|What Does the P0CEA Buick Code Mean?

The hybrid/EV electronics coolant pump circulates coolant through the power electronics coolant radiator, hybrid/EV powertrain control module 1 and the battery charger to control the temperature of the hybrid/EV powertrain control module 1 and the battery charger. An enable signal from the hybrid/EV powertrain control module 2 to the hybrid/EV electronics coolant pump provides overall control of the pump. When this circuit is high, the pump can operate. The pump is controlled with a pulse-width modulated signal from the hybrid/EV powertrain control module 2 to the hybrid/EV electronics coolant pump. The higher the duty cycle the higher the pump speed. The hybrid/EV electronics coolant pump provides a hard-wired pulse-width modulated feedback signal to the hybrid/EV powertrain control module 2. During normal operation, this feedback signal provides pump speed information. The hybrid/EV electronics coolant pump has some self-diagnostic capability. If it determines there is an internal fault it provides this information on this same feedback circuit instead of pump speed information.
