Does the Chevrolet Cheng Jing throttle need to be changed for 200,000 kilometers?

The accelerator has no fixed replacement mileage or service life. Only when the throttle valve is damaged, it needs to be replaced, but the throttle valve needs to be cleaned regularly. Usually, clean the throttle every 20,000 to 40,000 kilometers. 15000 km can be cleaned once if you often drive on roads with extremely poor road conditions.

Throttle is a controllable valve that controls air to enter the engine. After the air 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: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works through a cable (soft steel wire) or a pull rod, one end of which is connected with the throttle pedal and the other end is connected with the throttle linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.
