What does 'Please Service Power Steering' mean?
1 Answers
Please Service Power Steering indicates a power steering system malfunction. The causes of power steering failure include: 1. Excessive air in the power steering system; 2. Foreign objects in the steering hydraulic lines causing the steering pump flow control valve to stick; 3. Loose connections in the power steering system leading to steering fluid leakage; 4. Excessive wear of the steering gear piston cylinder, poor oil seal performance, or control valve sticking/damage. Power steering systems are classified into mechanical hydraulic power steering, electro-hydraulic power steering, and electric power steering. The principle of mechanical hydraulic power steering involves converting part of the engine's power output into hydraulic pump pressure to provide auxiliary force to the steering system, enabling tire rotation.
