EGR

[Conn SVX]

Were is the EGR valve ? How do I clean it . Where can I get one?

[THE NEW GUY]

is behind the passenger side cilinders, atached to the block. It have two steel pipes connected with two M6 screws each. one of the pipes comes from the exhaust and the other goes to the admission on the same cyl 5. Do not touch it unless you have ECU codes about it. You can even replace it with the one on the legacy outback.

I am getting a check engine light flash on every so often. PO said it has been doing it for over a year. He was getting an EGR code . He cleaned it and it went away. The car passed emissions 3 weeks ago with the light on. what else causes the check engine light . It has all new Co sensors

Make a new code check. If it's still the egr problem, change the EGR with one from a legacy outback. it fits good but the orientation for the vacuum hese change, so you will need a new hose. Change all the vacuum hoses compromised with the EGR valve. there's another vacuum activated device on top of the EGR valve. It controls the EGR valve too. It have 03 vacuum connections, (P, R and Q) replace that device also. that also can be replaced by the newer outback.

Mine has a intermittent CEL for ERG code also.
Mine also passed CT emissions with the bad EGR code.
Makes me wonder if the EGR thing is even needed...

P.S. If I drive on the highway at constant speed the CEL tends to turn off.

I was wondering if the EGR be removed and replaced with a resistor or something that give the everythings ok message to the ECU, instead of replacing it?
Or does it actually serve a purpose?

my EGR is bad too, but my check engine light only turns on when the engine is warm. drives me nuts.

[Jake@FAPFab]

switching to an early 92 ecu will get rid of the CEL
that ecu does not have an egr function

Went to check the code and by the time I got home, it was gone . Seems to come on after150 miles of driving and go off after 20 miles or so. passed CT emissions with flying colors and I don't have to go back for 2 years .Once more after that and then I don't ever have to get it checked .

Shouldn't it store the last code even if the CEL is off?

Does that mean that the EGR will not work, stay closed all the time, or just the ECU wont check the EGR for a code?

I am less concerned with the CEL than I am about the fact it may be stuck open dumping hot exhaust gas into the engine all the time.

Man mine was replaced before I bought it and it is still on. I hope I can clean it and get my code off. I have to have CEL off in Texas.

[Conn SVX]

Well I can see I am not the only one in this same boat/ Mine is off again . It came on for 2 miles last night .

I am in the same situation, I never see the check engine light until warm weather arrives. After a drive somewhere then a park and return I get the light, check code 32, 34, 32 is oxygen sensor but its fine, 34 is egr solinoid or circut. Last time I drove I did a little experiment when I stopped I popped the hood while having lunch, then closed it and started the car....no CE, ya did this little trick 2 more time worked both times, then stopped for 5 minutes without opening the hood, the CE was back, its a heat thing! The way I understand things is the egr valve is mechanical, the egr solinoid is an electrical valve that the ecu checks for proper value, if its to hot/old/broken/disconnected/whatever, the ecu is not happy. So some day when I pull the intake manifold off for fun I will change that part along with all those hoses, thats my 2cents.Good day to all..............G

exactly the same with me! it doesn't matter how warm it is, as long as the engine is cool, the light stays off. makes sense why. if i park for a couple hours and the dial goes all the way cold, no CEL. how big/expensive/difficult of a deal is it to clean or replace this thing? it's the only thing that bothers me

[Conn SVX]

So we are back to the original question. Mine has no rime or reason. I had no CEL I was in a Car show for 3 hours with the HOOD open. I started the car and CEL popped on .As soon as the temp needle moved it went off. If i go through the trouble of taking it off i am going to swap it out . The PO has cleaned it a few times already and it lasts 150 miles or so
