Some vehicles have to have to light reset via the computer. Sorta like the Check Engine Light.

Go to any auto parts store have them clear it. If it comes back you probably have a small evap leak somewhere. These can come from anyplace on the evap system.

It may take a few (no more than 3) trips for the computer to reset. HTH. -Jim
