What Does the Engine Light Mean on a Car?
Introduction
The engine light is one of the most common warning lights that can appear on your car’s dashboard. It can be a bit scary to see this light come on, but it’s important to remember that it’s just a warning. The engine light doesn’t mean that your car is going to break down right away. However, it does mean that you should take your car to a mechanic as soon as possible to have it checked out.
What Does the Engine Light Mean?
The engine light is designed to alert you to any problems with your car’s engine. These problems can range from minor issues, such as a loose gas cap, to more serious issues, such as a blown head gasket. In general, the engine light will come on when the car’s computer detects a problem that could affect the engine’s performance or emissions.
What Should I Do If the Engine Light Comes On?
If the engine light comes on, the first thing you should do is try to figure out what caused it. If you can safely pull over, do so and check the following:

If you can’t find anything wrong with the car, you should take it to a mechanic as soon as possible. The mechanic will be able to use a diagnostic tool to determine what caused the engine light to come on.
