Hi .

This is not as bad as you may think so you can calm down a bit .

If its only the heater circuit then the O2 sensor may still be working when at its pre determine temp .

First check the wiring and connections on the O2 sensor if they look good then just have the O2 sensor replaced ,if your cat has over 80.000 miles then this is normal and i would think about replacing the front sensors .

You can still drive your car with out any great problem until you have time to take care of this little issue .

Then if needed please get back to me with the reply button, and not the poor or bad service, this way i can get back to you or suggest another expert if needed.
