Why does the car make a humming sound when turning at low speed?

This situation occurs due to a malfunction in the power steering pump. The following is a detailed introduction to the car's power steering system: 1. Function: It uses the power generated by the motor to assist the driver in steering. The system directly provides steering assistance through an electric power machine, eliminating the need for a hydraulic power steering system's essential components such as the power steering oil pump, hoses, hydraulic oil, transmission belt, and pulley mounted on the engine, saving energy and protecting the environment. 2. Composition: The car's power steering system can improve stability when the vehicle shows unstable tendencies. The electronic power steering system can independently brake each wheel and participate in the engine system management to ensure driving safety. The car's power steering system mainly consists of a speed sensor, reduction mechanism, torque sensor, motor, and electronic control unit.
