IT COULD ALSO BE YOUR CATALYTIC CONVERTER BECAUSE I HAD THE SAME PROBLEM

We had our check engine light come on and stay on. We took it to our mechanic who has a machine that reads codes. You need to find out what the problem is relating to the diagnostic code and then you can find out what kind of repairs you are looking at. Our code turned out to be an O2 sensor that he said would do no harm to the car at all other than slightly affect our gas mileage. If the check engine light comes on and flashes on and off you need to go directly to a mechanic as this is a more serious problem.

Tips for a great answer:
The MIL turns OFF after the engine is started if a diagnostic fault is not present.
The MIL remains illuminated after the engine is started if the control module detects a fault. A diagnostic trouble code (DTC) is stored any time the control module illuminates the MIL due to an emissions related fault. The MIL turns OFF after three consecutive ignition cycles in which a Test Passed has been reported for the diagnostic test that originally caused the MIL to illuminate.
The MIL flashes if the control module detects a misfire condition which could damage the catalytic converter.
When the MIL is illuminated and the engine stalls, the MIL will remain illuminated as long as the ignition is ON.
When the MIL is not illuminated and the engine stalls, the MIL will not illuminate until the ignition is cycled OFF and then ON.
