Hi all, i don't know much about Evap and all.

Just wondering what a evap prob could cause, i got a p1457 code
engine light come at least 1-2 time every 1-2 week.
Can i just clean the Evap ?, What could be a solution ?
does someone can explain me what does de Evap canister does
at the worse i'll just change it, just wanna see what you guys think about it

Thanks
