Q: Check engine light on 2002 Chevrolet Prizm

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have a 02 Prizm LSi 4AT with 124,000. Check engine light came up with this code P0446 (Evap Emission/Control System Vent/Circuit Malf), gas cap is new, new iridium spark plugs, air filter, gas treatment cleaner. Im afraid if i take it to a mechanic im gonna get ripped off. I wanna be clear of what items should be changed with this code P0446? Thanks.
