Common Causes of Check Engine Light Illumination
Various factors can trigger the check engine light, including:
- Oxygen Sensor Failure: This sensor measures unburned oxygen in the exhaust system and, when faulty, can reduce fuel efficiency.
- Loose Fuel Cap: A simple issue that can affect the entire fuel system and its efficiency.
- Catalytic Converter Issues: Necessary for reducing harmful emissions, it can cause significant increases in emissions when malfunctioning.
- Mass Airflow Sensor Problems: Measuring air entering the engine, its failure can affect performance.
- Malfunctioning Spark Plugs: Essential for combustion, worn plugs and wires can cause the engine to misfire.
