What Causes the Power Steering System Warning Light to Illuminate?

[LaLane]

Reasons for the power steering system warning light illumination: 1. Excessive air in the power steering system, causing abnormal vehicle steering; 2. Foreign objects in the steering hydraulic lines leading to jamming of the steering pump flow control valve; 3. Loose connections in the power steering system resulting in steering fluid leakage; 4. Excessive wear of the steering gear piston cylinder, poor oil seal sealing, or control valve sticking/damage. The steering system is a series of devices used to change or maintain the vehicle's driving or reversing direction, functioning to control the vehicle's direction according to the driver's intention. Steering systems are categorized into mechanical steering systems and power steering systems.
