Understanding the Check Engine Light: Steady vs. Flashing

• A steady light generally means a minor issue, but you should schedule a diagnostic promptly to prevent further damage.

• A flashing light indicates a serious problem that could lead to severe engine damage. If this happens, pull over immediately and contact your local repair shop.

Common Reasons Your Check Engine Light May Turn On

Some frequent causes include:

• Oxygen Sensor Failure: This sensor measures oxygen levels in your exhaust. A faulty reading can lead to reduced fuel economy and higher emissions.

• Loose or Damaged Fuel Cap: Surprisingly common and simple to fix, a loose fuel cap can trigger the check engine light right after refueling.

• Catalytic Converter Issues: The catalytic converter transforms harmful gases into less harmful emissions. Excessive carbon build-up or engine problems can cause it to fail, something we specialize in repairing at Greer Automotive.

• Ignition Coil and Spark Plug Problems: Your ignition coil sends the electrical charge to your spark plugs. Failure in this system can cause misfires, poor performance, and higher emissions.

• Mass Airflow Sensor Malfunction: This sensor measures the amount of air entering your engine. A faulty MAF sensor can lead to rough idling, poor acceleration, and starting issues.

No matter the cause, the ASE-Certified technicians at Greer Automotive are equipped with advanced diagnostic tools to accurately pinpoint and fix the issue.
