Where is Bank 2 on a Nissan Maxima?
The bank 2 sensor 1 O2 is located in the exhaust manifold (or just under the flange for the y-pipe) in the manifold closest to the radiator.
Which side of the exhaust is Bank 2?
Bank 1 and bank 2 simply refer to either side of the engine. Check your owner’s manual or a service manual for a positive location of bank 1 and bank 2. Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine.
Is Bank 2 front or rear?
Bank 2 is the front bank closest to the radiator.
Is Bank 2 up or downstream?
Bank 2 Sensor 2 means Downstream Left/Front.
How many O2 sensors does Nissan Maxima have?
The standard 2.5L 4Cylinder motor will have three oxygen sensors total. The upgraded 4.0L V6 engine is going to have a total of four oxygen sensors on the vehicle. No matter which model You have they will both have two on the catalytic converter.

What position is bank 2 sensor 2?
All oxygen sensors are located on the exhaust system, Bank 2 for your engine will be the bank of cylinders closest to the front of the car. Sensor 2 will be the second oxygen sensor downstream on that side of the exhaust pipes, after the catalytic converter.
Where is the bank 2 sensor?
On straight four and six cylinder engines, there is only one bank of cylinders. So all of the oxygen sensors will be bank 1. The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2.
