1st thing to do is check the connector & the wiring. Wouldn't hurt by spraying some electric cleaner on the body side of the connector (not on the o2 wiring side), clear the code and see if it comes back. If it does and you have checked the wiring continuity back to the DME then it's time for a new o2 sensor.
