P0057 Oxygen sensor heater control circuit low (Bank 2 Sensor 2)

Bank 1 is where cylinder 1 is located , the other side becomes Bank 2. When it comes to Sensor, Sensor 1 are upstream or engine management sensor, Sensor 2 are downstream or catalytic monitor sensor. What you have is a downstream 02 sensor at Bank 2

From under the vehicle view, this is Bank 2 Sensor 2
