Last May I had this problem and it cost 158.00 to have it fixed. Something with the gas cap and hose. Could this light come on for any other reason.
 
The check engine light can come on for multiple reasons. Basically, it tells you when there is a problem with one of the systems on your car. It is best to have the code read to determine which system is malfunctioning. Sounds like before you had a problem with the Evaporative Emissions system. This system could be the problem again or it could be another system. Good luck
 
Often when you fill up with gas, if you don't turn the cap until it clicks a few times, the light can come on. Tighten you cap and drive it a bit and see if the light goes off?
