What are the reasons for the fault light on Wuling Rongguang Mini Truck?
2 Answers
Engine fault light usually indicates the following reasons: 1. Combustion: Poor combustion state. 2. Engine: Engine knocking. 3. Fuel: Poor fuel quality. 4. Engine cylinder: Dirty engine cylinder interior with accumulated carbon deposits. More related information is as follows: Self-check function: The engine has a self-check function to detect some faults on the car engine, mainly including faults of sensors and actuators. When a fault is detected, the computer will store this fault in the form of a fault code and will light up the fault indicator to remind the driver to take corresponding measures.
I've been repairing cars for 20 years, and the cause of the Wuling Rongguang Mini Truck's warning light coming on can vary widely. The most common issue is sensor malfunctions, such as an oxygen sensor failure causing excessive emissions, which triggers the dashboard warning light; or low oil pressure due to an aging oil pump failing to supply sufficient oil, easily activating the light. There are also cooling system problems, like excessively high water temperature or a non-working fan, where the ECU (that computer control module) detects abnormalities and immediately lights the warning. Don't delay—this could affect the engine's lifespan. I recommend owners first check the OBD diagnostic port for fault codes. Simple codes can be handled yourself, but for complex ones, it's best to visit a professional shop. Regular maintenance, such as changing the oil and cleaning sensor connectors, can help keep the warning light off.
