Reasons for the electronic power steering system indicator light being on: 1. There is excessive air in the power steering system, causing abnormal steering; 2. Foreign objects in the steering hydraulic line 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 sealing of the oil seal, or control valve sticking or damage. Solutions for power steering system issues: 1. Inspect the steering gear, steering pump control valve, oil cup filter, steering fluid, and clean the entire power steering system; 2. Check tire pressure and refill if necessary; 3. Inspect all connection points of the oil lines and tighten all connecting bolts; 4. Replace the oil line, power steering pump, or power steering gear.
What does it mean when the electronic power steering system warning light comes on? As a veteran driver with over a decade of experience, I've encountered similar issues many times. This light indicates a problem with the electronic steering system. Common causes include failure of the steering angle sensor due to dust accumulation or short circuits; control module malfunctions may also trigger false system alerts; unstable battery voltage, especially during startup in older vehicles, can activate the warning light. Once illuminated, the power assist system deactivates, making the steering wheel abnormally heavy and extremely difficult to turn, which poses serious risks of losing control in crowded urban traffic or during highway lane changes. I recommend immediately finding a safe place to pull over, checking for loose battery connections, and attempting to restart the vehicle. If the light remains on, a comprehensive diagnosis at a professional repair shop is mandatory. During routine maintenance, pay special attention to the steering system—regularly clean sensors to prevent worsening issues. Road safety must never be neglected, as this directly affects both your life and others' on the road.
