Electric power steering (EPS) is a modern system that facilitates driving by reducing the effort required to steer a vehicle’s wheels. Comprised of an electric motor, sensors, and a computer, it replaces traditional hydraulic systems by providing precise and energy-efficient electronic control. However, in the event of a malfunction, it becomes crucial to know how to correctly reset this system to ensure optimal operation and driver safety. Electric power steering (EPS) is a modern system that facilitates steering control by reducing driver effort through the use of an electric motor, sensors, and a computer. In the event of an electronic problem, a reset is often necessary to restore the system to optimal functionality. This detailed guide presents the operating principles of electric power steering, the symptoms indicating a malfunction, and several reliable methods for resetting it, thus ensuring safety and driving comfort. How Electric Power Steering Works Electric power steering replaces traditional hydraulic systems by integrating an electric motor controlled by a computer. A torque sensor measures the forces exerted on the steering column and its position. This information is transmitted to the computer, which orchestrates the appropriate assistance force that the motor applies to the steering rack, thus facilitating wheel steering. This technology saves fuel because assistance is only provided when the driver needs it. It differs from hydraulic systems, which require a pump, oil, and a hydraulic circuit, all potential sources of leaks and complex maintenance. Symptoms of an Electric Power Steering Malfunction A number of signs may indicate that your electric power steering is faulty. For example, a stiff steering wheel may indicate a lack of assistance, as may a steering wheel that moves slowly or with excessive resistance. Abnormal noises, such as squeaking, and the illumination of a specific warning light on the dashboard are also indicators of a fault. These symptoms should prompt you to quickly check the condition of your electric power steering to prevent premature tire wear and a potentially dangerous loss of traction.
Methods for Resetting Your Electric Power Steering Manual System Self-Calibration For some vehicles, particularly newer ones, a self-calibration process may be sufficient. This involves turning on the ignition without starting the engine, then turning the steering wheel from lock to lock, first to the right, then to the left, to recalibrate the sensors. This mechanical maneuver involves resetting the sensors and recalibrating the power assistance to restore normal steering behavior. However, this method is not applicable to all models and may require facilitating wheel movement, for example, by slightly moistening the tires to reduce road friction.
Automatic Reset While Driving
Some modern cars incorporate an automatic reset mechanism activated when driving at a steady speed, such as on a highway. By maintaining a straight trajectory at a sufficient speed, the computer can recalibrate the steering sensors without manual intervention. This method is convenient, but will not work at low speeds or under conditions of frequent maneuvering. Using a professional electronic diagnostic tool In most cases, it is necessary to use an electronic diagnostic tool to perform a complete reset. These devices, available from equipped garages, allow for precise error identification via diagnostic codes, then initiate a reset procedure. This operation ensures proper calibration of the power steering system’s electronic components and often resolves electronic faults related to the ECUs. To learn more about this method, consult specialized resources such as Mister Auto or APTA. Additional tips for maintaining your electric power steering system In addition to the reset, it is recommended to regularly check the battery voltage, as insufficient power can disrupt the system. Similarly, examining the fuse box can rule out the possibility of a simple electrical fault. Finally, if the reset is unsuccessful, it is essential to consult a professional to check the integrity of the ECU or other sensitive electronic components.

Unlike hydraulic steering, EPS uses an electric motor, a computer, and sensors. When a malfunction occurs, a reset is often necessary to restore optimal assistance. This practical guide explains the operating principles, symptoms of a fault, and methods for resetting your electric power steering system. How Electric Power Steering Works
Electric power steering operates using an electric motor controlled by a computer. The system uses a torque sensor that measures the force applied to the steering column and the position of the steering wheel. This information is transmitted to the computer, which adjusts the assistance provided by the motor to facilitate wheel steering. This electronic process also reduces fuel consumption and pollutant emissions, as the assistance is only activated when necessary. Symptoms of a Power Steering Malfunction
Several signs may indicate a problem with the electric power steering:
Hard steering wheel
: Often related to a malfunction in the electronic system rather than a hydraulic problem.
Slow or stiff steering wheel
: May indicate a faulty power steering pump.
Squeaking or unusual noises when steering. Power steering warning light illuminated on the dashboard. It is important to recognize these symptoms quickly to avoid premature tire wear or loss of traction, which can compromise safety. Methods to reset the electric power steeringSeveral techniques exist to reset the electric power steering system:
Steering wheel self-calibration
This method involves self-calibrating the sensors. It is applicable to some recent vehicles. To do this, place the key in the ignition without starting the engine, then turn the steering wheel fully left and then right several times. This action recalibrates the torque sensors. If you have difficulty turning the steering wheel fully, a little water under the tires can help facilitate this process.
Resetting by driving at highway speeds Some modern car models have an automatic recalibration system activated by driving at a steady speed on the highway. By driving straight ahead at high speeds, the sensors gradually reset, which can correct power steering anomalies. Using an electronic diagnostic tool The most reliable method is to use a professional electronic diagnostic tool. This device allows you to read the error code generated by the computer and initiate a suitable reset procedure. This type of tool is generally available at specialized garages, as it represents a significant investment. By following the instructions displayed on the diagnostic software, it’s possible to reset the electric power steering and identify any faulty parts.When should you consult a professional?
