR valve and reset the computer. Then the next afternoon the engine light came on again. Took it back to Fountain Tire, and they recommended me to replace the EGR valve, which cost $400CDN...

My question is, is the EGR valve something really critical to the engine?
I know what the EGR does, but I don't know if it will do damage at the moment.

Thanks for a replies.

What I would do if I were you is replace it with a USED one as they don't break that often. The EGR is important as otherwise you might have several problems like engine running too rich / poor,... Your engine will run but not in ideal conditions without it.

its not really a problem till you have to smog check it

so....... should i worry??
but haha... the light went off today afternoon while i was driving, and it hasn't been on since then... should i still get it checked and see if there's a code registered in my ECU?

Since i got my short ram intake, my check engine light comes on and off periodically. took it to my mechanic and he said it was the EGR Valve...said it would run fine without it, although i agree it probably wont run at its best. I could use an answer to this same question - what would yall recommend?

the car will run fine without the egr valve, since some people actually block it off. but if you are an environmentalist or someone who really cares about the environment, then fix it. the car will not run its best as of gas milage, etc... but i will rather just fix it since it doesnt break often. oh yeah, there is no way you will pass smog with a busted egr... at least not here in cali

egr stands for exhaust gas recirculation. for example, on the japanese 3vzfe motor there is no egr valve, so on the highway it is not recirculating any exhaust back into the intake.

some will say on the highway having the egr blocked yields more performance... but yes you will fail smog.

Some peole do remove it and block them indeed but there is a difference between such a device and a leaking egr : because air is leaking so I guess the air / fuel ratio can't be the same

are there any pics of the EGR valve?

for what its worth that is also the function of the egr.

I'm also having trouble with my EGR valve, and hotter combustion temps are something that's worrying me at the moment, because I've read that having an EGR malfunction can cause engine ping/knock, & is a source of a lot of trouble.

those crazy egr valves

i removed my EGR system and my Charcoal Canister... car runs great... since the exhaust went back into the intake, the intake has felt cool to the touch instead of hot... i just put in a block-off plate and plugged some things up, and my car runs awsome...

You can do what I did and just take that damn light bulb out that illuminates the check engine light.

[Porkch0p220]

i dont think that was such a good idea, if another problem accurse.... you will never know

yesterday i put the car up on ramps to see where egr vsv is. very hard to reach.

The one on the back of the intake manifold?

The EGR valve is on intake manifold but the VSV is on the head below the manifold. That is the case on 1990 Celica 5S-FE. I gonna put mine on firewall after the swap.
