Where is my o2 sensor failed my emission test
So my jeep was fixed by my mechanic fixed the drive shaft and had to replace two o2 sensors. I still have the check engine light on and he said for me to drive the truck as I do lately because he had to reset the computer and that way I can take it to the emissions. I never heard of that please let me know your thoughts.

Yes you will need to drive te vehicle to set the readiness monitors. CEL must be cleared to go away, for most codes.

Yes really.
You had said before he thought it might be an issue, so what's the big surprise here?
He's diagnosing the issue, and sometimes to do that you need to follow a path. Sounds to me like he's following the right path, taking care of smaller, inexpensive items first, and going from there. Sometimes automotive work isn't cut and dry, as a matter of fact, just the opposite. Usually one problem has many different factors to it. Calm down. He's doing the right thing by checking the low cost ones first, and believe it or not, he's doing that for your benefit. Always check the easy stuff first, as it's usually the least expensive.
Also, you have never posted any info on your ride...what year, what config, etc....it will help others here in trying to diagnose your issue.
