Throttle failure. What are the symptoms?

When there is a problem with the throttle, the symptoms are: engine jitter, unstable idle speed, difficult ignition and high fuel consumption.

The key components of throttle valve include: throttle valve, electromagnetic driver, potentiometer, regulator and bypass valve.

Throttle failure can include two types: accessory failure and dirty throttle.

A, accessories failure problem:

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

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

In this case, you can replace the oxygen sensor and use better quality fuel.

Second, the throttle valve is too dirty:

Driving or driving habits in windy and dusty environments are basically the causes of dirty throttle. Too dirty throttle will lead to too low throttle opening, which will affect a series of problems.

In this case, you can use good engine oil, and at the same time, you should 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.

The explanation of the above throttle fault symptoms ends here. I hope Bian Xiao's introduction can help everyone. If you like it, praise Bian Xiao. This is the greatest support for Bian Xiao.
