OBDII Trouble Code

[firedog1]

I have a 2004 Tundra DC with 6900 miles on it. The Check Engine Light just came on and I ran a DTC check that came up with the code P0442 (Evaporative Emission Control System leak Detected - Small leak). Do I need to take it to a dealer to fix, or is it something that can I can do myself? I don't have a repair manual for this truck yet, So I don't know where to start. Any ideas on what to look for and where to start would be greatly appreciated.

Thanks

Probably just the gas cap not tight enough. Common error code. After a couple of starts and some driving it should clear.
