Check Engine Light 101: A Beginner’s Guide to Car Trouble

Is your check engine light on? Don’t panic! The check engine light is a common issue that can be caused by a variety of factors, ranging from minor to major problems. In this article, we’ll cover the basics of the check engine light, what it means, and how to diagnose and fix the issue.

What is the Check Engine Light?

The check engine light, also known as the Malfunction Indicator Lamp (MIL), is a warning light on your car’s dashboard that illuminates when the onboard computer, also known as the Engine Control Unit (ECU), detects a problem with the engine or emissions system. The light can be steady or flashing, depending on the severity of the issue.

Why is My Check Engine Light On?

There are many reasons why your check engine light may be on, including:

• Loose or faulty gas cap
• Faulty oxygen sensor
• Catalytic converter problem
• Mass airflow sensor issue
• Ignition system problem
• Fuel system issue
• Emissions system problem

What to Do When the Check Engine Light Comes On

If your check engine light comes on, don’t ignore it! Here are the steps to take:

1. Check your gas cap: Make sure the gas cap is tightened properly. A loose gas cap can trigger the check engine light.
2. Check your dashboard: Look for other warning lights or messages on your dashboard. If the light is flashing, it may indicate a more serious problem.
3. Use a code reader: A code reader can help you diagnose the issue by retrieving the trouble code from the ECU. You can purchase a code reader or take your car to a mechanic.
4. Consult a mechanic: If you’re not sure what the issue is or how to fix it, consult a mechanic. They can help you diagnose and repair the problem.
