Bank 2 Sensor 1 is on the driver side - follow the right side of the engine down the headers which attaches to the catalytic converter. The o2 Sensor you're asking about (Bank 2 Sensor 1) is before the Catalytic. The o2 Sensor after the Catalytic is Bank 2 Sensor 2. Bank 1 Sensor 1 is on the passenger side as well as Bank 1 Sensor 2.
I have a 2003 cadillac ccar and my car was throwing smoke out the back pipe.so I tod it has something to do with the gadgets but I knowrest that there's a sensor broken that runs down it looks like a light bow but is not and seens is just by were I put the oil on the bottom my car started to throw smoke
SOURCE: where are bank 1 sensor 1, bank 2 sensor 1, bank 1
bank one sensor 1 is the bank of cylinders that number 1 spark plug is located in, bank 2 the other side, this assumes u have a V8, the sensor one location is the sensors that are BEFORE THE CATALYTIC CONVERTER, the sensors referred to as sensor 2 are after the ones AFTER THE CATALYTIC CONVERTER IN THE EXHAUST SYSTEM.

Four wires (circuits) are used on each O2 sensor:
O2S Sensor removal
Never apply any type of grease to the oxygen
sensor electrical connector, or attempt any soldering of the sensor
wiring harness.
WARNING: THE EXHAUST MANIFOLD, EXHAUST PIPES AND
CATALYTIC CONVERTER(S) BECOME VERY HOT DURING ENGINE OPERATION. ALLOW
ENGINE TO COOL BEFORE REMOVING OXYGEN SENSOR.
1. Raise and support vehicle.
2. Disconnect O2S pigtail harness from main
wiring harness.
3. If equipped, disconnect sensor wire harness
mounting clips from engine or body.
CAUTION: When disconnecting sensor electrical
connector, do not pull directly on wire going into sensor.
4. Remove O2S sensor with an oxygen sensor
removal and installation tool.
02S Sensor installation
Threads of new oxygen sensors are factory coated
with anti-seize compound to aid in removal. DO NOT add any additional
anti-seize compound to threads of a new oxygen sensor.
1. Install O2S sensor. Tighten to 22 ft. lbs. (30
N·m) torque.
2. Connect O2S sensor wire connector to main
wiring harness.
3. If equipped, connect sensor wire harness
mounting clips to engine or body. When Equipped: The O2S pigtail harness
must be clipped and/or bolted back to their original positions on
engine or body to prevent mechanical damage to wiring.
Hope thats help (remember comment and rated this).
