If your check engine light flashes on, it doesn’t necessarily mean that your engine is nearing complete failure. But you should still get to the shop for diagnostics so that the issue can be identified and resolved before it gets worse. At Chuck’s Auto Care, our local mechanics provide expert check engine light diagnostics and repair in the greater Barboursville, VA area. Here are five common problems that trigger the check engine light.

Faulty Oxygen Sensor

One of the leading causes of an illuminated check engine light is a malfunctioning oxygen sensor. Responsible for monitoring the amount of unburned oxygen in the exhaust system, a faulty sensor can lead to decreased gas mileage and worsening emissions. 

Failing Mass Airflow Sensor

The mass airflow sensor (MAF) measures the amount of air entering the engine, helping the engine control module adjust the fuel injection accordingly. A malfunctioning MAF sensor can lead to decreased fuel-efficiency and rough idling.

Faulty Catalytic Converter

The catalytic converter plays a vital role in reducing harmful emissions by converting pollutants into less harmful gasses. When this component fails, it can lead to a drop in performance and increased emissions, triggering the check engine light. 

Ignition System Issues

Problems within the ignition system, such as faulty spark plugs or ignition coils, can lead to misfires and trigger the check engine light. Regular tune-ups and prompt replacement of worn-out components can keep the ignition system in top shape.

Loose/Damaged Gas Cap

The gas cap seals the fuel system and helps maintain proper pressure. When it's loose or damaged, it can cause a drop in pressure, triggering the sensor. Thankfully, this is one of the simplest issues to address – just ensuring a tight seal can often make the light disappear.
