Your service engine soon light could indicate there is a minor problem with your vehicle’s electronic system or its engine. Some car manufacturers use this light, instead of a check engine light, to differentiate when there are minor issues with a vehicle. Some causes include a loose gas cap, low fluid levels, or problems with exhaust or emissions. The service engine soon indicator could also mean it’s time for your car to have a scheduled service like an oil change. You’ll want to get your vehicle to a certified mechanic or repair shop if your light appears. A shop technician can use an onboard diagnostic (OBD) scanner to find out exactly what’s wrong with your car and reset the service engine soon light.
