What Should I Do if My Check Engine Light is On?
As drivers, we've all experienced that sinking feeling when the check engine light illuminates on the dashboard. While it might be tempting to ignore it, understanding what it means and knowing how to respond can save you from potential headaches and costly repairs. At Beer's Automotive Services & Repair in Shelby, OH, we're here to guide you through the steps you should take when your check engine light comes on.

Understanding the Check Engine Light
The check engine light is part of your vehicle's onboard diagnostics system (OBD). When it lights up, it's signaling that the car's computer has detected an issue. The problems can range from minor to serious, affecting the vehicle's emissions, performance, or safety.
Common Reasons for the Check Engine Light
- Loose or Faulty Gas Cap: One of the simplest issues is a loose or damaged gas cap. This can cause fuel vapors to leak, leading to decreased fuel efficiency and increased emissions.
- Oxygen Sensor Failure: Your car's oxygen sensor monitors the amount of unburned oxygen in the exhaust. A faulty sensor can affect engine performance and lead to higher emissions.
- Catalytic Converter Issues: The catalytic converter helps reduce harmful emissions. Problems with this component can result in poor engine performance and increased pollution.
- Spark Plug or Ignition Coil Problems: Spark plugs and ignition coils are essential for engine combustion. Issues here can lead to misfires and decreased fuel efficiency.
- Mass Airflow Sensor Failure: This sensor measures the amount of air entering the engine, helping to determine the correct fuel-air mixture. A faulty sensor can affect performance and emissions.
Steps to Take When the Check Engine Light Comes On
- Check for Serious Issues: If the check engine light is flashing, it indicates a severe problem, such as an engine misfire. In this case, reduce your speed, avoid heavy loads, and seek professional help immediately. At Beer's Automotive Services & Repair in Shelby, OH, we offer emergency diagnostics to keep you safe.
- Tighten the Gas Cap: A loose gas cap is an easy fix. Tighten it, and see if the light goes off after a few drives. If it doesn't, there might be a more significant issue.
- Reduce Speed and Load: If the light is steady, reduce your speed and avoid towing or heavy loads. This can help prevent further damage while you make an appointment for a check-up.
- Consult Your Vehicle’s Manual: Your owner's manual can provide specific guidance related to your vehicle's make and model. Follow any recommended steps before seeking professional help.
- Schedule a Diagnostic Test: To accurately diagnose the issue, bring your car to Beer's Automotive Services & Repair. Our team uses advanced diagnostic tools to pinpoint the problem and recommend the best course of action.
