OBDII diagnostics code PO150

1996 Nissan Maxima
I used a OBDII diagnostics code reader on my car to determine why my Malfunction Indicator Light (MIL) is "ON". The code I retreived from the car's computer is PO150 which indicates that the O2 circuit bank 2, sensor 1 is malfunctioning. The car has three sensors of which two are called front heated oxygen sensors located on the exhaust manifolds and one is called rear heated oxygen sensor and is located to the rear of the catalyst. My question is... how do I determine which of these three sensors is the "bank 2, sensor 1" ???
Thanks in advance for any feedback.

Bank 2 is the side of the engine without cylinder 1. and sensor 1 is the sensor before the cat.

Bank 1 contains cylinder 1.
