The valve provides position feedback to the hybrid/EV powertrain control module 2 based on a potentiometer in the valve. The hybrid/EV powertrain control module 2 uses this feedback to monitor the valve position. Different valve positions correspond to different resistance values. The hybrid/EV powertrain control module 2 determines the resistance values corresponding to the end stop positions of the valve by moving the valve to an end-stop and back to its original position when the vehicle is first turned on. This is referred to as the hybrid/EV powertrain control module 2
