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.
The HO2S Bank 1 Sensor 1 is located on the exhaust manifold nearest to the front of the car. The Bank 1 Sensor 2 is located on the exhaust pipe before the catalytic converter and after the pipe from the bank 1 and bank 2 exhaust manifolds meet.
On a 2005 Nissan Maxima where is the Camshaft Position Sensor (Bank 1) located?
Bank 1 is the bank of the engine that contains #1 cylinder. Bank 2 is the other bank. Sensor 1 is located before the catalytic converter. Sensor 2 is located after the cat converter.
Bank 1 is located on the same side as cylinder #1. The spark plug wires are numbered.
Bank one are before the Cat and bank 2 are after the Cat.
Bank # 1 is the passenger side of the engine
the bank 1 sensor 1 is located in the header right before the cat ans is easy to access from the front of the car. bank 2 sensor 2 is located after the cat and the heat shield can make it difficult to turn
P0135 = Bank 1, sensor 1
Bank 1 is the drivers side of the motor, making bank 2 the passenger side of the engine. Bank 1 Sensor 1 will be located before the Catalytic converter, Bank 1 Sensor 2 would be located after the Cat. This is of course assuming your vehicle is equipped with the California emissions having a total of 4 O2 sensors.
cylinder #1 is the first cylinder from the passenger's side on the rear bank.
Bank 1 sensor 1 was the upstream 02 sensor located before the catalytic con on my 03.
