The Check Engine light is on because there is a problem with the emissions system. Once you have the problem repaired the light will go off.
The check engine light means there is a problem with the emission systems on the vehicle. The service engine light means that a regular schedule service is needed. Most of the time this means you need an oil/filter change.
