Why did the Baojun 730 suddenly light up the fault light?
2 Answers
Baojun 730 suddenly lights up the fault light because the car has a fault. Carbon deposit issue: Poor gasoline quality can lead to incomplete combustion of the 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 incomplete combustion and the light coming on. Computer temperature correction issue: During cold starts, especially when the weather temperature drops sharply, the computer's temperature correction may cause the light to come on during startup. However, once the temperature drops to a certain level and stabilizes without fluctuations, the situation 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 values are incorrect or malfunctioning, it can lead to car body shaking and insufficient power.
The Baojun 730 suddenly lit up a warning light. I've driven many similar cars with this issue, and it's likely caused by several common problems. For example, an engine sensor malfunction, such as abnormal oxygen sensor signals, can trigger the warning light. Or, carbon buildup in the emission system may clog it, causing the computer to detect an anomaly and sound the alarm. Other possibilities include poor fuel supply, aging spark plugs, or even onboard computer software glitches leading to this situation. My advice is not to panic at first. Find a safe place to stop and check if any other warning lights are also illuminated on the dashboard—this can help determine whether the issue lies with the engine or another component. It’s best to drive to a 4S shop or repair center to use a diagnostic tool to read the trouble codes. Once the specific cause is identified, replace the faulty parts or clean the system promptly. Ignoring the issue for too long can lead to a sharp increase in fuel consumption and may even damage the engine internals, affecting driving safety. Regularly inspecting the car’s condition before driving and avoiding sudden acceleration to prevent part wear can help reduce such failures.
