Just happened a couple minutes ago. I already planned on taking it to the exhaust shop Monday. But is this code specific or just the whole system?

Well I'm having it checked out as I type this so fingers crossed its nothing serious

 

Chances are its just an O2 sensor.

 

Save yourself some money pal, go to the dealer and buy a new sensor. Better yet, call the dealer and get the part # for the Bank 2 sensor 2 and order it online from wholesalepartsguy or acurapartswharehouse or whatever you choose and install yourself. Piece of cake! DONE! Im a mechanic, so you can trust me, never had a sensor not fix that code. The sensor gets crud built up in it like burnt oil/exhaust and everything else coming out of your motor and clogs it up. Easy fix. one wrench and a connector.

 

lol... If only that line worked at my shop we would never have to argue with the customers. I do agree it needs a sensor. As the sensor gets older it cant change voltage fast enough in relation to the changing oxygen content and the computer sets a code for slow response. You can trust me , I am a honda master technician FYI: bank 1 is in the back of the engine, sensor 2 is on the bottom, just after the cat. converter.
