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.
