2001 Sonata V6, Smog failed - high NOX

Hi

I just got SMOG checked on my Sonata V6 2001 and failed due to high NOx(reading-836 where average is around 18). I have 72K miles on the car and it just runs fine with no issues at all.

The manual & TSB says high NOx is due to the EGR malfunction, but I am not sure if the 2001 Sonata V6 has the EGR ?

Can someone pl tell me
1) if there an EGR in the car?
2) If yes, where is it?
3) If no, then what should I do to repair it and pass the smog.

Thanks
-p

    i am glad to hear tht athere is no egr valve in my honest opinion what i would do is take the car and have it hooked up to a diagnostic center cause there is no egr valve that means a that like u said you might have a catallaticv converter that is plugged up or you have a sensor that is malfunctioning and believe it or not i have had a gas cap fail and i failed smog that is why a diagnostic center would be able to give you the truth instesad of spending time and money that we all do not have lol any way keep me posted ok best regards mike

Check the ports if there is any carbon,I doubt it,
but you got to look
I would make sure you don't have overheating issues
That is the cause of NOX (High Combustion Temp)
Check fuel pressure
Use synthetic oil in engine
Check PCV Hoses etc

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.

1992 dodge stealth failed smog test with high NOx reading at idle. passed perfect at high rpm , failed at idle. hat causes a high NOx reading?


NOX is produced when cylinder temperatures exceed 2500 f.
Your vehicle has 2 ways to directly reduce NOX, EGR system, and catalytic converter, and also the cooling system indirectly.
Take a look at the EGR system, vacuum lines, pipes, and make sure the diaphragm moves. Disconnect the vacuum line, then push on the diaphragm and plug the hole (from vacuum line) when you release the diaphragm there should be vacuum. Also you may want to take it out and give the EGR passages and EGR valve a good cleaning, with some type of carbon cleaner like carb cleaner.

Failed smog


We had to have the calatic converter replaced. We did this after doing an oil change, air filter change, and new spark plugs and still hadn't passed smog. After changing the calatic converter it passed smog with scores of 25.

My ''nox'' emissions was to high on smog test?


Usually a high NOx reading on gasoline vehicles is caused by a bad catalytic converter on your exhaust. I would suggest having this checked out before you try the test again. Hope this helps.
