What Causes the Engine Warning Light to Illuminate in the Baojun 510?
2 Answers
The reasons for the engine warning light illuminating in the Baojun 510 are: 1. Poor gasoline quality leading to incomplete combustion of the air-fuel mixture in the cylinder, resulting in carbon deposits; 2. Excessive mileage causing the spark plugs to weaken in performance; 3. Aging of vehicle mechanical components; 4. Damage, poor contact, or signal interruption in the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, or oxygen sensor. The solutions for the engine warning light illuminating are: 1. Promptly inspect the condition of the car's engine; 2. Check the status of the car's sensors, air flow sensor, and spark plug components; 3. Examine the vehicle for any knocking conditions; 4. Inspect the ignition coils for faults.
My Baojun 510 has been running for over three years, and there are several common reasons for the malfunction indicator light (MIL) to come on. A faulty or dirty oxygen sensor can trigger the emission超标灯亮；aged spark plugs failing to ignite properly reduce engine efficiency and may also activate the light. Additionally, a clogged catalytic converter or fuel system issues like blocked fuel injectors can cause the MIL to illuminate. When my light came on previously, the car started shaking, and fuel consumption increased—later diagnosed as an intake manifold leak due to deteriorated sealing rings. My advice: don’t delay upon seeing the light; use an OBD scanner to read fault codes for precise issue identification before heading to a repair shop. Safety first—prolonged driving with minor issues may damage engine components, leading to costlier repairs. Regular maintenance, such as cleaning the air filter, helps minimize dust intake and prevents such faults.
