I brought my car for a dam sticker today and it fail the emission test. It did not pass the CO and the HC, both during the cruise portion of the test. When I got the read out of what the problem might be i noticed that both had the same problem in common, the O2 sensor were saying to be checked. I would replace the sensor if i knew where it was, because it was only 20 bucks. I read how to replace it and that seemed like something i would be able to do. I need to know where the sensor is or if you think i need to check something else feel free to suggest something else. Thanks

only because I'm getting tired of people say "do a " and not helping the person any at all... (not talking about five7 lol, he was nice and did a search FOR you )

the O2 sensor is attached to the driver side exhaust manifold. It ought to be the only sensor in there. Its down a bit, right after the "log".

If you go to a part's store and buy a O2 sensor tool then that will make your life a TON easier. Also if you have a breaker bar and and a extension then you can get it out in like 2 minutes.

My advice: spend the extra money on these parts since you'll never know when you'll have to use them again! a 6 inch extension and breaker bar I have used about 12 times since I bought it, if not more. And that is less than 5 months ago.

 

sorry sellmanb
but i did a search and nothing came up. I posted the same topic twice so i might get the answer. Some times if you post it in two places you get the answer and sometimes people are helpful and give even more infromation to help people that have a hard tiime a little extra help. Thank you for the help
