I just can’t stand driving with that light on. My experience is that I can replace the sensor, but that the ethanol messes it up again. I just reset and everything is fine. No change in performance or mileage, and I am NOT going to replace a catalytic converter for anything!
Two Honda Accords and a Ford F-150 doing the same thing is proof enough for me that ethanol is not good for an engine/system.

A piece of black electrical tape fixes it.
