After slamming on the accelerator, the engine fault light came on. What happened?

1, carbon deposition at the air inlet and the top of the piston will lead to poor atomization, resulting in insufficient combustion and light on;

2. When the cold car starts, especially when the weather temperature drops sharply, due to the computer temperature correction problem, the light will be insufficient, but as long as the temperature does not fluctuate after falling to a certain temperature, the change will be relatively stable;

3. If the engine mileage is too long, the working characteristics of the spark plug will be weakened and the fault light will be on. It is recommended to go to the repair shop for inspection.
