The engine fault light comes on in cold weather.

? The reasons why the air-cooled engine fault light is on are as follows:

1, in the cold winter, the engine combustion state of the car is not good, in this case, when starting the car, the engine can't immediately enter a good driving state, so it can't meet the conditions of gasoline combustion, which will lead to the engine fault light.

2. It may be that the temperature is low, the battery is in poor condition and the supply is not timely. After the vehicle is warmed up, the engine fault light will naturally go out.

3. There may be something wrong with the sensor. When the sensor is damaged, the sensor is in poor contact or the sensor can't receive the signal, the engine can't get accurate instructions. In this case, the engine fault light will also light up.

4. If the owner does not add the corresponding type of fuel according to the needs of the car, it will affect the engine and cause the engine fault light to light up.

How to maintain cars in winter?

1. Replace or add antifreeze in time. The outdoor temperature is very low in winter. If the vehicle wants to run normally, it must have enough antifreeze, otherwise the water tank will freeze and the vehicle will break down. The antifreeze should be between MAX and MIX, and it should be replenished in time if it is missing.

2. Change the glass water in advance. When cleaning the front windshield with glass water in winter, be sure to use good quality glass water to avoid freezing when cleaning the glass. Otherwise, it will damage the wiper and affect the driver's sight.

3. Check whether the engine oil is sufficient. In winter, the car runs normally, and engine oil plays an important role. Before winter comes, be sure to carefully check whether the fuel gauge is within the normal range. See if your car needs an oil change. You can change the oil according to the mileage in the maintenance manual.

If it snows heavily, the car will be covered with thick snow. When cleaning the snow on the front windshield, be careful not to scratch the glass with sharp tools, especially the wiper. Do not open it before thawing, otherwise it will damage the wiper.
