There is a fuse in the underhood PDC that supplies the heater circuits for both front and rear O2 sensors in parallel. If the fuse is out, it can affect the ability to get up to and maintain operating temp for the sensors, which can cause problems with staying in closed loop.

The PDC is the Power Distribution Center. It is the black plastic box next to the battery. The fuses are not labeled, just check them all. I am pretty sure that there is no O2 sensor fuse in the fuse box in the passenger foot well area.

Check your Owners Manual or Factory Service Manual for more info. If you don't have an OM or an FSM, you should get one, try eBay or the Junkyard.
