Hello,

Best thing to do when the engine light gets illuminated is have the vehicle scanned for trouble codes. As this can be a number of reasons why it is on.
It could be something to do with the engine management system. It can also be exhaust and emission system faults as well.

Here is a helpful video on check engine light:

Please let me know of any questions.
Thank you.
