P0445 has to do with the evaporative system and could be something as simple as a loose or leaking gas cap. Check that first. If the cap is good (new) and you still have the problem after clearing the code, there is a leak somewhere in the fuel system involving the filler tube, tank, filter or evaporative canister and sensors.
