This is a good example of why it's import find Nissan's definition of the code:
P0447 - An improper voltage signal is sent to ECM through EVAP canister vent control valve.
It is not your gas cap.
It looks to be the canister vent control valve or wiring.
This is located in the charcoal canister at the back of the vehicle.
Find and use the FSM to troubleshoot. Most parts are easy to access.
Good luck!
