What are the reasons for the engine warning light in Dongfeng Xiaokang vehicles?

[Espírito Santo]

Dongfeng Xiaokang engine warning light reasons: Poor combustion state: When the engine combustion state is poor, the engine warning light will illuminate. To ensure optimal working conditions and maintain normal service life, the engine is equipped with oxygen sensors to monitor combustion status. Poor combustion can increase fuel consumption and wear while also causing environmental pollution. Low-quality fuel: Automobile engines have specific fuel quality requirements, with increasingly stringent standards. Using substandard fuel will trigger the engine warning light. Carbon deposits in engine cylinders: As operating time accumulates, carbon deposits form inside the engine. These deposits can alter the engine's designed performance parameters.
