Is your check engine light (CEL) illuminated on your dashboard? Don’t panic!

At AAMCO Chicagoland, our team of expert technicians is here to help diagnose the issue and get you back on the road with confidence.
Why Does the Check Engine Light Come On?
The check engine light can illuminate for a variety of reasons, ranging from minor issues to more serious problems. Some common reasons why your check engine light might come on include:
Loose Gas Cap: Believe it or not, something as simple as a loose or damaged gas cap can trigger the check engine light. This is one of the most common reasons for a CEL, and it’s an easy fix.
Oxygen Sensor Malfunction: The oxygen sensor measures the amount of oxygen in your vehicle’s exhaust system and helps regulate fuel delivery. A malfunctioning oxygen sensor can cause the check engine light to come on and may result in reduced fuel economy and increased emissions.
Faulty Mass Airflow Sensor: The mass airflow sensor measures the amount of air entering the engine and helps ensure proper fuel delivery. A faulty mass airflow sensor can lead to engine performance issues and trigger the check engine light.
Catalytic Converter Issues: The catalytic converter is responsible for converting harmful emissions into less harmful gases. Problems with the catalytic converter, such as clogs or damage, can cause the check engine light to illuminate and may result in reduced engine performance.
Ignition System Problems: Issues with the ignition system, such as faulty spark plugs or ignition coils, can cause misfires and trigger the check engine light. Ignition system problems should be addressed promptly to prevent further damage to the engine.
