While the check engine light can be triggered by something relatively minor, it can also indicate a serious issue that affects your vehicle’s performance, efficiency, or reliability. At Auto-Lab Complete Car Care Center, we provide expert check engine light diagnostics and repair in the greater Plymouth, MI area. Here are four common check engine light triggers that should be addressed ASAP.

Faulty Oxygen Sensor

The oxygen sensor monitors the amount of unburned oxygen in your vehicle’s exhaust and helps regulate the air-to-fuel mixture. When it fails, the engine may run less efficiently, leading to poor fuel-economy and increased emissions. A bad oxygen sensor is one of the most frequent causes of a check engine light and should be addressed promptly to prevent damage to the catalytic converter.

Failing Catalytic Converter

The catalytic converter reduces harmful emissions by converting exhaust gases into less harmful substances. When it begins to fail, you may notice reduced performance, poor acceleration, or a sulfur-like smell. 

Worn Spark Plugs or Ignition Coils

Spark plugs and ignition coils are essential for proper combustion. When they wear out or malfunction, the engine may misfire, run rough, or struggle to start. These issues can trigger the check engine light and, if left unaddressed, may cause further issues.

Mass Airflow Sensor Problems

The mass airflow sensor measures the amount of air entering the engine to ensure the correct fuel mixture. If it becomes dirty or fails, the engine may hesitate, stall, or experience reduced power. A malfunctioning mass airflow sensor often causes the check engine light to come on and can negatively impact fuel-economy and drivability.
