P0455 ...gross leak / no flow... need help

Hi to all....

Well, here I am again asking for help to troubleshoot this code.... p0455... I read that is related to the evap system... but don't know where to start checking....

any idea or any guess that what is the problem..? or where can I start checking?

I have erased the code and appears again after 2 or less days... so it has to be something that is bad or in bad shape...

thanks for all your comments and help....regards...
