What is the reason why you can t speed up the car when you press the accelerator?

1. When stepping on the accelerator, the cable will drive the throttle, that is, the throttle, there is a position sensor on the throttle, and the control unit knows the opening of the throttle according to the throttle position sensor signal, and then calculates the corresponding signal voltage, and finally calculates the fuel injection amount of the vehicle according to the signal voltage. Therefore, if the throttle position sensor is too dirty or the voltage is out of balance, it will lead to the failure of the electronic throttle, and the throttle will not be able to go up at the end speed.

2. Eliminate the fault of the electronic throttle, then shift the attention to the three systems of the engine's air intake, oil circuit and ignition, the throttle position sensor signal, in fact, it is a member of the air intake system, the engine needs sufficient air to work normally, if the air intake system is leaking or blocked, then when the car fills the accelerator, there will be a drop in power, the speed can not go up, and the body shakes.

3. The oil circuit system of the engine is also important, if poor quality gasoline is added, it is likely to lead to gasoline pump burnout, three-way catalytic failure, piston failure, etc., which directly affects the engine power, and is easy to cause the engine to stall and accelerate to the vehicle speed.

Reasons and solutions for not being able to increase the speed of the car when pressing the accelerator:

1. If the throttle position sensor is too dirty or the voltage imbalance will lead to the failure of the electronic throttle, there will be a situation where the throttle cannot be stepped on to the bottom speed.

When stepping on the accelerator, the cable will drive the throttle, that is, the throttle, there is a position sensor on the throttle, and the control unit knows the opening of the throttle according to the throttle position sensor signal, and then calculates the corresponding signal voltage, and finally calculates the fuel injection amount of the vehicle according to this signal voltage. In the above situation, you need to check the gasoline pressure, cleanliness, and replace the gasoline filter element;

In the three systems of engine intake, oil circuit and ignition, the throttle position sensor signal is a member of the intake system, and the engine needs sufficient air to work properly.

This situation requires checking the ignition system, cylinder wire, spark plugs, etc.; Check the cylinder pressure, whether the engine is missing cylinders to work; Check whether the intake and exhaust lines are unobstructed (three-way catalytic blockage);

3. The oil circuit system of the engine is very important, if poor quality gasoline is added, it is very likely to cause the gasoline pump to burn out, three-way catalytic failure, piston failure, etc., which directly affects the engine power, and is easy to cause the engine to stall and accelerate without raising the speed. In this case, it is necessary to check whether there is a gasoline quality problem and replace the gasoline with better quality in time.

Precautions for car use:

1. Maintenance of automobile engine.

The engine of the car should be cleaned at the right time. Because long-term use will form a thick layer of carbon deposits on the surface of the engine, which will cause greater corrosion to the rubber parts in the engine.

Second, both gasoline and water should be protected from evaporation.

In summer, the temperature is generally high. So both gasoline and water evaporate more easily than usual. Because the water tank and fuel tank should be checked frequently, and when the gasoline and water are relatively small, they should be added in time.

3. Pay attention to hygiene inside the car.

Summer is the season when bacteria grow the fastest, so keep the interior of your car clean, especially car seat cushions, car steering wheel covers, and car floor mats that are prone to dirt.

Fourth, the car wiper should be replaced.

When driving in rainy days, you must pay attention to whether the wipers are good, the eraser leaves on the wipers for a long time will age, in order to drive in rainy days to have a better driving sight, the car wipers are best replaced once in one to two years.

Fifth, the car mat should be updated.

A good car mat is an important choice for car sun protection in the hot season. Choose a mat that is cool and not too slippery. In order to avoid traffic accidents caused by body sliding while driving.

Sixth, the car body should also be maintained.

Ultraviolet rays are also very harmful to the car, such as the penetration of the car paint. You may notice that after a long period of sunlight exposure to a white car, the color of the body becomes significantly lighter and yellower. Therefore, in summer, it is necessary to wax and glaze the car, which can play a role in protecting the car.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Can't afford to speed. Reasons:1The inside of the gearbox is slipping. 2.Three-way catalytic blockage. 3.The gasoline filter is clogged. 4.Failure of the oxygen sensor or air flow meter.

Summary. That is to say, after the accelerator is pressed, the engine speed rises slowly, and the power feels particularly weak, in this case, it is necessary to check specifically. Check this spark plug, there is also the need to check the ignition coil, there is also the need to clean the throttle and fuel injector to replace the spark plug, clean the three-way catalytic converter, and the pressure of the gasoline pump of the engine needs to be checked to see if it is normal, and it is also necessary to check the timing control and adjustment system of the engine.

These aspects need to be checked in detail, and they will all lead to a particularly weak engine power.

What's the deal with the car being powerless.

Summary. Hello dear<>

The answer you're looking for: Pressing the throttle doesn't increase your speed, which may be caused by the following reasons: The air filter is clogged:

If the air filter is clogged, it will lead to insufficient air flow, which will affect the combustion of fuel, which in turn will affect the acceleration performance of the vehicle. Clogged gasoline filter: If the gasoline filter is clogged, it will lead to poor oil flow, which in turn will affect the fuel of the engine** and affect the power performance of the vehicle.

Fuel pump failure: If the fuel pump fails, it will lead to a lack of fuel**, which in turn will affect the power performance of the vehicle. Air Flow Sensor Failure:

If the air flow sensor fails, the ECU (engine control unit) will not be able to accurately sense the air flow, which in turn will lead to a lack of fuel** and affect the acceleration performance of the vehicle. Ignition system failure: If the ignition system fails, it will lead to incomplete combustion, which in turn will affect the acceleration performance of the vehicle.

If you find that the acceleration performance of the vehicle is reduced, you can first check whether the above problems exist, and repair and replace them in time. If there is still a problem, it is recommended to go to a regular 4S shop or a professional car repair shop for comprehensive inspection and repair.

If the air flow sensor fails, the ECU (engine control unit) will not be able to accurately perceive the air flow, which will lead to insufficient fuel** and affect the acceleration performance of the Shenliang vehicle. Ignition system failure: If the ignition system fails, it will cause combustion to not swim and disturb the complete operation, which will affect the acceleration performance of the vehicle.

If you find that the acceleration performance of the vehicle is reduced, you can first check whether the above problems exist, and repair and replace them in time. If there is still a problem, it is recommended to go to a regular 4S shop or a professional car repair shop for comprehensive inspection and repair.
