What Does the Check Engine Light Mean?

When your check engine light turns on, it means your car’s onboard computer has detected an issue. While some problems are minor, others can lead to serious damage if left unchecked. Common causes include:

• Faulty oxygen sensor – A failing O2 sensor can reduce fuel efficiency and increase emissions.
• Loose or damaged gas cap – A simple but often overlooked issue that can trigger the light.
• Malfunctioning catalytic converter – Essential for reducing harmful emissions, a faulty catalytic converter affects performance.
• Ignition coil or spark plug failure – Can cause misfiring and poor acceleration.
• Mass airflow sensor problems – Impacts fuel economy and engine performance.
• Transmission issues – Certain transmission problems can activate the check engine light.

Ignoring these warning signs can lead to costly repairs. It’s best to get a professional diagnosis as soon as possible.
