2006 Toyota Avalon: OBD-II error P0441 and P0455

This answer was rated:

OBD-II error P0441 and P0455 on 2006 Toyota Avalon. What is wrong and what do I need to do to fix? Thanks.
Hello and thank you for using just answer!
These are evap related, was any work done to the car before this issue appeared?
Customer: replied 6 years ago.
No work has ever really been done, other than oil changes.
A few things here.
First replace the fuel capo with a factory brabd cap.
Disconnect the battery and retest. One of these codes can be related but may be a seperate issue with a loose hose or a bad valve for the evap system.
