1 Answers
Substandard gasoline quality and carbon deposits in areas such as the throttle valve and fuel injector can cause the light to come on when the emission system of the Shuai Ling engine fails. Substandard gasoline quality: Poor gasoline quality, such as misfiring in one cylinder, can lead to issues in the preheater, fuel supply system, ignition system, and three-way catalytic system, resulting in excessive exhaust emissions. At this point, the engine control computer records a fault code and illuminates the warning light. Carbon deposits in areas such as the throttle valve and fuel injector: Excessive carbon deposits in areas like the throttle valve and fuel injector can cause the fault light to come on. It is recommended to inspect and clean the carbon deposits inside the engine.
