The torque sensor is the main input that the PSCM uses to determine the steering direction and the
amount of assist to provide. The steering column input and output shafts are separated by a torsion bar
that has the sensor mounted to it. The sensor is a dual signal sensor similar to the model that Ford uses.
The sensor is a 5 volt sensor that operates between 0.25 and 4.75 volts. When the steering wheel is
turned to the right the sensor 1 voltage will increase while the sensor 2 voltage decreases. The opposite
occurs on a left hand turn.
The steering wheel position sensor is used by the PSCM to determine when the steering wheel is in the
centre position. The PSCM uses the position sensor to help return the steering wheel to the centre
position. The sensor is a 5 volt analogue triangle sensor that will operate between 0 and 5 volts and the
sensor voltages will stay within 2.5 to 2.8 volts of each other.
