    He didn't post which of the many O2 sensors it was, but it's most likely P0137, which CAN be caused by a cat issue, but is much more likely to be a sensor problem, especially when no other codes are present.

    P____?

    Post back when you can fill in that blank (should be four numbers). If you can't remember, get the code read again, and this time, write it down.
