Question about Nissan Maxima
This sensor would be in the right bank as you face the ngine from under the hood, it is the sensor before the catalytic converter in the exhaust pipe, u will need a 7/8" wrench or special O2 sensor socket to replace it, the tool type depends on how hard it is to remove, spray the threads with WD 40 before trying to remove. go to the link to see the oreintation of your engines cylinder banks, bank 2 has cylinder numbers 2, 4 ,6 in it.

bank 1 refers to the side of the engine that #1 cylinder is on , and sensor 2 refers to downstream , after the catalytic converter. , this link shows bank 1 on a 2001 nissan maxima V6 being on the firewall side . if you had a 4 cylinder it would be downstream after the catalytic converter .

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

bank 1 exhaust is the rear manifold towards the windshield side. Follow the exhaust down. There should be one oxygen sensor before the catalytic converter and a monitor after the catalytic converter. Be Careful.. they look the same.
