Hello I will help you with your question,
There are dozens of reasons the check engine light may be turned on. Some are serious and some are not too serious so you will need to have the codes read out so we get a diagnostic starting point.
As long as the engine seems to run normally and the light is not flashing it is safe to drive to your local chain autoparts store where they will read the codes at no cost. Post the codes you get back here and I can help you with the meaning and what needs to be done to keep the light off and make the computer happy.
Let me know what you get for codes and how I can help
