When the car is driving, the engine emission fault light is on, the car accelerates and slowly steps on the accelerator. The car body shook slightly, but it felt weak. Just changed the oil, air filter and filter throttle valve. Hello! The engine fault light is on, but it does not affect normal driving. The reasons are as follows: automobile exhaust emission is not up to standard, which is mainly caused by excessive carbon deposition; The engine fault light may also be caused by the failure of internal parts of the engine system; The bright spot of the engine fault light may also be caused by the fault of the gearbox system.

The engine fault light is on, but it does not affect normal driving. The reasons are as follows: 1. Automobile exhaust emission is not up to standard, which is mainly caused by excessive carbon deposition. Of course, the failure of the three-way catalytic converter and the blockage of the fuel nozzle will also lead to the engine fault lights, and the main reason for these fault lights to light up is related to the oil quality and whether the gasoline is fully burned. So when we refuel the car, we should refuel according to the gasoline standard stipulated by the manufacturer. If it is 95 # gasoline, we will never add 95 # gasoline. Moreover, in order to reduce the occurrence of the above-mentioned fault lights, you should also regulate your driving behavior during normal driving, and you can't have illegal behaviors such as sudden braking and stepping on floor oil.

2. The engine failure light may also be caused by the failure of internal parts of the engine system. Anyone who knows the internal structure of the engine knows that its engine system is composed of many sensors and various small parts, which need to be maintained in the usual driving process. In addition, with the passage of time, these components and sensors are prone to failure. Therefore, if this happens, it is recommended to go to the 4S shop for maintenance instead of pulling out the key and restarting the vehicle to solve the problem of faulty lights. This method is unreliable and impractical. 3. The bright spot of the engine fault light may also be caused by the fault of the gearbox system. The internal structure of gearbox is also troublesome, which requires high technology to manufacture. It is difficult to develop its own gearbox like domestic independent brand cars. The internal parts of the gearbox are worn, and the error message of ABS failure, etc. Will make the engine fault light come on. But now many cars separate the engine fault light from the gearbox fault light.

If the engine fault light is always on after the car is started, pay attention to whether the water temperature, oil pressure and engine idle speed are normal. If they are normal, we can drive a short distance, but for the sake of the life of the car, we should check them in a 4S shop or a repair shop.
