I changed my O2 sensor (bank 2 sensor 1) with no issues. However when I cranked it and let it run there was white smoke coming from the area of the sensor. I drove it around for about 10 minutes and still had this smoke. Previous to changing the sensor there was no smoke. Could this be WD40 burnoff or is there something on the new sensor that will burn off when it gets to temperature the first time.

Yea, you're just buning off WD40 and what ever grease you got on the new sensor with your hands. Heat it up all the way and it will be fine.
