What should I do if the engine warning light of Wuling Rongguang is on?

If the engine warning light is on, you can follow these steps: First, check whether the engine is running normally and whether there are problems such as shaking or black smoke. If so, try not to start the engine again. It is particularly important to note that you must not start the engine if the red light is on. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, press the start button once, or without pressing the clutch, turn the car key halfway to the 'on' position. After the car is powered on, the self-check function will be activated. Wait for 5-10 seconds and observe whether the warning light on the dashboard goes off. If the warning light does not go off, please go to a service station as soon as possible to find out the cause. The service station can use a portable diagnostic device to read the fault code, obtain fault information, and carry out targeted repairs. There are mainly 7 reasons why the engine warning light is on: Sensor failure: The sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, have poor contact, or the signal is interrupted, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to come on. Fuel quality issues: If fuel and engine oil are not added as required by the manufacturer, it may cause engine wear and lead to the warning light coming on. Poor combustion of the mixture: Poor combustion of the mixture can cause engine carbon deposits or knocking. After being detected by the oxygen sensor and reported to the ECU, the warning light will come on as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockage can all cause poor combustion of the engine mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine warning light to come on. The most common is turbocharger damage, accompanied by symptoms such as oil leakage, high oil consumption, reduced power, metal noise, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the car's intake, it may cause engine pipeline blockage, and in severe cases, the engine warning light will come on. If the air filter is not clean and not regularly cleaned, it can lead to intake problems. Exhaust issues: Exhaust faults can also cause the engine warning light to come on. The rear oxygen sensor, three-way catalytic converter, exhaust camshaft, and bearing faults are all causes of exhaust problems, with the three-way catalytic converter being the most common. Using leaded gasoline, lead or silicon-containing lubricant additives, impact damage to the three-way catalytic converter, and engine fuel supply system faults can easily cause three-way catalytic converter failure. Anti-theft system failure: If the car's electronic anti-theft system malfunctions, or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can also cause the engine to malfunction and the warning light to come on.
I usually drive to and from work, and have been driving a Wuling Rongguang for over ten years. The other day, the engine light came on while I was on the highway, which made me nervous. I immediately slowed down, turned on the hazard lights, and pulled over. After turning off the engine, I tried restarting it, but the light was still flashing yellow—probably a sensor issue or a clogged fuel line. I did a quick check under the hood: made sure the engine oil and coolant levels were adequate, as low levels can trigger warnings. I also checked the dashboard for other warning lights, like the brake or oil pressure light, which would require immediate attention. Safety first—don’t rush to keep driving! I then used my phone’s GPS to find the nearest repair shop or 4S dealership for a check-up. It turned out to be a minor sensor fault, and replacing it fixed the issue. Ignoring it could have led to costly engine damage, so I always advise friends not to delay when a warning light comes on—either do a quick check yourself or get it professionally inspected right away.
