One thing you can check is the rubber seal on the gas cap and the part of the metal tank filler it seals against and be sure that both are clean. I've lubed mine with vaseline when the SES light came on.
Think back to when the light originally turned on. Was it when the car was slightly warmed up and you restarted the car? Was the tank between 1/4 and 3/4 full? That'* when the car run a pressure check on the evap system. On mine within 30 seconds of starting after driving 3-4 miles, stopping for coffee at a gas station, and restarting the light came on. Both times I redid the gas cap and let the motor cool to that inbetween temperature, restarted at home, and it turned the light off.
