Can Electronic Power Steering Be Repaired?

It can be repaired, but it is not recommended to repair the electronic power steering system. It is best to replace it directly. Below is relevant information: Classification: Steering pumps mainly include vane, gear, and plunger types. Currently in China, vane pumps are the most widely used. Main components include the stator, rotor, oil distribution plate, vanes, pump body, and rear cover. The pump body is equipped with a flow control valve and a safety valve. When the pump operates, the spool valve opens to a certain extent to meet flow requirements, with excess flow returning to the pump's suction chamber. Precautions: If the oil passage is blocked or an accident occurs, causing the system pressure to exceed the pump's maximum working pressure, the safety valve opens, the spool fully opens, and all pressure oil returns to the suction chamber, providing system safety protection.

Last year, my car had an issue with the electronic power steering, making it extremely heavy to turn. I took it to a familiar repair shop for inspection, and the mechanic said the brushes inside the motor were worn out. After disassembling, cleaning, and replacing them, it returned to normal and has been working fine for over a year now. In fact, common repairs for electronic power steering systems nowadays include replacing motor brushes, calibrating the torque sensor, and removing rust from control module ports. The cost is often only one-third of replacing a new steering gear. However, be cautious if the steering gear housing is deformed or there is extensive corrosion in the wiring—in such cases, it’s advisable to replace the entire unit. Before heading to the repair shop, it’s best to have the mechanic read the fault codes with a diagnostic tool to avoid being misled by unprofessional shops into replacing the entire system. Since the steering system is safety-critical, after repairs, make sure to test several sharp turns in a parking lot to ensure there are no abnormal noises at any angle.

Electronic power steering can indeed be repaired, depending on the fault location. Last time I encountered steering wheel vibration, diagnosis revealed torque sensor misalignment which was corrected through calibration. Common repair points include sensor calibration, motor bearing replacement, and electronic control module soldering - minor issues costing a few hundred yuan. However, if internal gear set wear or seal failure causes water ingress, the entire assembly needs replacement, doubling the cost. It's advisable to inspect immediately when abnormal noises occur or steering becomes heavy, rather than waiting for complete failure. Modern repair shops can use diagnostic computers to retrieve torque data for precise fault location identification, making repairs far more cost-effective than outright replacement. After repair, always perform steering angle reset, otherwise high-speed driving may feel unstable.

Electronic power steering can certainly be repaired, but it depends on the specific situation. I've encountered cases where the motor coil was burnt out, and rewinding the coil fixed it; a friend had water damage corroding the control module, and cleaning the contacts solved the issue. The key to repair lies in accurate diagnosis - professional shops using oscilloscopes to detect current waveforms can precisely locate faults. Common repair items include motor brush replacement, sensor demagnetization treatment, and circuit board solder joint reinforcement. However, if the reduction gear is damaged or the steering angle limiter fails, repair costs may approach replacement part prices. After steering system repairs, road testing is mandatory - simulating various turns to confirm no sticking sensation before approval. Daily care like avoiding holding the steering wheel at full lock for over 3 seconds can extend the power steering system's lifespan.
