There is a plug on the accelerator. What happened when the car stopped and the fan turned?

The reason why the fan keeps turning after the vehicle is turned off is that the engine temperature is too high after parking, and the driving computer will automatically calculate the speed and time of the fan. The higher the engine temperature, the longer the fan rotates, thus protecting the engine. The engine temperature has dropped and the fan is still running, which may be the reason for the virtual connection of the circuit. You can try unplugging the harness of the fan and cut off the power alone. The function of automobile fan is to improve the air speed passing through radiator core, increase the heat dissipation effect and accelerate the cooling of water. Fans used in automobile engines are divided into axial fans and centrifugal fans according to their structural principles, and mechanical fans and electric fans according to their driving methods.
