I got my $$$ on the o2 sensor

Fuel trim is adjusted based on O2 feedback. The question is, is the O2 sensor really bad or is it seeing a a/f mix so out of whack from some other sub-system, that you get this code? O2 sensors have a service interval in the 75-90k range and shorten with rich conditions.
