There are four oxygen sensor in a Maxima 2001. See Nissanhelp.com for a diagram location.
I'm getting terrible gas mileage and i need to know how many are in the vehicle.
There are two oxygen sensors on a Nissan Sentra. This vehicle is an ultra-low emission car, thus needing only two oxygen sensors.
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
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 drivers side, sensor 2 is rear O2 sensor(oxygen sensors are screwed into exhaust pipes)
There is 2 oxygen sensors on the 2002 Nissen altima
All O2 sensors are threaded into the exhaust system at various points.

Go to the dealer and ask one of the guys if they can print it out. It should be one page. If you have California emissions you have four sensors, two in the front and two by the firewall. It's easy just look under your car and you'll see them..
one is in the exhaust manifold, one goes into converter
the part no. are 64,2387,79856
The 2000 Nissan Pathfinder has a total of four oxygen sensors - two before the catalytic converter, and two after the converter. The front sensors have 3-wires, and the rear sensors have 4-wires. For a good quality OE-style sensor, they'll cost around $100 each.
This particular model has two oxygen sensors . The first is on the intake manifold facing the radiator and the other is under the vehicle on the exhaust pipe .
And they are expensive to replace... (i replaced one @ $400)
in the exhaust manifold. is there any place to buy a used one?
There are 4 oxygen sensor on Maxima 1997. 1.- Fronto Sensor Driver Side 2.- Front Sensor Passenger Side. 3.- Two rear sensors: first one located on Catalytic Converter and other one after it.
GO to www.courtesyparts.com. You should be abble to find a diagram and the parts there. There is probably 3 total. One will probably at or near the back of the cat and the other two up on the head pipe (1 on the left and 1 on the right).
Assuming you have the V-6 engine, it has two downstream (after the cats) O2 sensors and two upstream (before the cats) Air/Fuel Ratio Sensors. So the answer to your question is two O2 sensors.
Applied to : 2000-2002 Maxima P1167 (Bank 2) Ho2S2 (Rear) (High Voltage Monitoring) Replace Oxygen Sensor... Check out this site..http://www.nissanhelp.com/Ownership/Bulletins/Nissan/2002/NTB02-051.htm
Usually oxygen sensors are what would be screwed into the exhaust manifold.Usually oxygen sensors are what would be screwed into the exhaust manifold.
Just one and its located right in the middle of the front of the motor.
