I pulled my OBDII codes for my car, and it said "O2 Sensor heater circuit malfunction bank 1 sensor 1" and the same thing for "bank 1 sensor 2". I have been searching around for which bank is which, but I found nothing. Obviously I have a 6 cylinder, otherwise I wouldn't be having this issue. I would appreciate actual help, not people who are guessing based on what they think would make the most sense.

I was asking more which side is bank 1 and which is bank 2. Through searching I already KNEW the right and left, I need to know which bank is one and which is two.

Right bank = Bank 1 = firewall side of the engine = cyls 1, 3, 5
Left bank = Bank 2 = radiator side of the engine = cyls 2, 4, 6
