What happened to the idle motor?

Hello, when the idle motor of the vehicle damages the engine, the following phenomena will appear: First, the internal circuit of the idle motor is broken. At this time, the performance of the engine is that there is no idle speed, and the engine will stall if it cannot operate normally. It is difficult to start the vehicle when it is started, so it is necessary to step on the accelerator pedal to start the engine. Second, the idle motor is stuck in the normally open position, even if the engine computer sends a signal to the idle motor, the motor cannot operate normally. At this time, the performance of the engine is that the speed is too high to be reduced, the speed is not controlled by the throttle, and the vehicle cannot run normally. Thirdly, the idle motor is in the off position. At this time, the performance of the vehicle is also that there is no idle speed, the engine is not easy to start, and you can stop by stepping on the accelerator. Fourthly, the circuit of the idle motor is faulty, and the plug is virtually connected, which makes the idle speed unstable and the vehicle feels like driving. The above points are all manifestations of idle motor failure. In addition, I would like to add that at present, the idle motors of many vehicles are integrated with the throttle, that is, the throttle assembly. The engine computer controls the throttle motor to realize the idle running of the engine. The fault performance is basically the same as that of the split idle motor, but the inspection method is slightly different. I hope my answer can help you!
