Detailed explanation of Dongfeng Fengguang 580 warning lights includes: 1. Sensors: Sensors include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine warning light. 2. Engine: Poor engine maintenance is the most common cause of the engine warning light illuminating. Vehicles have specific maintenance schedules. If the owner fails to adhere to the maintenance intervals and combines this with poor driving habits, it will increase the operational burden on the engine. 3. Fuel and Oil Quality: Fuel and oil quality includes both gasoline and engine oil. The fuel added to a car usually has a specific grade. Manufacturers typically recommend which grade of fuel and type of oil to use. If the owner does not follow these recommendations, the system will eventually trigger a warning. 4. Poor Combustion: Faulty spark plugs, ignition coil issues, fuel pump failure, or clogged fuel lines can all cause poor combustion of the air-fuel mixture in the engine. Poor combustion leads to engine carbon buildup or knocking problems, which are eventually detected by the engine's oxygen sensor. Once reported to the ECU, the warning light will illuminate as an alert.
