The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

What could cause Service Engine Soon light to come on in 2003 Buick Regal?
Not sure which light you are referring to. The Service Engine soon light can be nothing more than a light reminding you to change your oil. It can also be what is normally called the Check Engine Light which means there is a problem with the emissions system. The cause can be as simple as a loose gas cap, and as complicated as a defective sensor. A scan of the ECU with an OBD2 scan tool will give you a fault code. This code will help determine exactly what part is defective. Turn on the ignition and see if you have a Check Engine light. It will only stay on for a few seconds. If you do, then this Service Engine Soon light means to perform regular maintenance. If not, it means the emissions system needs service.
