The Bank 1 Sensor 2 for a 2002 Nissan I35 is typically located on the exhaust system, downstream of the catalytic converter on the driver's side. It monitors the efficiency of the catalytic converter and helps adjust the engine's air-fuel mixture. Unfortunately, I can't provide diagrams, but you can find detailed illustrations in the vehicle’s service manual or online repair guides.
The bank 1 sensor 1 oxygen sensor on a 2002 Honda Accord is located on the header. It is right next to the sensor circuit.
This tells you which oxygen sensor is out, look at your vehicle diagram to see where this sensor is located.
Bank 1 sensor 1 was the upstream 02 sensor located before the catalytic con on my 03.
There is no bank two on this van.
Bank 1 would be the bank of cylinders that contain cylinder number 1. Bank 1 on the 3.9 would be the bank of cylinders located on the drivers side of the engine. Bank 1 sensor 2 would be the O2 sensor located after the catalytic converter.
There are 2 catalytic converters on a V8 2002 Toyota Tundra. Bank 1 is the manifold and cat on the drivers side and bank 2 is the manifold and cat on the passenger side.

The Bank 1 Sensor 2 (O2 sensor) on a 2002 Infiniti I35 is located downstream of the catalytic converter on the driver's side of the vehicle. It is positioned on the exhaust system, typically near the rear of the catalytic converter. Unfortunately, I can't provide a diagram, but you can usually find visual references in repair manuals or online forums dedicated to automotive repair.
Bank 2 locates on the opposite side of the cylinder # 1 and the sensor 1 is locates in the front
Bank # 1 is the passenger side of the engine Sensor # 1 is before the catalytic converter ( upstream ) Sensor # 2 is after the catalytic converter ( downstream )
Bank 1 sensor 1 is closest to the firewall and located just below the exaust manifold. Easiest to change from under car.
On a 2002 Ford E-150 : Bank 1 is the passenger side of the engine ( V6 and V8 engines ) Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter ( upstream sensor )
