What does the engine light on the car dashboard mean?

The engine light displayed on the car dashboard indicates an engine malfunction. Possible reasons include: 1. The need to replace the air flow sensor or oxygen sensor, spark plugs or ignition coils, or unclean engine cylinders with carbon deposits causing engine knocking; 2. Poor combustion state, low-quality fuel, etc. However, the specific cause needs to be diagnosed by reading the fault code with specialized equipment at an after-sales service center. The ways the engine light appears on the dashboard and solutions: 1. There are two ways the engine light can illuminate: yellow light or red light. If it's a red light, immediately go to a 4S shop for inspection and repair as the fault is severe; if it's a yellow light, the fault may not affect driving but should still be checked as soon as possible. 2. The car can read the fault code through the OBD interface using a computer. If you are interested in the vehicle's mechanical/electronic systems, you can purchase a Bluetooth module for the OBD interface to view and clear fault codes with a laptop or Android phone.
I've encountered the situation where the engine warning light on the car dashboard illuminates several times. The most common causes are issues with the engine system, such as dirty or failed sensors (like the oxygen sensor), or emission problems triggering the catalytic converter alert. Sometimes it's caused by aging ignition coils or spark plugs leading to cylinder misfires, or clogged fuel injectors resulting in incomplete combustion. I remember once during a long-distance drive, the light suddenly came on while the car was shaking violently. I immediately pulled over to check the engine oil and coolant temperature. Finding the oil level slightly low, I topped it up and the warning disappeared. But this was just a temporary fix - the real issue might be more serious, like a faulty catalytic converter or ECU error codes. My advice is never to delay when this happens. Take the car to a repair shop to scan for trouble codes with an OBD scanner to pinpoint the exact cause. Regular maintenance like cleaning intake pipes and replacing filters periodically can prevent such issues. Most importantly, never ignore the warning light - safety always comes first.
