Oxygen sensors simply unplug and screw out. They may be a little difficult to reach, and are usually well rusted in place, but there is nothing mysterious about removing them.
What is a carbon dioxide sensor?

A CO2 probe sensor measures gaseous carbon dioxide. It comes in two ranges, 0 to 10,000 ppm and 0 to 100,000 ppm.
it will blow up
I don't believe there is a Carbon Dioxide sensor on any vehicle. Answer I work at advance auto parts and have NEVER heard of one. Newer vehicles do have O2 sensors.
disconnect the attached wire and unscrew the sensor. there is a gel that should be applied to the sensor before you replace it.
Co2(s)~Co2(g)
You cannot repair an O2 sensor. Replace it.
CO2 is quite heavier than air. You should mount a sensor as close to the floor as possible. Also, put them in any holes or pits which could collect CO2.
Are you sure you mean the co2 sensor? There is an o2 sensor on the exhaust in front of the catalyser, on later cars there are two sensors, the other being behind the cat. These are also called Lambda sensors. Hope this helps.
