The torque sensor provides the PSCM with inputs of the steering torque applied by the driver. The torque sensor is installed at the junction between the input shaft and the pinion shaft, inside the steering gear housing.
Torque applied to the input shaft is transferred to the pinion shaft through the torsion bar, which twists under load. The torque sensor calculates the amount of twist in the torsion bar using a Hall effect sensor to monitor the angular position of the input shaft in relation to the pinion shaft, then transmits the result in a digital signal to the PSCM.
