No O2 sensor listed in the FSM. WT?

Have an '02 Taurus that just rolled over 100k so I'm looking to change out all the O2 sensors before the weather gets too cold. I go to look up oxygen sensor in the old FSM to see what this is gonna look like and I can't find the term 'oxygen sensor' listed anywhere. Not in either the Fuel System or Exhaust System sections or in the back index. The closest it's referenced in one of the two previously mentioned sections is something like a 'catalytic monitor.' And nowhere can I find the procedure for changing them out.

Am I missing something here?

Not sure what service manual you have, or what engine you have, but I have seen them listed in the Emission Controls section, or similar.

Are you running a V6? If so I wanted to warn you they take two different spark plugs, as I learned recently.

02 is a v6 only change over year. Over head cam, or in block cam.
No more 4 cyl

Ah, was not aware of that. I learned that the rear head is supposed to have different spark plugs than the front. Odd.

Lol. Ya. Look at the 2.3 mustangs and rangers of this same era. 8 plugs, and a shield that covers 4 so you nearly have to pull the head to get to them
