You will be fine. This is the bank 1 sensor 1, o2 sensor code. Probably just needs this o2 sensor replaced. It will throw off your fuel economy some and you may get a little bit of rough running till replaced.
It will be ok. Check the fuses though, it is possible this circuit has a blown fuse! Look in ownwers manual, index in back of book, find fuses and see if it is one for the O2 Htr. This is the oxygen sensor heater circuit. (Possible!)
