What Does The Check Engine Light Mean?

Meaning of the Check Engine Light

The check engine light, commonly a yellow, orange, or red engine icon, alerts you to an issue as soon as it arises. It’s meant to be visible, whether in the middle of your dashboard or off to the side. Unlike the oil light, which only indicates oil-related concerns, the check engine light might indicate various problems with your engine or emissions system.

If you notice this light, it means your car needs professional care. In the following section, we’ll look into what might be going on under the hood. And remember, when this light turns on, don’t go alone! We’re here to help, so bring your car in for a checkup.

Possible Issues that may trigger the Check Engine Light

Below are the possible issues that can cause the check engine light to come on

• Spark plug problem: As the name implies, spark plugs are electric sparks that ignite the air-fuel mixture required to propel your car. Spark plugs can wear out or accumulate carbon over time, and while these faults may be challenging to identify on your own, the check engine light makes it simple. When an issue develops, this light appears and alerts you quickly.
• Loose or faulty gas caps: Did you know that your gas cap does more than just keep fuel from leaking and maintain pressure? It also protects your fuel system by keeping impurities away from crucial areas. However, it’s easy to leave the cap loose mistakenly after refilling, and it might crack or wear down due to harsh weather conditions. When this happens, the check engine light reminds you that your gas cap may require attention.
• Failing catalytic converter: Like the liver detoxifies harmful substances in your bloodstream; this converter reduces toxic pollutants by turning them into less harmful gasses such as water vapor or carbon dioxide. However, road debris may crack or damage the converter when driving, and oil and coolant leaks can taint it, reducing its efficiency. When this occurs, the check engine light will illuminate, warning that it is time to repair the problem.

What to do when you see the Check Engine Light

The check engine light is designed to identify even minor problems in your engine. Ignoring it when it lights up can turn minor issues into huge problems or result in costly repairs down the road. So, as soon as you see that light, don’t hesitate to see a professional for an extensive check-up and the repairs your vehicle needs.
