There are two oxygen sensors on a Nissan Sentra. This vehicle is an ultra-low emission car, thus needing only two oxygen sensors.
You need to take a wrench to loosen the oxygen sensor, then you will need to disconnect the cord. Once you have done that you will then pull out the old oxygen sensor.
The 'oxygen sensor'may need to be replaced on '96 Sentra when the check engine light comes on. The should be replaced on the '96 Sentra every 100k miles for better fuel efficiency and to protect the converter.
Catalytic converter I think The 02 Sentra doesn't have a "regular" catalytic converter, its an all in one manifold converter assembly. *There are 4, they are located in the exhaust manifold. On the 02 Sentra 1.8 there are two wiring harnesses that have blue plugs and two that have green. Those are the harnesses for the Oxygen sensors. Follow the harness down the manifold and that's where they are located.
Water cannot be divided by oxygen.
Oxygen cannot absorb UV-B, and ozone can.
The fuel of the Apollo spacecraft was a mixture of oxygen and nitrogen.

Oxygen
Oxygen cannot be broken into two atoms unless it is an oxygen compound of oxygen. Oxygen is an element, therefore made up of atoms, and therefore atoms cannot be broken down into more atoms.
The are two o2 sensors in an 04 Sentra. One is called the front sensor, and it is in the engine compartment, in the exhaust manifold. The other, the rear one, is in the exhaust pipe under the car, past the catalytic converter.
