Hi there,

The P0446 code is for the vent control solenoid. This is bolted to the charcoal canister under the car. It's very common for these to fail. You can pull it off and add a power and a ground wire to see if the valve actually moves, but in most cases just removing it and looking inside will tell you if it's rusted up or not.
