When your vehicle’s check engine light illuminates, it may indicate a range of minor to potentially serious issues. From a loose gas cap to faulty spark plugs, it is important that you know what your vehicle’s dashboard is trying to tell you. Brothers Tire Sales of Kannapolis, NC, is here to let you know why you might see your check engine light. Continue reading for a guide from your local auto maintenance team.

4 Reasons Why Your Check Engine Light Illuminates

1. Loose Gas Cap

If your gas cap is loose, you may notice your check engine light come on. An improperly sealed gas cap will no longer regulate your fuel tank’s pressure. Repair or replace it to save fuel and reduce your carbon footprint.

2. Broken Oxygen Sensor

Your vehicle’s oxygen sensor is responsible for keeping track of unused oxygen in the exhaust system. As such, when this sensor malfunctions, you will most likely see your check engine light engage. Avoid damaging your catalytic converter or spark plugs by replacing it ASAP.

3. Spark Plugs Need Replacing

Spark plugs light up the combustion chamber, which activates the ignition. If they are broken or damaged, your check engine light will appear, which indicates possible ignition coil damage, a backed-up catalytic converter, or low engine performance. Have an auto maintenance crew replace your spark plugs to remedy these issues.

4. Catalytic Converter Fails

Your catalytic converter converts carbon monoxide to dioxide in an effort to protect human health as well as the environment. When it fails, your check engine light will illuminate as a way to let you know your vehicle is producing dangerous emissions. Change it out to prevent pollution and overheating.
