What are the symptoms when the throttle is broken?

Basically, we all know that a car is assembled from one part to another, and each part is very important. The more parts, the more problems. If something goes wrong in the same part of our body, there will be specific symptoms. Today, Bian Xiao Automobile Company will tell our friends about the symptoms of cutting off the throttle. Let's take a look at them together.

Symptoms and treatment of throttle valve rupture: solution

The current repair method is to replace the throttle valve. I think the best way to repair the throttle is to replace the throttle motor. The throttle valve is broken, as long as a new motor is used, it can work normally. This not only saves resources, but also reduces expenses. Here is a brief introduction to how to replace the idle motor with Volkswagen's throttle.

From the appearance, it seems that you can't take it out without destroying the motor. I don't think so. We can easily find a breakthrough. Prepare some corresponding tools, remove the bolts of the rear cover, take out the rear cover, remove the two bolts of the throttle terminal, slightly pull out the terminal and erect it slightly. After careful observation, you will find a small hole next to the terminal, which is actually the positioning shaft hole of the transition gear shaft between the throttle idle motor and the throttle idle potentiometer. What needs to be done now is to punch out the gear shaft with this small hole, which is convenient for taking out the gear. Find a screwdriver with higher hardness, grind it to the corresponding size, and punch out the gear shaft, so that the intermediate gear can be removed. The next step is to take out the circuit board covering the motor, but half of the circuit board is blocked by the gear of the throttle idle potentiometer, so it is impossible to take out the whole circuit board. Cut it off only at the position shown in the figure, and then gently pry the circuit board along the edge space gap above the idling motor with a small screwdriver. Open the circuit board next to it. Unscrew the locating plate screw on the motor and take out the locating plate, then the motor can be taken out. Do some cleaning, prepare a new motor and replace it in the reverse order of disassembly. That's it. Change it.

Obvious symptoms and treatment of throttle rupture: symptoms

When the throttle position sensor fails, it will affect the abnormal idle speed of the engine (such as too high or too low idle speed, unstable idle speed and easy flameout) or abnormal acceleration of the engine (such as engine jitter and slow acceleration response). ).), sometimes it will affect the intermittent jitter and vibration of the engine when it is rotating.

What is an automobile accelerator? Throttle is a controllable valve to regulate the air entering the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and then it will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. So it is necessary to clean the throttle valve regularly. What are the symptoms when the throttle is broken? The car editor briefly introduced so much to his friends.
