Well if that is the code you are getting when using a scan tool , it means there is a leak somewhere in the fuel/evap system. To actually pinpoint the leak, you would have to do a "smoke test" to see where the actual leak is taking place. That type of test really needs to be done by a mechanic that has the equipment to do it.
Trouble code P0442 means:Evaporative emission control system leak detected (Small leak)

P0457 Evaporative Emission Control System Leak DetectedIt means there is a vapor leak between the gas cap, tank, and engine.P0457 Evaporative Emission Control System Leak DetectedIt means there is a vapor leak between the gas cap, tank, and engine.
It is a vapor leak in the fuel system. Starting in 1996 vehicles check for leaks down to .020 inch.
It has a fuel system leak, can be fuel line, etc.( liquid leak) or (fuses) faulty gas cap/fuel emission system leak.
