most of the time it is because the gas cap isn't on tight. Make sure it is and sometimes the light will go out in an hour or so. The loose cap tells the computer that there is a vapor leak which causes the warning light to come on..My car repair man told me this and it did take care of the problem. Hope this helps..

seems that your vent hose on the tank is plugged so the tank is over pressurrizing sending the error code and not allowing you to fill it all the way unclog the vent tube and this will solve the problem
Graham Head
there is a vapour purge line from the tank to a charcoal cannister. The line& cannister has been contaminated with liquid gas. When the engine attempts a normal purge from cannister it gets loaded with raw gas, causing rough running and cherck engine light. Replace cannister. Never over fill gas tank, especially on hot sunny days
