When the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Your car performs poorly and uses more fuel than it needs to.
It will run too rich or too lean changing from moment to moment.
A bad O2 sensor will cause the catalytic convertor to fail because the engine ran too rich and dumped too much rich exhaust into the cat - cats are very expensive, I just had a new one installed, sounded like it had rocks in it. And of course that assisted in the murder of the muffler. If the cat has failed, odds are that the O2 sensor has too.

What are symptoms of bad o2 sensor on 2006 f150?
I have experienced 3 major symptoms on a truck of this vintage with a 4.6 engine with a failing O2 sensor. 1. loss of power, about 10 % loss; 2. engine is slightly noisier, used to purr, now noisier, sort of a growl. 3. noticably increased fuel consumption (15-20%) at lower speeds (in town). Replacing the O2 sensor fixed all three symptoms . I made a fast trip, towing a boat (about 3 hours), and I think this may have contributed to the O2 sensor failure. Symptoms occured after this, and sensor completely failed (check engine light) several months later.
