Bank 2 sensor 2 refers to the oxygen sensor on the passenger side of the exhaust system and after the catalytic converter. heater circuit is the oxygen sensor or the wiring going to it, it is what is called a heated oxygen sensor. Google image search oxygen sensor and that is what it looks like, and they can be a bear to get out.
Most oxygen sensors are heated oxygen sensors.

Location of sensor
Newer oxygen sensors are heated for accuracy. If the heater element goes bad the oxygen sensor doesn't work and needs to be replaced. If you have an oxygen sensor heater malfunction, it just means that the oxygen sensor has failed.
