What is EPS torque sensor?
What is EPS torque sensor?
One of the most critical parts in an EPS application is the torque sensor, which collects steering direct and road resistance input and communicates the torque, or the amount of turning force, back to the EPS control module.
Where is the torque sensor located in an electric power steering system?
The sensor sits on the steering pinion. A pole wheel is fitted on the input shaft, which is connected to the steering pinion by means of the torsion bar. When the driver applies torque to the steering wheel, the torsion bar is rotated and, in turn, the magnet relative to the sensor.
Under what conditions would and EPS electric power steering require a torque sensor zero point calibration?
The torque sensor zero point should be calibrated whenever you remove and replace the steering column assembly (containing the torque sensor), power steering ECU assembly, steering wheel steering gear assembly, and if a difference is felt in steering effort between right and left. 1.
How do you diagnose EPS?
Tips For Diagnosing EPS Issues. The main indication you’ll get if there is a malfunction with the electric power steering system is that the EPS light will illuminate on the dashboard. Specifically, the warning light will come on when the EPS system is off.
What sensors are needed for EPS systems?
Steering Sensors Used in EPS Systems Three primary different steering sensor types make this outstanding level of performance possible: Steering position sensors, steering torque sensors, and steering sensors that offer a combination of the two.
Where is the EPS located?
EPS is a relatively simple system. The steering shaft torque sensor, located in a section of torsion bar in between the steering input and output shafts, is the PSCM’s main input for determining steering direction and the amount of assist needed.
What is EPS control module?
Purpose/ Function. The EPS control module (CM) calculates the optimum assist current based on the steering torque signal from the torque sensor installed to the steering column and the vehicle speed signal sent via CAN transmission from the PCM.
What causes EPS malfunction?
What Is EPS Malfunction And Why Does It Occur? When the steering wheel gets struck or disengages from the electric motor, EPS malfunctioning occurs. It usually happens because of the rust and water inside the arch or aging of the tightening rubbers.
What causes EPS problems?
EPS outage can be caused by a car battery, an alternator or a circuit fault. Regular checkup should be provided for all those car elements.
