Answer 1

P0050 - 02 sensor Bank 2 Sensor 1 heater circuit high

Circuit high are disconnection of that sensor , either the connection of the sensor is poorly connected or the sensor itself has failed. There is no fuse for the 02 sensor, The location of this sensor is where cylinder 2 is located being Sensor 1 this is the upstream 02 sensor.
