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

[DeGavin]

When the engine yellow light on the car dashboard is on, it indicates the engine fault warning light. The reasons for it lighting up are: 1. The car's air filter is clogged, causing poor air intake; 2. Faulty spark plugs, ignition coils, fuel pump, or blocked fuel lines leading to poor combustion of the engine's air-fuel mixture; 3. Improper maintenance increasing the engine's operational burden. The solutions for the engine yellow light being on are: 1. Promptly check the condition of the car's engine; 2. Inspect the status of the car's sensors, air flow sensor, and spark plug components; 3. Check for any engine knocking; 4. Examine the ignition coils for faults; 5. Clean the engine carbon deposits.
