Reasons Why Your Check Engine Light Might Be On
- Oxygen Sensor Failure: The oxygen sensor measures the amount of unburnt oxygen in the vehicle’s exhaust system. If not replaced, this can lead to reduced fuel efficiency and increased emissions.
- Loose Fuel Cap: Before causing panic, it’s always a good idea to check if the fuel cap is on properly. A loose cap can trigger the light because it affects the pressure within the fuel system.
- Catalytic Converter Failure: This part converts harmful carbon monoxide into carbon dioxide. A failure can reduce fuel efficiency and increase harmful emissions.
- Spark Plugs and Wires: Worn or fouled spark plugs, or failing plug wires, can cause the engine to misfire, reducing its performance and fuel efficiency.
- Mass Airflow Sensor Failure: This sensor measures the amount of air entering the engine to determine how much fuel is needed. A malfunction can decrease fuel efficiency.
- Ignition Coil Issues: Ignition coils help spark the spark plugs. A failure here can lead to an engine misfire.
- Exhaust Gas Recirculation (EGR) Valve Failure: The EGR system reduces pollution by recirculating exhaust back into the engine intake. A malfunctioning EGR valve can hinder performance and increase emissions.
- Software Updates: Sometimes the vehicle’s computer system just needs an update, and the check engine light is a way of indicating this.
