What Does the Check Engine Light Mean?
The check engine light is part of your vehicle’s onboard diagnostic system (OBD-II) and is designed to alert you when the engine or emissions system detects a problem. It can indicate a range of issues, from minor concerns like a loose gas cap to more serious problems such as engine misfires, sensor failures, or transmission troubles. A glowing or flashing check engine light is your vehicle’s way of saying something needs attention.
Common Reasons Your Check Engine Light Is On
At John’s Automotive Care, we’ve seen a wide range of issues that can trigger a check engine light, including:
- Faulty oxygen sensor
- Loose or damaged gas cap
- Bad catalytic converter
- Mass airflow sensor issues
- Spark plug or ignition coil failure
- Exhaust leaks or emissions system issues
- Transmission or engine malfunctions
- Vacuum leaks
Our technicians perform a thorough diagnostic scan to determine the root cause and provide a clear explanation of the problem before starting any repairs.
Why Prompt Diagnosis Matters?
Ignoring the check engine light can lead to poor fuel economy, reduced performance, or even permanent engine damage. Timely diagnosis not only protects your engine but also saves you money by catching small issues before they become major repairs. If your check engine light is flashing, it’s especially important to stop driving and have your vehicle inspected immediately, as this indicates a serious issue requiring urgent attention.
