The service engine light on a Chevy Venture is the same as that on many other vehicles. This light is located on the dashboard, and it indicates that there is a problem with the vehicle.
Two less serious reasons for the service engine light to come on are a loose gas cap or a wet engine. However, other potential causes are serious issues such as faulty spark plugs or a blown gasket. When it is lit, have a certified mechanic take a look at your vehicle as soon as possible. Driving while there is an issue with the vehicle could cause even more damage.
