Wuling Hong Guang S has a fault light indicating a throttle fault.

1, change gasoline. The poor quality of gasoline added to the car leads to insufficient combustion of gasoline, and the engine fault light is on, so it is necessary to replace the gasoline with good quality.

2. Repair the oxygen sensor. If the plug of the oxygen sensor is loose or the oxygen sensor is damaged, the mixture will be too thin or too rich, and the engine fault light will light up, so it is necessary to repair or replace the oxygen sensor.

3. Replace the spark plug. Carbon deposition in the spark plug leads to unstable idle speed and poor acceleration, and the engine fault light will light up, so the spark plug needs to be replaced.

4. Clean the three-way catalytic converter. If the three-way catalytic converter is blocked, the engine fault light will light up. When refueling, you can add a three-way catalyst cleaner to the fuel tank. When the vehicle is driving, the cleaner will clean the three-way catalyst.

5. Clean the fuel injector. The nozzle is blocked, resulting in poor fuel injection of the engine, and the engine fault light is on, so it is necessary to clean the nozzle.

6. Repair the throttle position sensor. The fault of the throttle position sensor causes the engine fault light to come on and needs maintenance.

7. Clean the throttle. The throttle valve is too dirty, resulting in too rich mixture, and the engine fault light is on, so the throttle valve needs to be cleaned.

8. Add engine oil. If there is too little oil, the oil fault light will light up to remind the driver to replenish the oil in time.

9. Repair tires. If the tire pressure is abnormal, the tire pressure fault light will light up. The driver needs to repair the tire. If the tire pressure is too low, you need to inflate it with a pump. If the tire pressure is too high, you need to deflate the tire.

10, repair the gearbox. If the gearbox fault light is on, it may be that the gearbox is short of oil or has other faults, so it is necessary to add gearbox oil or repair the gearbox.
