Oxygen sensors do eventually get poisoned no matter how well the car is
cared for, that's why they do eventually need to be replaced. Some sources
even recommend replacement every 60K miles, which to me is overkill.

A LAZY sensor--one that is still operating but does not fluctuate its
voltage as rapidly as it should--will not necessarily set an error code,
but will cause you to fail emissions. It will not necessarily even affect
your fuel mileage or drivability either.
