What are the causes of Baojun electronic power steering failure?
3 Answers
Reasons for heavy steering failure: 1. Power steering system: The power steering system contains a large amount of air, causing abnormal car steering; 2. Steering hydraulic pipeline: Foreign objects in the steering hydraulic pipeline cause the steering pump flow control valve to stick; 3. Power steering system: Loose connections in the power steering system lead to steering fluid leakage; 4. Steering gear piston cylinder: Excessive wear of the steering gear piston cylinder, poor oil seal sealing, and damaged control valve. More related information is as follows: Notes: If the steering warning light is yellow, it means the steering system is partially failing, requiring more effort to steer the wheel. If the steering warning light is red, then the steering system has completely failed, and it takes a lot of effort to turn the steering wheel.
As a long-time Baojun owner, I've seen quite a few common causes for electric power steering failures, mainly related to its power supply or sensing system. Power issues are the most frequent - if the battery dies or the alternator fails, the power steering system loses electricity and stops working immediately. Then there are sensor failures, like when the torque sensor on the steering wheel gets damp or ages, preventing signals from reaching the computer module. Wiring problems are also common - loose connectors, burnt wires or short circuits can interrupt current flow. The motor itself can malfunction too, with bearing wear or burnt-out motors making steering impossible. Sometimes software bugs cause trouble, requiring control module updates. When my car lost power steering before, I pulled over and found a blown fuse - replacing it fixed the issue. I recommend regular battery maintenance and sensor checks to avoid roadside breakdowns - these failures are both inconvenient and dangerous. Safety first - this veteran advice shouldn't be ignored.
I usually pay close attention to automotive technology. Baojun electric power steering failures can generally be categorized into several types. First, there are sensor-related issues, such as contamination or damage to the steering angle sensor on the steering wheel, which prevents the data from being properly processed by the computer module. Problems with the control unit are also common—ECU circuit board overheating, short circuits, or software freezes can cause intermittent power assistance. Wiring issues shouldn’t be overlooked either; poor grounding or aging, damaged wiring harnesses can lead to signal loss or excessive current blowing fuses. Motor failures are frequent as well, such as overheated and deformed coils or jammed gears preventing rotation. Insufficient power supply is another major issue, like a drained battery or unstable alternator voltage affecting the system. I recommend owners use a multimeter to check voltage and resistance for basic troubleshooting. Don’t panic—stay calm, pull over safely, and seek professional diagnosis for peace of mind. Understanding these issues helps with early prevention.
