I may not know much about Hondas, but that exact code on my car means the passenger side o2 sensor isnt responding correctly. If your car is setup the same way as mine, bank 0 is the driver side, and bank 1 is the passenger side, and thats the side with the bad o2 sensor. If you want to test it, swap your driver and passenger side o2 sensors and see if the code switches to bank 0 being bad.
