What should I do if the fan doesn't turn after Civic cleans the throttle?

Go to the repair shop to check and deal with it.

The reasons why the fan does not work after cleaning the throttle valve are as follows: First, the idle valve is too dirty and the cleaning is not thorough. Second, it may be that there are too many cleaning agents left in the cleaning process and they are not completely burned. Third, the throttle body is not well sealed. Fourth, computer data matching has not been re-executed. It is recommended to go to the repair shop for inspection and handling.

Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable-pulling type and electronic throttle type. 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. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle.
