What are the reasons for slow and weak return of electric power steering wheel?
4 Answers
Electronic power steering wheel returns slowly and weakly due to: 1. Insufficient oil pressure of the power pump; 2. Wear of the steering gear piston or vane valve; 3. Wear of the return switch paddle or steering wheel return slot. Features of electric power steering: 1. Strong adaptability; 2. Compact structure, easy installation; 3. High reliability, maintenance-free; 4. Self-diagnosis and safety control functions. Electric power steering mainly consists of torque sensor, speed sensor, motor, reduction mechanism and electronic control unit. The power steering systems configured on automobiles are generally divided into: mechanical hydraulic power steering system, electro-hydraulic power steering system and electric power steering system.
I've driven many cars and encountered slow steering wheel return issues. This is usually due to sluggish response from the electric power steering system's motor or sensors – they provide assistance and can fail when aged or dirty. Worn steering gears also slow down the return, especially noticeable during parking. Uneven tire pressure or tread wear can increase the burden. Another factor is that the power steering system software may be outdated and need updating. These faults may seem minor but actually affect turning precision, especially dangerous at high speeds. Don't delay, get the power unit and steering components checked at a professional shop as soon as possible. Regular maintenance can prevent these issues.
As a commuter who drives frequently, weak steering wheel return is quite frustrating. Power steering motor failures are common, especially when the battery supply is insufficient. Loose steering linkages or uneven tire wear can make it difficult for the wheel to return to center, affecting handling smoothness. Additionally, dust buildup on sensors can cause signal delays. After driving for a long time, I make it a habit to check tire pressure and suspension—simple actions that can prevent issues. If I notice slow return, I stop immediately to avoid risks—safety first, and only professional repairs can fully resolve hidden problems.
My experience is that slow steering wheel return is often due to software issues. Electric power steering relies on sensor data, and delays or errors can weaken the return force. Uneven tire wear can also interfere, such as low tire pressure making steering heavy. System memory lag can sometimes be alleviated by restarting. Paying attention to battery health in daily use can prevent power steering failure—don't overlook these small details to keep the system running smoothly.
