What Does the Check Engine Light Mean?

Last updated 2 years ago

Your car’s dashboard contains a number of lights that provide you with valuable information about the performance and condition of your vehicle. One of the most critical lights on your dashboard is the check engine light. When you notice that your check engine light has become illuminated, this light could indicate a number of automotive issues. When you notice that your check engine light is on, you should be sure to schedule a repair appointment for your car right away. Read on to learn more about what your check engine light may mean.

Loose Gas Cap

One of the common reasons for your check engine light to go on is a loose gas cap. If you fail to screw your gas cap all the way onto your vehicle after you refuel, your check engine light will provide you with a warning. If you tighten your gas cap and the light remains on, this is a sign that your car is in need of more serious repairs.

Bad Oxygen Sensor

A bad oxygen sensor is another possible reason why your check engine light may be on. The oxygen sensor is designed to monitor the oxygen levels in your exhaust system. With a bad oxygen sensor, the efficiency and overall performance of your engine may decline. Your mechanic can replace your oxygen sensor with a working component.

Broken Catalytic Converter

When your catalytic converter breaks, your check engine light will warn you by turning on. A broken catalytic converter can cause your engine to emit more harmful emissions from its tailpipe. To get the to bottom of your illuminated check engine light, you will need to visit your auto repair center.
