The weather conditions in winter are harsh, and the engine is more prone to problems. When the ignition is turned on, the engine fault light lights up on the dashboard, and it cannot be driven on the road. It is necessary to conduct a comprehensive inspection of the vehicle to avoid serious failures and cause major damage. loss.

Reasons why the engine fault light is on in winter

1. The combustion state of the engine is not good, and the temperature in winter will be relatively low, especially in the northern region. The outdoor temperature in the northern region can reach minus one to twenty degrees Celsius in winter. When the vehicle is cold started, the engine cannot immediately enter the optimal state. In the driving state, it is natural that the conditions required for fuel combustion cannot be achieved, so the engine fault light is turned on.

2. There are many carbon deposits in the engine cylinder, and the carbon in the carbon deposit has the characteristics of oil absorption. The temperature of the cylinder is difficult to reach a normal and stable temperature, and then the engine fault light is on.

3. The quality of the fuel is poor or the fuel is notbusinessFilling with the specified model, filling with low-grade fuel, the engine will be severely worn, and the engine fault light will come on. The fuel filled in the vehicle has a specified label, and the gasoline of the specified label needs to be filled, so that the engine will be in better condition and will not malfunction.

4. There are faults in the sensors in the engine system, such as the water temperature sensor and the oxygen sensor. The faults in the sensors will cause the data to be misjudged, which will cause the engine fault light to light up, and a comprehensive inspection and corresponding maintenance of the sensors is required.
