Cars need regular maintenance to continue functioning safely, and when problems arise, it is important for drivers to take action as soon as possible, regardless of how big or small the issues might be. One particular issue that crops up quite frequently is the check engine light. The Car Care Council indicates that one in 10 cars on the roads in the U.S. is operating with the check engine light on. When this symbol is illuminated on the dash panel, it is warning the driver that something is amiss underneath the hood.

"When the check engine light comes on, it means that a vehicle system, such as the ignition, fuel injection or emission control, is not operating properly, even if the vehicle appears to be running normally," said Rich White, the executive director of the Car Care Council. "A glowing check engine light doesn't mean you have to immediately pull the car to the side of the road, but it does mean you should get the car checked out as soon as possible."

Often, drivers dismiss the light, assuming it is on because there is a problem with the light itself. However, there are many different problems that could be related to the light, including a faulty oxygen sensor or ​trouble with the spark plugs. If the light starts blinking, it means the issue is more severe and requires immediate attention.

The sooner the light is addressed, the less severe the damage will likely be. Ignoring the light could lead to worsening issues and more expensive repairs.

In some cases the damages may not be worth the cost, as buying a new used car could be a better financial decision. Drivers can find a slew of makes and models at New Jersey State Auto Auction, and each vehicle is Carfax certified.
