more then likely it the vapor pressure valve in the canister...to test the evap system it involves a scan tool and pressure tester....so unless you can get a hold of one or both of these...there's no point of telling you how to test then....try checking your gas cap for damaged gasket and reset the ecu (pull efi fuse for 5 sec) do this firt,,,your lightshould come back on,cause i don't think that the problem,...but thats an easy test to start with...you never know ..you mit get lucky
