I had an EGR valve not working properly, and I must disagree with the idea that it is a '99 so just replace it...I mean if that was the reasoning get a new car. The whole thing is a 99. I have the same exact car, and, I removed it and used choke/carb cleaner and screw drivers plus a little O-ring pick set of like hooked and sharper tools to scrape it clean and spray it, and scrape it and so forth. She is back to driving like a champ. I have a 1999 Saturn SL2 Manual. I am making a youtube video of the fix, I'll post its link when its up.

You can find these are much cheaper on ebay compared to a dealer or parts store. While the movement of the plunger may well be stuck, on mine the gasket was burned through between the passages. On a car this old, replace the whole thing and clean off the old gasket residue before reinstalling your new EGR.

Take it off and look at it internally, See if you can move the diaphragm if not then it needs replacement. But you should just go ahead and replace it anyways since it is a 99 it would just be worth it

93 3003 MERCEDES 2.8 DIDNT PASS SMOG NO CHECK ENG LIGHT ON SMOG GUY SAID EGR STUCK IDILES A LITTLE ROUGH BUT RUNS GOOD AT HIGH SPEEDS WHAT DO I DO?


run the fault codes to ensure that the EGR valve is faulty. Engine lights to not always come on unless there is something drastic going on with the engine /gearbox so that you can stop the car before damage is done.

Won't pass smog when it should...


Just because the car seems to run well, does not mean the emissions are within spec. For example, you could be running a little rich and the car will start and run great, but the exhaust is not within code.
What you can do is take it to a "smog shop", that is a repair shop with the proper equipment to diagnose the problem. If the testing is simply the reading of the on board computer codes, then most any place can read those, but you need an experinced mech to know what to do about it. May need an exhaust gas analyzer to physically sample and analyse the gasses. For the actual test, as long as the computer says all is fine, usually, you're good to go.
If the computer looses power any saved run data will be lost and must be re-accumulated to pass the smog test. A few hours to a day is usually enough run time to accumulate enough data.

I have a 2001 suzuki xl7, I replaced egr unit and installed new pvc valve. Still shows error code P0400. Why won't it pass deq?


You may have a EGR valve plugged exhaust gas passage, so when it is opened the systems computer doesn't see any change in the O2 signal voltage. To check this manually pull open the EGR valve, the engine should run very rough and will stall out most times, if you open the valve up and see no change in the engine idle the passages are plugged with carbon and must be cleaned. As long as you have this EGR problem the car will not pass smog.

Removal of egr valve in 93 cadillac, didn't pass smog, want to check egr valve


I would not remove it unless its bad. did it not pass smog because of that? the valve either good or bad and does not need to be removed to check it. it either opens or it doesnt with vacuum applied.

1986 Toyota new rebuilt motor won't pass smog at


It depends which emission you are failing on but I suspect that it is either CO or NOx. If it is NOx, then it is quite possible that you have a problem with your EGR valve or the ignition timing is incorrect. If you failed CO, you may have a dirty air filter or indeed, a bad carb, but I would need to know the actual gas and readings to be certain.

SMOG test passed ALL except "NOx" results were 696 Limit is 585. Any easy fixes ??


I've had good luck using CRC's "Guaranteed to pass" fuel system cleaner. Follow the directions exactly. It should bring all the smog numbers down--perhaps get your NOx number low enough.

If the EGR valve is not working properly, it will lead to high NOx. Check for a leaky vacuum diaphragm on this valve. It will not only keep the EGR from working when it should, but also lead to a lean mixture that burns hotter, thus generating even more NOx.

Check for vacuum leaks. Any extra air that makes the mixture lean will contribute to high combustion temperatures and high NOx--even if the EGR valve is working.

Finally, if those steps don't work, it could be your catalytic converter is getting old and inefficient. Don't be surprised if you need a new 'cat.

I have a 1998 dodge stratus and the code 403 egr flow cicuit malfunction comes up how can i fix this problem so i can pass inspection


Check all vacuum lines to the EGR valve, the EGR valve is between the intake and the exhaust, EGR stands for Exhaust Gas Recirulator valve. It must be able to flow properly in order to pass emissions anyway if they do a smog test.

High nox fail smog test any remedies? 99


NOX is created when the internal combustion temperature gets to high.The egr system uses burnt exhaust gases to line to cylinder walls.The purpose of this is decrease internal combustion temperature therefore reducing the amount of NOX created.Would look to a possible egr malfunction usually they will trigger the check engine light but not always.The 4.3L has been known to have issues with carbon buil up in the egr and the egr pintle not open and closing properly.

Bad EGR


Yes you can by-pass the EGR valve. The only problem is that when it comes down to getting it smogged it will not pass. So that should be considered before bypassing the system. If you still want to by-pass the system let me know and I will tell you how to do it. But again it will not pass smog without it working properly
