How much is the new Santana throttle?

The new Santana spends about 120 yuan on cleaning the throttle in the 4S shop, but it is much cheaper to buy the cleaning solution by itself. The price of a bottle of cleaning liquid is generally around 20 yuan. After the throttle is cleaned, there is no need for manual matching. The driving computer will learn matching by itself. Throttle is a controllable valve that controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. There are two kinds of throttle valves: traditional cable throttle valve and electronic throttle valve. The traditional engine throttle control mechanism is connected with the throttle pedal through one end of a pull wire (soft steel wire) or a pull rod, and the other end of the pull rod is connected with the throttle linkage plate. The electronic throttle mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, so as to adjust the intake air.
