Common Reasons Why Your Check Engine Light is On
Below are just a few of the reasons your check engine light may have come on recently:
- Oxygen sensor failure – An O2 sensor or oxygen sensor calculates the amount of oxygen that’s left in a vehicle’s exhaust system. The sensor then sends this information to your car’s computer that regulates the amount of air and fuel mixture that should enter the cylinders. A bad oxygen sensor can impact other components like spark plugs and the catalytic converter.
- Catalytic converter problems – A catalytic converter is a vital part of your car’s exhaust system. It takes the carbon monoxide that’s generated by your vehicle and turns it into carbon dioxide. Catalytic converter replacement can be fairly expensive, so it’s best to attempt to prevent this type of repair by properly maintaining your vehicle.
- Loose gas cap – A simple cause for an illuminated check engine light could be a loose gas gap. A properly tightened gas cap ensures your car’s entire fuel system is under the proper pressure.
Bad spark plug wires – A spark plug wire transfers electricity from the engine coil to the spark plug itself. When these wires begin to fail, you may experience a decrease in engine performance, a rough idle, as well as lower gas mileage. - Spark plug and ignition coil problems – An ignition coil is what creates the electricity charge that spark plugs require to ignite the mixture of air and fuel in the cylinders. Older cars have just one ignition coil, but newer models typically have one per cylinder. If one of these coils malfunctions, your engine light will often come on. The same goes for faulty spark plugs as well.
