Without knowing the model & the description of your vehicle DTC'S its very hard to say what could be wrong.

Yankee,

Hopefully youve rectified your sensor error by now but if you havent, check before and after your CC. A lot of people think they only have 1 O2 sensor but many cars especially nowadays have 2. One before the Catalytic Convertor and another after it.

If your using after market sensors like bosch. Make sure you get the wiring right if it has multiple leads. You may need an adapter.
