When the power steering system warning light illuminates, it may be due to faults in the steering system sensor, steering gear, or power steering pump. Below is a detailed introduction to the automotive power steering system: 1. Function: It utilizes motor-generated power to assist drivers in steering. This system directly provides steering assistance through an electric power motor, eliminating the need for components like hydraulic power steering oil pumps, hoses, hydraulic fluid, transmission belts, and engine-mounted pulleys required in hydraulic power steering systems, thereby saving energy and protecting the environment. 2. Composition: The automotive power steering system can improve vehicle stability by independently braking each wheel and participating in engine system management when instability trends are detected, ensuring driving safety. The system mainly consists of a speed sensor, reduction mechanism, torque sensor, motor, and electronic control unit.

What are the symptoms of a stuck throttle cable?

Introduction to the symptoms of a stuck throttle cable: 1. Throttle cable failure modes include sticking, breaking, wear, and damage, with sticking and breaking being the most common; 2. The throttle cable is too long: the curvature radius of the throttle cable path is too small, with too many turns, causing the cable to move poorly and stick; 3. The grease in the throttle cable's steel wire rope has dried up, increasing the pulling resistance: the throttle cable's dust cover has poor sealing, allowing dust, mud, and other debris to enter the protective tube, hindering the normal movement of the cable. Additional information: The main causes of throttle cable wear failure are improper fixation points, lack of fixation points, or detachment of fixation points, leading to friction between the throttle cable and other components; the breaking failure of the throttle cable is mainly related to its installation method, typically manifesting as bending fatigue before breaking.
