Bank 2 Sensor 1 Location??

[e5game]

got a p0051 and going to be replacing o2 sensor located in bank2 sensor1, is bank 2 (cylinders 2, 4, and 6) located on the passenger's side or the driver's side? And just to verify one more time, this is the sensor pre-cat, correct?

Thanks in advance to anyone that helps me out on this one :keyboard:
