1. Engine Misfire: A misfire occurs when one or more cylinders fail to properly combust fuel, leading to rough idling, reduced power, and increased emissions.
2. Oxygen Sensor Issues: The oxygen sensors monitor the amount of oxygen in the exhaust gas to ensure proper fuel-to-air mixture and efficient combustion. A faulty oxygen sensor can cause the engine light to illuminate.
3. Catalytic Converter Problems: The catalytic converter helps convert harmful pollutants in the exhaust gas into less harmful substances. A faulty or damaged catalytic converter can trigger the engine light.
4. Faulty Spark Plugs/Wires: Worn-out spark plugs or damaged spark plug wires can affect proper ignition and cause the engine light to come on.
5. Fuel Injector Issues: Faulty fuel injectors can cause improper fuel delivery, resulting in rough engine idle, decreased fuel efficiency, and the illumination of the engine light.
6. Transmission Problems: In some cases, transmission-related issues, such as low transmission fluid or a faulty transmission solenoid, can cause the engine light to come on.
It is important to address the engine light as soon as possible to diagnose and resolve the underlying issue. Leaving it unattended can lead to more significant problems and potentially costly repairs in the future. It's recommended to have your vehicle inspected by a qualified mechanic or visit a reputable auto repair facility to accurately diagnose the cause of the engine light illumination.
