The Service engine Soon light indicates an engine related problem, and the Service Vehicle Soon light indicates a problem with a system of the vehicle (usually a module or a sensor). The SES and the SVS lights are not set to come on at set intervals. They indicate that the computer has detected a reading for a sensor or module that is out of spec from where it should be. So either there is a problem, or sometimes, the computer just thinks there is a problem. Either way, the light's should not be ignored. Go to either AutoZone or AdvanceAuto and have them read your codes. It's free, and will help you diagnose / solve the problem.
