While an illuminated check engine light doesn’t automatically mean that disaster is near, it should still be addressed ASAP so that any emerging issues don’t get the chance to escalate. At Chuck’s Auto Care, we provide expert check engine light diagnostics and repair in the greater Barboursville, VA area. Here’s a look at five common reasons the check engine light comes on.

Catalytic Converter Issues

The catalytic converter reduces harmful emissions by converting pollutants into less harmful gases. When it starts to fail, your vehicle may experience reduced performance, poor fuel-efficiency, and increased emissions. 

Failing Oxygen Sensor

Oxygen sensors monitor the amount of unburned oxygen in the exhaust system and help regulate fuel-efficiency. Over time, these sensors can become dirty or fail altogether. A malfunctioning oxygen sensor can cause poor fuel-economy, increased emissions, and issues with the catalytic converter.

Malfunctioning Mass Airflow Sensor

The mass airflow sensor measures the amount of air entering the engine to determine the proper fuel-to-air ratio. If the sensor becomes dirty or fails, it can cause engine stalling, poor acceleration, and reduced fuel-efficiency. 

Loose or Damaged Gas Cap

A loose, cracked, or missing gas cap is one of the most common causes of a check engine light. The gas cap seals the fuel system and if it’s not properly secured, fuel may evaporate before it is directed toward your engine.

Spark Plug or Ignition Coil Problems

Spark plugs and ignition coils are essential for igniting the fuel-air mixture in your engine. Worn-out spark plugs or faulty ignition coils can cause engine misfires, reduced power, and poor fuel-economy. These components should be replaced as part of routine vehicle maintenance.
