in the exhaust manifold. is there any place to buy a used one?
The upstream oxygen sensor is located in the exhaust pipe between the exhaust manifold and the catalytic converter The downstream oxygen sensor is located at the catalytic converter outlet
there are two located on the y pipe prior too the pre cats and one more in the rear converter
bank 2 is on the left side of the engine or the side closest to the front of the vehicle. So the oxygen sensor would be on the exhaust coming from the left side.
Answer I found this great site about Nissan O2 and its location to fix with diagrams!
where is bank one sensor 1 located on 2001 maxima Bank 1 sensor 1 is located at the upper front left hand side of the motor. My 01 20th anniversary edition has 4 sensors. Just recently replaced all 4.
Bank one is generally the cylinder number one side or drivers side on many cars, sensor 2 would be the rear, or post catalytic converter side of the bank 1 manifold.

I'm getting terrible gas mileage and i need to know how many are in the vehicle.
If the Nissan truck is either a V6 or a V8, the oxygen sensor will be located in the manifold. Sometimes it will be placed just below the manifold.
