Chrysler Repair: 442 Code on a 2000 Dodge Grand Caravan, dodge grand caravan, grand caravan

Question
Please help me get started finding the cause of a 442 code that showed up just as I was going to get the car inspected. Unlike other cars I have owned, I never bought a service manual for it. The code is for a small evaporative emission system leak. Can you outline the steps to take in order of most to least likely? Should I punt and take it in or is likely to be expensive?  Thanks, D.S.

Answer
well a small leak is just that a small leak .020 inches big.
can check the lines and see if u find any cracked they would be rubber connecting to a metal line ora plastic line thats where they leak most of the time. Plus a small leak can also e a hard part issue like a LDP,evap purge sol things along that line. Do u live near Atlanta?
