What does it mean when the engine yellow light on the dashboard is on?

[MilaLee]

The reasons for the engine yellow light on the dashboard being illuminated are: 1. The air filter is clogged, causing poor air intake; 2. Faulty spark plugs, ignition coils, or fuel pump in the engine, or blocked fuel lines leading to poor combustion of the air-fuel mixture; 3. Poor fuel quality, resulting in increased carbon deposits inside the engine cylinders; 4. Damaged, poor contact, or interrupted signals from sensors such as the water temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, or oxygen sensor. An engine is a machine that converts other forms of energy into mechanical energy, suitable for power generation devices, determining the vehicle's power, fuel efficiency, stability, and environmental performance. It includes internal combustion engines, external combustion engines, jet engines, and electric motors.
