Common Causes for the Check Engine Light to Turn On

When your check engine light appears, it’s your vehicle’s way of letting you know something needs attention. While some issues are minor, others can quickly lead to costly repairs if ignored. Understanding the most common causes can help you respond quickly and keep your vehicle running safely and efficiently.

Some common causes for a check engine light include:

• Loose or faulty gas cap
• Failing oxygen (O2) sensor
• Malfunctioning Mass Airflow Sensor (MAF)
• Catalytic converter problems
• Ignition coil or spark plug issues
• Vacuum leaks
• EGR valve failure
• Faulty sensors or electrical issues

Ignoring a check engine light can lead to poor fuel economy, performance problems, and more serious mechanical failures over time. Prompt diagnostics help identify the issue early, protect your vehicle, and prevent more expensive repairs down the road.

What Does a Flashing Check Engine Light Mean?

A flashing check engine light is an urgent warning that your engine is experiencing a severe problem, most commonly an active misfire. When the light flashes instead of staying solid, it indicates that unburned fuel is entering the exhaust system, which can quickly damage critical components like the catalytic converter. This type of issue can escalate fast, so it should never be ignored or driven on for long.



If your check engine light is flashing, the safest action is to pull over as soon as possible and shut the engine off. Continuing to drive can lead to major engine damage, expensive repairs, and potential safety risks. A prompt diagnostic inspection will identify the source of the misfire or malfunction and help prevent further harm to your vehicle.
