When the “Service Engine” light (or “Check Engine” light) comes on, it can indicate various issues. Here are some common reasons:
- Loose or Damaged Gas Cap: A loose or damaged gas cap can trigger the light. Make sure it’s secure and in good condition.
- Oxygen Sensor Issues: A faulty oxygen sensor can affect fuel efficiency and emissions.
- Catalytic Converter Problems: Issues with the catalytic converter can lead to poor performance and increased emissions.
- Mass Airflow Sensor Issues: A malfunctioning mass airflow sensor can affect engine performance and fuel economy.
- Spark Plug or Ignition Coil Problems: Worn spark plugs or ignition coils can cause misfires and trigger the light.
- Exhaust System Leaks: Leaks in the exhaust system can lead to increased emissions and may activate the light.
- Battery or Charging System Issues: Problems with the battery or alternator can sometimes cause the light to illuminate.
- Transmission Issues: Some transmission problems can also trigger the service engine light.
It’s best to have your vehicle checked by a mechanic or use an OBD-II scanner to diagnose the specific issue. Ignoring the light can lead to more significant problems down the road.
