What Does Engine Fault Mean?
2 Answers
Engine faults can be caused by failures in the fuel supply system, ignition system, intake system, exhaust system, or various sensor components. Below are specific reasons why the engine fault light may illuminate: 1. Exhaust Emissions Not Meeting Standards: Issues such as poor fuel quality, failure of the catalytic converter, excessive carbon buildup in the intake manifold, clogged fuel injectors, faulty oxygen sensors, or occasional engine misfires can trigger the engine fault light. Among these, poor fuel quality is the most common cause. 2. System Malfunction: The engine fault light may illuminate due to malfunctions in the engine system, such as faults or poor electrical connections in components like the throttle pedal sensor, throttle position sensor, mass airflow sensor, or crankshaft position sensor. 3. Transmission System Fault: In some vehicles, transmission system issues, including internal faults, slipping, or overheating, may also be indicated by the engine fault light.
Engine failure means there's a problem with your car's engine preventing it from functioning properly. It may manifest as difficulty starting, unexpected stalling, or insufficient power. As someone who enjoys studying cars, I've found common causes include: fuel supply issues like a damaged fuel pump or clogged filter leading to poor fuel delivery; ignition system faults such as spark plug carbon buildup or ignition coil leakage; malfunctioning sensors like oxygen sensors disrupting air-fuel ratio causing vibrations; or cooling system leaks leading to overheating shutdown. When the engine warning light comes on, you should be alert. Sudden engine failure during highway driving is particularly dangerous as it may cause loss of control. Remember to regularly check fluid levels to avoid accelerated wear from oil deficiency. If you notice abnormal noises or vibrations, pull over immediately and call for assistance - never push through, safety comes first. Simply put, it indicates failure within the engine or related systems, requiring prompt repair.
