Why does service engine light come on?
The service engine light, commonly referred to as the check engine light, is one of the important indicators on a vehicle's dashboard. If it lights up, it means the Engine Control Unit (also known as the ECU) has detected a fault in the engine or any of its dependencies. So, why does service engine light come on?
- Loose or Faulty Gas Cap: A gas cap that is loose or damaged reduces fuel pressure within the system, which results in the ignition light showing.
- Oxygen Sensor Issues: A faulty O2 sensor always shows wrong fuel-air ratios, which greatly affects engine performance and emissions.
- Catalytic Converter Problems: If the catalytic converter is unable to perform its function, the vehicle will have difficulty changing the harmful effluents to non-harmful gaseous.
- Mass Air Flow Sensor Issues: The MAF sensor is the engine component that senses the return airflow, which may greatly affect the quantity of fuel injected, helping to enhance the engine's performance.
- Spark Plug or Ignition Coil Issues: Problems caused by faulty spark plugs and coils lead to misfiring, which results in a scattering of the engine, hence the light coming up.
- Issues with Transmission: On certain occasions, it may also be necessary to check the transmission, as this may cause the service engine light to illuminate.
- Low Oil Pressure Trouble or Excessive Engine Temperature Trouble: The engine warning light may also alert drivers that the engine is at risk, even when low oil pressure or an overheating condition exists.
