What is the high idle speed after cleaning the throttle?

The phenomenon that the idle speed of the car becomes higher after the throttle is cleaned may be because the throttle is not set, and it needs to be set after the throttle is cleaned, otherwise the idle speed of the car will rise and fall. Throttle position sensor, also known as throttle opening sensor, is usually used to detect the engine state, and judge whether the engine is in idle working state or compound working state through detection. The throttle position sensor is a constant variable resistor installed on the throttle. When the throttle valve is in the idle position, the idle contact is closed and the idle working state signal is output to the computer. When the throttle is in other positions, the idle contact is opened, and the computer can identify the engine load through the signal sent by the throttle position sensor, so as to modify the fuel injection quantity of the engine and control the gasoline.
