1992 Camry LE 2.2 Failed NOx in Smog Test

[baadfish101]

Hey guys, looking for a little advice here. I just bought this Camry a few days ago, so I know nothing about its history, all I know is that it runs really good (180K miles) and everything seemed pretty straight on it, but then today it failed smog. If anyone can take a look at these results and lead me in the right direction to fixing the problem, I would be greatly appreciative, for I cant afford to pay a mechanic to diagnose the problem.
Here are the results:

you not only failed because of excessive NOx, but also because your Check Engine Light was on (error detected).

first scan the ECU with OBD scanner or jumper the terminals and read the code(s).

second, look into the EGR system, this is what helps reducing NOx if working correctly. other than that your catalytic converter(s) maybe on the way out.

also, next time you attempt testing for smog, drive the car for a minimum of 30 mins on highways before going to inspection station. if systems were not fully warmed up then the 3-way catalytic converter might have been working inefficiently.

changing oil also helps reduce emissions as well as running a tank of gas with a cleaning additive (e.g. Chevron Techron or CRC Emission Formula cleaner), but remember to drive it almost dry and then refill with fresh fuel BEFORE going to inspection station (with a fully warmed up car)

Yea I replaced the Check Engine Light bulb today, I was thinking of pulling the EGR valve and giving it a good cleaning.....I hope its not the Catalytic Converter....they are expensive Ive heard....ugh.

Oh and thx for the tips...I'll certainly make sure to do that before next check!

I thought CA law says when you buy a car, the seller is responsible for smog inspections. May be you bought it as a parts only car?

"When a used vehicle is sold in California, the seller is legally responsible for providing a smog certificate."

Thank you for that. Believe me, I wish I had paid better attention in the process of buying the car.....it has cost me too much already. Turns out, he (the seller) put a fake registration sticker on the licensce plate, and I ended up having to pay the DMV $220 for registration (pending smog) and late fees.

I tried calling him, because in all honesty, I just wanted to give him a piece of my mind, but when I call he doesnt answer. I dont know what recourse I could take, and whether it would be worth it anyways. I paid the guy $2000 for the car, and already Ive had to spend $220 on registration, $40 on a failed smog, $300 on new front axles, $350 on new tires, $60 for a window regulator, and I still need to get the A/C going. Its been a nightmare to say the least.
