Check Engine Light

Maintenance/Repairs

So my exhaust system snapped right before the cat. converter and the check engine light went on (02 Sensor). I took it to the shop and they were able to successfully weld the it back on.

They cleared the code and told me that it had registered the code for 200 miles. I only saw the check engine light for 50 miles before bringing it to the shop.

Well now the check engine light is on again, I am pretty sure its the O2 sensor.

I was wondering if I needed to do one of a few things:

a) Since I have only driven 20 miles after the repair should I give it a few weeks and see if it goes away?

b) Replace the proper O2 sensor because the one I currently have has too much carbon deposited on it to give it a proper reading?

or

c) Go back to the shop so they can check their work since they might have missed a spot. (How likely is that?)
