What are the causes of power steering failure in the MG GS?
4 Answers
MG GS power steering failure causes: Power steering pump failure: Lack of oil, obstructed oil circuit, air in the oil circuit. Pressure relief, solenoid valve not energized: Torque sensor failure and other forms of power assistance failure. Poor connector contact: Poor contact in the control system wiring harness connector, blown fuse, system fuse blown, relay damage, controller, motor or sensor failure affecting the electric power steering system. Power steering troubleshooting methods are as follows: Correct selection of hydraulic oil: Choosing the right hydraulic oil is key to ensuring the pump's efficiency and extending its lifespan. Regularly check the oil reservoir: Regularly inspect the oil level in the reservoir and replenish with clean hydraulic oil if insufficient. The filter element in the reservoir should be cleaned with alcohol during maintenance.
I've encountered the MG GS's power steering failure several times. The steering wheel suddenly becomes heavy, which is quite dangerous. The main causes are faults in the steering system components: for example, insufficient steering fluid—low fluid levels can cause the power steering pump to malfunction; or the steering pump itself might be broken, resulting in insufficient output pressure. For electronic power steering, the torque sensor might fail, unable to detect steering wheel movements; or the control module might malfunction, failing to send signals to drive the power assist. Electrical circuits should not be overlooked either—aging wires, loose connections, or blown fuses can all interrupt the current. A loose or broken belt can also stop the power steering pump. If you encounter this situation while driving, pull over immediately—don't push through, as losing control at high speeds is terrifying. You can quickly check the fluid reservoir to see if the level is normal, but the safest option is to take it to a professional repair shop for a thorough inspection. Safety comes first.
When power steering fails, the steering wheel becomes as heavy as dragging a heavy load. Common causes should be examined from the components. The power steering pump is critical; a faulty pump or insufficient oil pressure in the hydraulic system can cause the power assist to disappear. Leaking or contaminated steering fluid also has a significant impact. In terms of the electronic system, the torque sensor detects the steering wheel angle, and if it fails, there will be no response. If the control module has a short circuit or software malfunction, it may cause the power assist to shut down. Belt issues should also be checked, as a loose or worn belt can reduce pump rotation speed. Don't forget to check the battery voltage; electronic power steering relies on electrical power, and unstable voltage can trigger failure. Such failures are common in older or poorly maintained vehicles, and timely troubleshooting can avoid major repair costs.
Once while driving the MG GS, the power steering suddenly failed, and the steering wheel became extremely heavy. I suspect the issue might be due to low fluid levels—insufficient power steering fluid causing the assist to fail—or an electronic sensor malfunction, such as a faulty steering angle sensor. A loose belt is also a common issue, preventing the pump from working. Another possible cause is a blown fuse, where a short circuit causes an instant disconnection. It's a good habit to check the dashboard warning lights before each drive. If the power steering fails, pull over immediately and try checking and refilling the fluid reservoir. However, in most cases, it's safer to send the car for repairs, as this directly impacts driving safety.
