How to change the idle motor?

If the idle motor needs to be replaced, it must be replaced in the 4S shop or repair shop of the car, and it cannot be replaced without authorization, so as to avoid problems with the idle speed of the car and affect the driving safety.

The idle motor controls the opening of the bypass channel, thereby controlling the idle speed of the engine. Under normal circumstances, the idle motor can be scrapped with the vehicle and does not need to be replaced. However, if there is something wrong with the idle motor, the idle speed of the engine will be affected under various working conditions.

Idle motor is composed of stepping motor and worm gear reducer, and its function is to control the opening of bypass pipeline. According to the working condition of the engine, the opening of the idle motor will be adjusted. For example, when the air conditioner is idling, the opening of the bypass passage will be increased to ensure the engine idling and the normal function of the air conditioner.

Extended data:

The replacement of idle motor is introduced as follows:

Engine idle speed is mainly controlled by closed loop, that is, ECU opens the bypass pipe to a preset opening according to factors such as water temperature and whether the air conditioner is turned on. When the engine is no longer idling, the bypass passage will be closed and the engine speed will be controlled by the throttle opening.

The idle speed of automobile engine is rarely controlled by bypass, but directly by throttle. When idling, the throttle opens a small gap to meet the intake demand at idle speed.
