Your vehicle’s dashboard has several small indicator symbols that will light up to let you know when something is wrong with the car. Some are specific, like the light that indicates it’s time for an oil change. However, the check engine light is harder to interpret. The symbol is shaped like an engine and is sometimes accompanied by the words “check” or “check engine.” When it lights up, there are several possible problems that could require auto repair.

A Guide to Your Car’s Check Engine Light

What Does the Light Indicate?

The check engine light is connected to your car’s computer, which is linked with sensors throughout the vehicle. Whenever any of these sensors detects an issue, the computer stores a code indicating what the problem is, and the light will illuminate on your dashboard.

Common issues range from a loose gas cap to a malfunctioning catalytic converter or damaged fuel injector. The most common codes indicate that the ignition coils, spark plugs, and oxygen sensors may need attention or replacement. A blinking or red check engine light indicates a more severe problem, like a misfire that could cause major engine damage if you keep driving.

What Should You Do If It’s Illuminated?

If you notice your check engine light is blinking or red, pull over and call for roadside assistance. Immediately stopping the car can prevent serious damage to your engine, minimizing the cost of auto repairs.

If the light stays steady instead of blinking and is yellow, orange, or amber-colored, you should be able to continue driving for a short while. Take the car to an auto repair technician, who will use a code reader to determine what error code your car’s computer has produced. This will tell them which part of the car is damaged and what repairs are needed.
