How often does Peugeot 408 throttle have to be cleaned?

Peugeot 408 throttle valve should be cleaned once a year/kloc-0. Throttle is a controllable valve that controls air to enter the engine. There are two types: traditional cable throttle and electronic throttle. 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. This combustible mixture is connected with the air filter and the engine block. The traditional engine throttle control mechanism works through a cable or a pull rod, with one end connected to the throttle pedal and the other end connected to 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.
