Code P0CBE Cadillac Description

The hybrid electronics coolant temperature sensor is a variable resistor that measures the temperature of the starter/generator coolant. The Starter/Generator Control Module supplies 5 V to the signal circuit and a ground for the low reference circuit. The hybrid electronics coolant temperature sensor resistance changes with starter/generator coolant temperature. As the temperature decreases, the sensor resistance increases. As the temperature increases, the sensor resistance decreases. The Starter/Generator Control Module monitors the hybrid electronics coolant temperature sensor to determine the temperature of the starter/generator coolant. As the coolant temperature changes, the Starter/Generator Control Module will turn the Starter/Generator Control Module coolant pump ON or OFF to accommodate the starter/generator cooling requirements.
The Starter/Generator Control Module performs a rationality diagnostic that compares the hybrid electronics coolant temperature sensor signal to the average temperature of the starter/generator stator, engine intake air temperature, and transmission fluid temperature. This diagnostic gets one chance to run during a drive cycle after a specific vehicle OFF time.
