I just went through this last week. My car has 123K on it, original
O2 sensor. I think I have a few symptoms which may be due to it's
heading south, so I asked my mecahnic about testing it.

He'll test it, but wants to replace it for another reason: after about
100K or so, the things get brutally welded to the manifold, and sometimes
require major surgery to remove. I may ask him to bust it loose and
test it, or maybe just replace it anyway.
