What are the symptoms of throttle failure? How many kilometers does the throttle change?

What are the symptoms of throttle failure? Symptoms of throttle failure are: engine jitter, unstable idle speed, difficult ignition and increased fuel consumption.

The components of throttle valve mainly include: throttle valve, electromagnetic driver, potentiometer, controller and bypass valve.

There are two kinds of throttle faults: accessory faults and dirty throttle.

A, accessories failure:

Accessories failures mostly refer to the failure of throttle oxygen sensor, which is mostly caused by the use of inferior fuel, especially fuel mixed with sulfur.

However, this rarely happens. If yes, it is recommended to check the three-way catalyst at the same time.

In this case, the oxygen sensor can be replaced and better quality fuel can be used.

Second, the throttle is too dirty:

Driving in a windy and dusty environment or bad driving habits are all reasons for dirty throttle. Too dirty throttle will cause the throttle to open too low, which will lead to a series of problems.

In this case, you can use better quality engine oil, develop good driving habits, and pay attention to the maintenance of the throttle.

If you go to a 4S store, clean the throttle and adjust the throttle opening, the price ranges from 20 yuan to 200 yuan.

How many kilometers does the throttle change?

The accelerator has no fixed replacement mileage or service life. As long as the throttle is broken, it should be replaced.

Carbon deposits will appear on the back of the accelerator after long-term use, and riders can regularly clean the carbon deposits on the back of the accelerator.

Throttle is called the throat of the engine, which can control the amount of air entering the engine.

After we step on the accelerator pedal, we actually do not directly control the fuel injection quantity, but directly control the throttle opening.

After stepping on the accelerator pedal, the throttle opening will become larger, so the amount of air entering the engine will increase.

When ecu detects that the air quantity entering the engine increases, it will increase the fuel injection quantity, which will increase the engine speed and accelerate the car.

If there is serious carbon deposit on the accelerator, it will affect the idle speed of the engine.

When cleaning the throttle, remove the throttle, then clean it with professional cleaning agent and wipe it clean.

After cleaning, reinstall the throttle and the computer, otherwise the fuel consumption of the car will increase in a short time.

Ecu has a strong learning ability. After detecting the carbon deposit on the throttle, it will use another set of control logic to control the throttle.

If the cleaned carbon deposit does not match the computer, ecu will still use the control logic with carbon deposit to control the throttle valve without carbon deposit, which will lead to an increase in fuel consumption. (Photo/Text/Photo: Ask and Answer Animals) @20 19
