Is it normal for the engine light to come on when the key is turned but go off after starting?

[MacParker]

It is normal for the engine light to come on when the key is turned but go off after starting. Reasons for the engine light coming on: Poor gasoline quality leading to incomplete combustion in the cylinder, resulting in carbon deposits; carbon deposits in the intake tract and piston top causing poor atomization and incomplete combustion; excessive mileage of the engine weakening the working characteristics of the spark plugs; faulty ignition coils causing poor ignition and incomplete combustion; aging machinery in older vehicles leading to poor engine performance and incomplete combustion. Function of the engine: The engine is the device that provides power to the car, determining its power, fuel efficiency, stability, and environmental friendliness. Types of engines include diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.
