How Often Should a Car's Throttle Body Be Cleaned?

[OHaven]

Currently, there are no specific regulations on how often a car's throttle body should be cleaned. It is recommended to clean the throttle body approximately every 20,000 to 40,000 kilometers. The cleanliness of the throttle body is related to driving habits and environmental conditions, and it should be cleaned when it gets dirty. From a symptomatic perspective, when idle speed becomes unstable, cleaning should be considered. The throttle body is a controllable valve that regulates the amount of air entering the engine. There are two types: traditional cable-operated and electronic throttle bodies. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. In traditional engines, the throttle body's operating mechanism works via a cable or rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. Electronic throttle bodies primarily use a throttle position sensor to control the throttle's opening angle based on the engine's energy requirements, thereby regulating the amount of air intake.
