What is the cause of the automobile throttle failure?

With the development of technology and industry, there are more and more types and functions of cars. However, with the increase of service life and frequency, many failures will inevitably occur, among which the most common and dangerous is the throttle failure. Next, let's talk about what to do if the accelerator fails.

First, let's look at the cause of accelerator failure.

1. The gearbox is out of order.

With the use of automobile gearbox, there will be wear and tear, which will lead to the decline of automobile performance in the long run and eventually lead to the failure of various parts of the automobile, including the accelerator. If there is something wrong with the gearbox, one of the most direct manifestations of the fault is that the accelerator of the car can't be stepped on, and the engine speed will suddenly increase directly. This is because the engine is suddenly at zero load due to power failure, which will lead to its speed fluctuation. Generally, when this problem occurs, the fault light of the engine will light up, and we can judge by reading the fault with the diagnostic instrument.

There is something wrong with the throttle of the car.

Automobile throttle is an important part of automobile. Its main function is to control air to enter the engine and mix with gasoline to become combustible gas. Finally, it plays the role of combustion and work. It connects the air filter with the engine block, which is the engine throat of the car. In addition to controlling fuel injection, the throttle valve also controls air intake through the throttle valve. Therefore, once the throttle fails, it will also cause problems with the throttle of the car.

3. Automobile brake priority system.

At present, most cars are equipped with automobile brake priority system, which is a system that makes the brakes work first when the brake pedal and the accelerator pedal are pressed at the same time, but the accelerator does not respond. So when the accelerator fails, we can first check whether the car pad touches the brake, causing both pedals to be stepped down at the same time.

We all know the cause of accelerator failure. Next, let's talk about how to deal with the sudden failure of the throttle.

Once the throttle fails, the most important thing is not to panic Then make sure the car is in a safe area, and then check one by one according to the above reasons. If the owner himself is not familiar with the parts and operation of the car, he can ask other old drivers to check on his behalf, or go to a special repair shop for treatment.
