Havent checked, but if I recall, that is a failed o2 heater.
Determining which sensor.......You definitely have at least 2, possibly 3 or 4....is the trick....
Any reputable shop can take care of this for you...it does not need to go to honda.
If you can, have it scanned again , and get the position......
sensor 1 is before the cat, sensor 2 is after. Replacing the sensor itself is a matter of unscrewing it and installing a new one, but you must check the heater circuit wiring on the proper sensor position before continuing.
