Why does the engine yellow light come on?

[AshleyFitz]

The reasons for the engine yellow light coming on are: 1. Sensor failure; 2. Fuel supply system failure; 3. Ignition system failure; 4. Intake and exhaust system failure. Precautions for daily use of the engine include: 1. Use clean fuel, as excessive impurities in the fuel can cause wear to the electric fuel pump; 2. Refuel promptly to ensure the engine's electric fuel pump provides sufficient fuel and stable working pressure for the injection system; 3. Do not disconnect electrical equipment circuits when turning on the ignition switch; 4. Regularly clean the fuel system and intake system. A dirty fuel system can lead to a series of issues such as blocked fuel lines, valves not sealing properly, poor fuel atomization, insufficient fuel supply, and low fuel pressure, all of which directly affect the engine's normal operation.
