In the engine fuse / relay box use the cover as a map, fuse ENG 1 which is a 20 amp fuse, If you have bank 1 sensor 2 heater code you will need to check for power and ground at this 02 sensor, Other than that 02 sensor do degrade and wear out over time and it is the heater circuit that wears out first.
