P0CE7 Meaning

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 "diagnostic learn" the valve. This provides a valve shaft breakage test and allows the hybrid/EV powertrain control module 2 to "learn" the position feedback value that corresponds to that end-stop. The end-stop that is used at each Vehicle in Service Mode alternates between each end, the radiator end one time, the chiller end the next time, the radiator end the next time, etc.
