Hi:
It sounds like there is a problem with the O2 sensor. The only way to be sure is to have the sensor checked. It may be good and something may be wrong with the circuit. I wish I could be more confident and say replace the sensor, but it may not be the problem. The codes provided only point you in the direction of the problem.

Let me know if this helps.
