Drive with Confidence

Your vehicle’s check engine light (CEL) is a critical warning system that alerts you to potential problems with your drivability, electrical, or emissions systems. Whether you drive a Ford, Chevy, or any other brand, this dashboard indicator is designed to notify you the moment an issue arises, often before any major symptoms are noticeable.

At Leon’s Auto Center in Keene, NH, we specialize in quick and accurate check engine light diagnostics to keep your vehicle safe, efficient, and running at its best.

Understanding the Check Engine Light: Steady vs. Flashing

When your check engine light illuminates:

• 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.

If you’re driving around Keene, NH, Dover, NH, Rochester, NH, Portsmouth, NH, Barrington, NH, or nearby, Leon’s Auto Center is your go-to destination for expert check engine light service in Strafford County.

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 Leon’s Auto Center.
• 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 technicians at Leon’s Auto Center are equipped with advanced diagnostic tools to accurately pinpoint and fix the issue.
