Nissan 370Z Forum - View Single Post - P2A00 Code after HFC install. Need some input

Update:
I haven't been driving the car very much since I switched the O2 sensors, but a couple days ago the code came back while the engine was idling. It's just that the code was "P2A03 - Powertrain" "O2 sensor circuit range/performance bank2 sensor1" and not P2A00 like before the switch.

Does this mean that the fault is most likely to be the postcat O2 sensor? Or am I missing something here?

EDIT

I ordered a new post cat o2 sensor, hoping this will fix it.

Do I just clear the code with the torque app after I've put the new one in?
