What Causes the Yellow Steering System Warning Light to Illuminate?
1 Answers
Possible causes include a faulty power steering pump or blown fuse. Electric Power Steering System (abbreviated as EPS): This is a power steering system that directly relies on an electric motor to provide assist torque. Compared with traditional Hydraulic Power Steering (HPS) systems, EPS systems offer numerous advantages. The EPS system primarily consists of a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and Electronic Control Unit (ECU). Potential failure causes: Excessive air in the power steering system causing abnormal steering; foreign matter in the hydraulic steering lines leading to steering pump flow control valve sticking; loose connections in the power steering system resulting in steering fluid leakage; excessive wear of the steering gear piston cylinder, poor oil seal performance, or control valve adhesion/damage.
