What Does It Mean When The Check Engine Light Turns On?

Whenever you turn on your car, there are certain dashboard indicators that might come on. One of these is the "check engine" light. If you notice this indicator, it's a warning sign that there might be something wrong with your car. It might be something minor or it might be an emergency. Regardless, you will want to have your car inspected by an auto repair technician. 

Why Your Car Has So Many Indicator Lights

Your car has an onboard diagnostic system that informs you of any problems that might exist with the car. If there is a problem with the powertrain, this can lead to your check engine light displaying.

A Check Engine Light Can Mean Anything

There are several inexpensive causes of a check engine light such as a defective gas cap. When a gas cap is faulty, it causes gas vapors to be released into the atmosphere and can cause the check engine light to turn on.

However, the check engine light could also be caused by an internal problem with your engine. Because each car is different, it can be impossible to determine what the cause of the check engine light is unless you take your car to an auto repair service.

Flashing Lights Can Indicate a Serious Problem

The check engine light might be solid or it could be flashing. If the check engine light is flashing, this is a sign that there is a more serious problem with your car. Some cars will have the check engine light become a different color if the situation is urgent.

When in doubt, you will always want to pull your car over to the side of the road and have it taken to a car repair service rather than driving it. In some cases, even continuing to drive it for a few minutes will cause irreversible damage. 

It Isn't Necessarily Your Engine

A check engine light will not necessarily mean that something is wrong with the engine. A problem with the transmission, sensors, or emission equipment can all contribute to the check engine light turning on.

Therefore, you will want to get to the bottom of what is causing your check engine light to turn on so you can fix it as soon as possible. Then, you'll be able to get your car back on the road and you won't have to worry about your car breaking down.
