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?
