If it was just the gas cap and the problem is now fixed, the code should clear evetually, or try a longer battery disconnnect...at least 10 minutes IIRC.
EDIT for better info. The MIL (check engine light) will turn off after 3 consecutive trips in which the system passes the evap test.
The history of the code will disappear after 40 consecutive warm-up cycles without a malfunction.
