Why Does the Electric Power Steering Become Heavier?
3 Answers
The reasons for the electric power steering becoming heavier include the following: 1. Low tire pressure causes the steering to become heavier at low speeds. 2. A depleted car battery, especially if it has been used for a long time, can affect the normal output of the electric power steering. 3. Abnormal shock absorbers or significant alignment data deviation. It is necessary to check whether the plane bearing on top of the shock absorber is functioning properly. 4. A malfunctioning torque sensor, where damaged transistors or diodes inside the sensor cause the pulse signal range to vary significantly, preventing the control module from performing effective calculations.
My electric power steering has become heavier, which is a fairly common issue with multiple potential causes. It could be a faulty sensor responsible for detecting steering wheel movement—when it malfunctions, power assistance weakens. Alternatively, the assist motor may have failed due to aging or wear. Software glitches in the control system might also require reprogramming or updates. Power supply issues like low battery voltage or oxidized connectors can cause unstable system operation. From my experience, start by checking the battery status and whether fuses are blown—these are simple fixes that can rule out basic problems. If that doesn’t resolve it, visit a professional repair shop promptly to avoid long-term damage to other components. Heavy steering is particularly dangerous at highway speeds—never ignore it. Regular maintenance checks on the steering system can prevent such issues and ensure safe, smooth driving.
I've also experienced the steering wheel becoming heavier, which is really a headache. The issue might lie in the motor or sensors of the power steering system—they're too sensitive and can malfunction when dirty or aged; sometimes it's the vehicle's computer control unit acting up, requiring a software refresh. Battery aging is a major factor, as low voltage slows down system response. My approach is to first check if any warning lights are illuminated on the dashboard, then test the battery voltage to ensure it's normal. If the symptoms persist, don't hesitate to consult a mechanic immediately. Heavy steering not only makes driving exhausting but can also increase tire wear and compromise safety. Paying attention to these details during maintenance can extend your car's lifespan, saving you money and peace of mind.
