this is an AF sensor code- calling it an o2 is ok but not the same troubleshoot
bank 2 is the front bank.

troubleshooting is detailed and requires a scanner, DVOM, wiring diagrams as well as component pin outs....
I cannot add that info.

This sensor must come from ACURA if it must be replaced.

The Honda air fuel ratio sensor is a bit different than a standard zirconium O2 sensor. If you have wiring diagram you can test the wiring to see if that is what is open. Go to AZ and buy a Haynes manual and I can help you with this. You'll need to post a picture of the circuit.
