Why does the Baojun 730 suddenly light up the malfunction indicator lamp?

[AmaraDella]

Baojun 730 suddenly lights up the malfunction indicator lamp because the car has a malfunction. Carbon deposit issue: Poor gasoline quality can lead to insufficient combustion of the air-fuel mixture in the cylinder, causing the light to come on, and it is also prone to carbon deposits. The presence of carbon deposits in the intake tract and piston top can result in poor atomization, leading to insufficient combustion and triggering the light. ECU temperature correction issue: During cold starts, especially when the weather temperature drops sharply, the malfunction indicator lamp may light up due to the ECU's temperature correction. However, once the temperature stabilizes at a certain level without fluctuations, it will become relatively stable. Abnormal fuel supply pressure: Abnormal fuel supply pressure and faults in the intake pressure sensor can cause this issue. If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect or malfunctioning, it can lead to car shaking and insufficient power.
