P0449 is a fault with the vent control solenoid and not canister.
P0445 could be a resultant of P0449. Here is how you replace the vent control solenoid. Also inspect the vacuum feed tube O rings they may need to be replaced. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
