Hi! Welcome to JustAnswer. Thanks for coming! I'm Ron and I'll be working with you on your question today.

There are 2 oxygen sensors on this vehicle. Did the p-code tell you the correct one to replace?

Thanks for holding!

Ok- There are a few different options here. First- you can remove the "NEG" cable from the battery for a minimum of five minutes. If you use this method, you will need to drive the vehicle roughly 50-75 miles. If the engine light does not come back... you're good to go. If it does- the oxygen sensor was not the problem.

Another option- simply drive the vehicle. Roughly 50-75 miles and the on-board computer will recognize the problem has been fixed, and will turn the light out by itself.

Last option- Most local big-chain parts stores, like AutoZone, will clear the codes for Free (except in California) right in their parking lot. Again, with this method, you'll need to drive 50-75 miles to see if the light comes back or not before you know if the problem is solved.

No, If I would have gotten the book with the car I would Have known to drive it and it will let me know. thanks not sure five was what I wanted to pay. I new I could take it in and they could clear the code. Byron ******I learned a lesson today.

IF the light does come back... or if you still have the p-code and want me to double-check that the correct sensor was replaced... you can always reply back and I can be of some help!
