Hello Jcslmia, There is a very good article in the RepairPal Encyclopedia about the OBD II Code P0455. It means "Evaporative System Malfunction, Gross Leak". Follow this link to learn more about it; http://repairpal.com/OBD-II-Code-P0455 -
Answer 2
The exact problem is: there is a large leak in the EVAP system. It could be a simple thing as a missing or non sealing fuel filler cap, but for the rest you need a repair shop to test (possible smoke test) the EVAP system. Zee -
