Default Engine Code P0456?

Vehicle: 2006 PT Cruiser, base model

My check engine light came on last night; I followed the sticky here on how to retrieve codes and it gave me P0456, however it was not in the list of error codes on the forum. What does that code mean?

so i googled it and found another post here that says its the EVAP SYSTEM SMALL LEAK -- so what does that mean and how can I get it fixed? and do I need to take it to a Chrysler dealer or just any mechanic? and anyone know how much it costs?

There's a good chance that the last time you bought gas, you didn't click the gas cap on tight enough (at least 3 clicks). You can tighten it now and wait to see if the fault light goes out or tighten it and take the negative battery cable off for about 5 minutes. That will get rid of the light and reset the computer. If the light comes back on again, it could be a bad gas cap or a small leak (vacuum line someplace but try the easy way first.
