The check engine light turns on to inform the driver that the computer has detected a 'fault' and that the driver should address the problem. If the light is on constantly, it's considered a "minor" fault but something that needs attention as soon as you get a chance. If the light is flashing it means that something serious has been detected and you need to deal with it NOW!
You can either take the vehicle to a shop and have the mechanic connect a code reader to your vehicle
OR
you can take your vehicle to your local auto parts retailer and borrow, rent or buy a code reader that will tell you what's wrong.
Whichever you decide, you won't be able to guess what's wrong, and nobody can help you unless and until you connect the vehicle to a code scanner.
Often it's something relatively simple even though it may be a bit expensive. Oxygen sensors for example can be pricey and you should replace both sides at the same time. On the other hand it can sometimes be as simple as a loose gas cap. The code scanner is a great help and if you intend to do much of your own work it's good to have your own scanner.
