That code is for the heater circuit o2 sensor, bank 2 sensor 1. That shouldn't be fixed with custom tune. There's likely a fault in the heater circuit wiring or the sensor itself. Custom tunes to turn of o2 sensors are only necessary if you're running no cats. The codes that would set would be for banks 1 and 2, sensors 2, not 1.
