Bank 2 Sensor 1 is typically located on the exhaust system of a vehicle, specifically on the side of the engine that does not contain cylinder number one. It is positioned before the catalytic converter and is responsible for monitoring the oxygen content in the exhaust gases, helping to optimize fuel efficiency and emissions. This sensor plays a crucial role in the vehicle's engine management system.

Passenger side is bank 2. Sensor 1 is in front of the Cat., and sensor 2 is in back of the Cat.

Typically, bank1 sensor1 and bank2 sensor1 refer to different sensors in a dual-bank engine configuration, such as those found in V6 or V8 engines. While they may serve similar functions, such as measuring exhaust gas composition or temperature, they often have distinct part numbers and specifications tailored to their specific locations. It's essential to consult the vehicle's service manual or parts catalog to determine compatibility and whether they are interchangeable.

On a 2009 Chevy Traverse, the oxygen sensor bank 2 sensor 1 is located on the exhaust system, specifically on the exhaust manifold or just downstream of it on the exhaust pipe. Bank 2 refers to the side of the engine that is opposite to bank 1, which is typically the side with the cylinder 1. To access it, you may need to lift the vehicle and work from underneath or remove some engine covers or components for better access.
