I use to have an 89 Max. The Ox Sensor was connected to the engine filter lid. Since we have junk yards in my area, I bought a used one and just removed that top part of the filser off.

What problems will a bad speed sensor cause on a 1999 Nissan Maxima
To change the oxygen sensor on a 1996 Nissan Maxima, first, locate the sensor, typically found on the exhaust manifold or the catalytic converter. Disconnect the negative battery cable, then unplug the old sensor's electrical connector. Use an oxygen sensor socket or a wrench to remove the old sensor, and install the new one by threading it in and tightening it securely. Finally, reconnect the electrical connector and the battery cable before starting the engine to ensure proper function.
where is the camshaft sensor in a 96 nissan maxima 3.0
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
Did you figure out where this sensor is located
bank one is drivers side, sensor 2 is rear O2 sensor(oxygen sensors are screwed into exhaust pipes)
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!
its in the distrubator
