Yea that's a pretty common one. Might not actually be the O2 sensor heater, because when anything goes wrong with one of the O2s, any of those codes could go. A new O2 would probably fix things, but you could go down to a Honda/Acura dealer, and ask them to read the code themselves, see if they can narrow it down actually to the heater.
Is the car acting weird? Rich/lean? Smoking?
