See my profile. They screw in just like a spark plug.
However they have a wire to contend with, so they make a O2 tool, basically a spark plug socket with a cut-out down the side, for the wire to protrude out.
For hard to get to spots, other specialty sockets are available. Sometimes you can do it with a wrench or channel lock pliers.
Since I know little about your rig, I do not know how many you have and their locations. They are usually on the mandifold or exaust. Close to the engine. Or. Around the catylitic converter A manual would be a good investment.
When you purchase the O2, the part store guys are good about FREE CODING and which one. And where.
Please send back your results.
