What happened to the fault light of Datong v80 engine?

1. Carbon deposition at the air inlet and piston top will lead to poor atomization, resulting in insufficient combustion and ignition; 2. When the cold car starts, especially when the weather temperature drops sharply, the light will be insufficient because of the computer temperature correction problem. But as long as the temperature drops to a certain temperature and there is no fluctuation, the change will be relatively stable; 3. The engine mileage is too long, the working characteristics of the spark plug are weakened, and the fault light is on. It is recommended to go to the repair shop for inspection. There are many possible reasons for the failure light of Chase V80 engine, but this kind of failure can only be checked and solved in 4S shop or repair shop. Engine fault lights can be divided into the following three categories: 1. False fault, reporting fault code, but working normally. It may be that an operation is beyond the control of the computer, and the computer has fed back the fault code, so it can be ruled out first, and then it can be judged whether there is a jump fault code; 2. Minor fault, no obvious engine fault. According to the information detected by the computer, further inspection shows that there is indeed some kind of fault, which does not affect the normal driving and slightly collides. Need to find a solution in time, such as the failure of the intake pressure sensor; 3. A major fault can be felt by naked eyes and driving sense, which seriously affects the normal work of the engine and needs immediate maintenance. If the engine power is obviously insufficient, it is probably the problem of the oxygen sensor. It may be that the quality of fuel used by the vehicle is poor, the supply pressure of the main fuel pump in the vehicle fuel tank is insufficient, and the fuel rail or injector is blocked, which affects the poor fuel injection. It is recommended to find a professional to check and maintain. 20 18 SAIC Chase V80 is also equipped with SAIC's own Internet system, which has many useful functions, including smart car housekeeper, online interconnection, remote adjustment, voice recognition and many other functions.
