a small evap leak is often interpreted as a loose gas cap , which it can be , it means the evap systems integrity has been breached , it can be an electrical solenoid , switch or just a vacuum line in the system . a bidirectional scanner can run the evap test after checking the gas cap , most well equipped shops can hook up a smoke machine to the evap system service port and run the smoke test , it there is a leak you will see the smoke , makes the diagnosis quickly . get an estimate from a reputable shop , by the way this problem has no effect on drivability , but should be fixed . cheers

SOURCE: code p0455 evap emission (large)
have the gas cap tested or just replace it, then disconnect the battery for 5 minutes to reset the code, then drive it for a few miles and see if problem comes back, if it does a trip to the dealer is in order, as this may be covered by your emission warranty which is good for 70,000 miles.

the code your getting is for the evaporator emissions system,look for any vacuum hose or hose that's coming from the canister tank,and check to see if its bad or has rotted and fell off,or is closed off,any one of those hoses will cause that to happen,it may just be one that got knocked loose by accident,check any hose that has to do with vacuum or the emission system,a sensor is what caused that code to show up,so it did its job,good luck on finding it,you,ll know the problem when you come to it.

Hose cracked,loose,different switches,sensors,gas cap, any number of things. It is a system, on to itself and not easy to repair.
