Here’s everything you need to know about the check engine light and how we can help.
What Does the Check Engine Light Mean?
The check engine light, often represented by an engine-shaped icon on your dashboard, illuminates when your vehicle’s onboard diagnostic system detects a problem related to emissions, engine performance, or other essential components. While the light itself doesn’t pinpoint the exact issue, it serves as an early warning system that requires immediate attention.
Common Causes of the Check Engine Light
- Loose or Faulty Gas Cap: A loose or damaged gas cap can cause a minor evaporative emissions leak, triggering the check engine light.
- Oxygen Sensor Malfunction: The oxygen sensor monitors the level of oxygen in the exhaust gases. A faulty sensor can affect fuel efficiency and emissions.
- Catalytic Converter Issues: A failing catalytic converter can cause the check engine light to illuminate and may indicate more significant engine problems.
- Spark Plug or Ignition Coil Problems: Issues with spark plugs or ignition coils can lead to engine misfires and trigger the check engine light.
- Mass Airflow Sensor Failure: The mass airflow sensor measures the amount of air entering the engine. Failure can affect engine performance and emissions.
- Battery or Charging System Problems: Low voltage or charging system issues can trigger the check engine light and affect electrical components.
What to Do When the Check Engine Light Comes On
- Check Gas Cap: Ensure the gas cap is tight and secure. If loose, tighten it and see if the light turns off after a few driving cycles.
- Note Symptoms: Pay attention to any unusual symptoms your vehicle may be experiencing, such as rough idling, reduced fuel efficiency, or unusual noises.
- Schedule Diagnosis: Schedule an appointment with The Auto Experts for a thorough diagnostic inspection. Our technicians use advanced diagnostic tools to retrieve trouble codes stored in your vehicle’s computer system.
Our Check Engine Light Diagnostic Process
At The Auto Experts, we follow a comprehensive diagnostic process to identify and address the cause of your check engine light:

- Component Testing: Based on the trouble codes and initial inspection findings, we conduct further testing of relevant components. This may include testing sensors, checking electrical connections, and performing system tests to pinpoint the root cause of the problem.
- Repair and Service: Once we identify the issue, we provide you with a detailed explanation of the problem and our recommended course of action. We only perform repairs with your approval and use quality parts to ensure lasting performance and reliability.
