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?

  1. 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.
  2. Oxygen Sensor Issues: A faulty O2 sensor always shows wrong fuel-air ratios, which greatly affects engine performance and emissions.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
