If your check engine light comes on, you don’t need to automatically assume that your engine is nearing total disaster.

At Carpenter’s Tire & Auto LLC, our local mechanics provide expert computerized auto diagnostics in the greater Meadville, PA area. Then, we can flawlessly complete the necessary repairs. Here are five common reasons that the check engine light turns on.
The catalytic converter is crucial for reducing harmful emissions by converting pollutants into less harmful substances. A malfunctioning catalytic converter can result in decreased performance and increased emissions, prompting the check engine light to illuminate.
One of the most common culprits behind an illuminated check engine light is a malfunctioning oxygen sensor. These sensors monitor the amount of oxygen in the exhaust gasses, helping the engine control module adjust the air-fuel mixture. A faulty oxygen sensor can lead to rough idling and decreased acceleration.
It might sound a bit strange, but a loose or missing gas cap can trigger the check engine light. The gas cap seals the fuel system and prevents the escape of vapors. If it's not tightly secured, it can lead to an imbalance in the fuel system, triggering the warning light.
The mass airflow sensor measures the amount of air entering the engine and plays a crucial role in determining the correct fuel injection. When this sensor malfunctions, it can lead to a rich or lean air-fuel mixture, affecting engine performance and triggering the check engine light.
Issues within the ignition system, such as a failing spark plug or ignition coil, may result in an illuminated check engine light. Faulty spark plugs or ignition coils could lead to misfires.
