There should be two Oxygen sensors; the one that wears out most frequently is installed in the exhaust manifold, close to where the exhaust pipe connects. The second Oxygen sensor should be behind the catalytic converter.

There are two.
To change the oxygen sensors on a 2000 Infiniti QX4, first, ensure the vehicle is parked on a level surface and the engine is cool. Locate the oxygen sensors; there are typically two upstream (before the catalytic converter) and one or two downstream (after the converter). Disconnect the electrical connectors, use a wrench or socket to unscrew the old sensors, and install the new ones by reversing the process. Finally, reconnect the electrical connectors and clear any diagnostic trouble codes if necessary.
There are total 4 O2 sensors. You can buy all 4 from Oxygen Geek and will cost about $260.
