How can I tell?
How can I tell if my egr is functioning properly. besides the SES light, is there some type of test I can do myself? Want to make sure it is functioning right before getting my smog test. The Stealership wants $45.00 just to test it......

On older style EGR valves you could see the rod move. Once warmed up, you would simply rev the engine up to around 1,500 or 2,000 rpm, hold it for a few seconds and then let off. Upon letting off, you could see the rod move if the EGR was functioning correctly. Not sure if you can even visualize it on the newer EGR valves. A malfunctioning EGR should trigger the SES.

If your EGR was not working, your PCM will know, and it will turn on the check engine light. The PCM tests it occasionally.

O I C! So, that was your code, for an EGR issue?

Well then, if you reinstall it, then drive it for a couple weeks or so before the emissions check and the light remains off, you should be golden. As in, you live in the Golden State, right? My brother once corrected my wife when we visited CA in July, she remarked that everything is so brown. He kind of laughed, and said "it's golden, not brown."

Not any easy way that I know of. It's a 5 wire connector to the EGR, right? If you had access to wiring diagrams, you could ground the proper wire to see if the engine starts to sound like a mean cam at idle. What about this, AutoZone or some places like that will do a free scan. Tell them that your light came on, and ask if any codes are stored. Also, since your light won't come on, won't that be an instant fail in Cali? It should come on for a 2 second bulb check....

Well, maybe you could go somewhere where they could do a loaded emissions check on your vehicle before you go for the emissions check? They can use an exhaust probe that would tell if your NOX is too high. Not free, but it should tell you whether or not your EGR is functioning. NOX would be too high if the EGR isn't working correct or the 3-way convertor is not working either.

I'm not sure if a tech 2 can read the egr pintle position or not. I'm assuming it can and that's why the dealership said they could test it. If cutlass doesn't reply shoot him a PM and ask him if they can read the pintle position. I wouldn't think the dmv would check if it's actually working though.... I would think they'd just look for the codes and what not and call it good if there are none. Not sure though cuz I've never had to do the e-check.....thank god.

I talked to the guy that is going to do the smog here in town he said that i could stop by and he would run the test to let me know if i will fail or not. He's not going to do the actual smog check just going to hook something up to let me know so that's better then nothing i think.~Chris

yep...that sounds like the way to go. See if you can talk ($$$$$) him into checking the box that says "passed" on it while you're there.
