Kind of depends on how many miles you got on the car. I'm no mechanic but I have changed a couple of O2 sensors on my cars before. Usually when the code goes just means you need to replace it. If not, your gas mileage is just a little worse than it should be.

Probably wouldn't be to hard for you to change either. Just go to autozone and they sell a special socket that is used to pull it out of the exhaust. It just connects to a socket wrench. Sensor may be a little expensive though. Maybe 70-100 bux, dunno just ballpark. But I have changed them on a couple different cars. Not sure but I would believe your car would have 2 of them, so better to do both, than just one.

If you do do it yourself, be sure to warm the car up first before trying to pry them out. They can be a b*&%h to get out. Just be sure to not burn yourself.
