Your check engine light can be triggered by a multitude of signals from your OBDII system. You need to check what the code is. You can read it yourself by turning your key ON (do not start)-OFF-ON-OFF-ON on the third ON any codes should flash on the odometer window. Once you have the code, you can determine what the code is from OBDII.com, a web search, site search or just post what it is here. As mentioned above, if you cannot get it yourself Autozone will read it for free.
