    if you're around 60,000 it might be a good idea to replace them..... otherwise, generally it's hard to tell if it's not reading correctly if you're not throwing an o2 CEL

    yes it deteriorates over time. supposedly replacing older o2 sensors will improve your gas milage.

    if one goes bad, you will know because it triggers the check engine light.
