check engine and warning lights are on
 

Hello fellow fj owners, i currently have a problem with my 2007 fj cruiser. Check engine light and 3 other lights turns on from time to time. I already had the error scanned and what appeaered are these errors p0441 and p0456. Already searched online and it appears that there is a vapor leak. I had all the hoses checked, canister, fuel pump, dropped the tank and found no problem. Also already changed the fuel cap. Can anyone of you shed light and give a solution to this problem of mine? Thanks! Have a good day!
