That little glowing check engine light on your dashboard can be easy to ignore—until it’s too late. But what does it actually mean? In this post, we’ll break down the most common reasons your check engine light comes on, what to do when it happens, and when it’s time to bring your car in for a professional diagnostic.
1. Common Reasons for a Check Engine Light
• Loose or faulty gas cap – A simple but common issue that can affect fuel pressure.
• Oxygen sensor failure – Can cause poor fuel economy and engine performance.
• Bad spark plugs or ignition coils – May lead to rough idling or trouble starting.
• Catalytic converter issues – A costly repair if left unchecked.
• Mass airflow sensor failure – Impacts fuel efficiency and engine function.
2. What to Do When Your Check Engine Light Comes On
• Don’t panic—check your gas cap first.
• Pay attention to performance changes (rough idling, loss of power, etc.).
• If the light is flashing, pull over safely and get your car checked immediately.
• Schedule a diagnostic check with a trusted mechanic.
3. Why You Shouldn’t Ignore It
A check engine light might not always mean an immediate breakdown but ignoring it can lead to bigger (and more expensive) repairs. Catching issues early saves you time, money, and stress.
