So as titled says my car is giving me a P0050 code and then the info it provides is "H02S Heater Control Circuit Bank 2 Sensor 1"

Where is this located? Also could someone link me to a part (canadian)? I am getting so confused whether is upstream or downstream and don't wanna buy the wrong part.

personally - I would have loved to hear question like "how can I find it out".... but here you go:
bank 2 is left side of the car.
sensor 1 is first(from engine). it looks like this.

part number - 22641AA25A
(any subaru dealership)
