What does the engine light on the dashboard mean?
2 Answers
The engine light displayed on the dashboard indicates a fault in the engine (exhaust system). If it turns off a few seconds after starting the engine, it is a normal system self-check. If the light remains on, there may be a fault in the exhaust system. If the light flashes, it indicates engine misfiring, which can damage the catalytic converter. Possible causes for the engine (exhaust system) fault light to illuminate include: 1. Poor fuel quality, spark plug carbon buildup, faulty oxygen sensor, engine knocking, damaged coolant temperature sensor, or engine misfiring. 2. If not addressed promptly, it may lead to engine damage and non-compliant exhaust emissions. Notes: 1. If the engine (exhaust system) fault light is on but the coolant temperature gauge and oil pressure warning light are not activated, the vehicle can still be driven. However, drive cautiously at a reduced speed and seek the nearest auto repair shop for inspection. 2. If the coolant temperature is too high or the oil pressure warning light is also on, and you clearly feel the vehicle malfunctioning, pull over immediately and request assistance.
While driving, I noticed the engine icon on the dashboard lit up, which made my heart skip a beat. This indicates an engine issue, possibly due to a failed sensor, clogged fuel line, or ignition system malfunction. It's actually an electronic warning system reporting an abnormality that shouldn't be ignored, as it could damage core engine components. After pulling over to check and finding no strange smells or noises, I drove slowly to the repair shop. The mechanic connected a diagnostic tool and found it was an oxygen sensor alert; replacing it cost a few hundred yuan and fixed the issue. Preventive measures include regularly changing the air filter and engine oil to ensure smooth vehicle operation. Remember, though small, this symbol carries significant meaning—delaying repairs can lead to much higher costs, and safe driving should always come first.
