If you have an OBDII code scanner, you can use it to read and clear the codes and turn off the CEL.
Don't assume the problem is an O2 sensor. A check engine light can be lit for many reasons. You need to have the codes scanned with a scanner, and post it here if you need help troubleshooting it.

Yes, there are many "o2 codes", but only a few indicate o2 failure
You need a scanner to erase the codes, but some will clear up themselves after you fix the problem
The battery disconnect is not suppose to work (to erase codes) on this vehicle
