Well it could be as simple as a new gas cap, or clean seal on it & tighten again. There are a few other items in the system too, but one common one is the vapor canister gets plugged up with dust & dirt.

SOURCE: O2 sensor and EVAP issues
P0446 is Aux Emission Control

The Evap Canister is located in the fender well, if I am not mistaken and the B1S2 is the O2 sensor is the second O2 sensor on the left side of the engine if your looking at it from the front of the motor.
