P0CBE Code - Drive Motor Coolant Temperature Sensor Circuit Low Voltage
Quick Answer
The hybrid electronics coolant temperature sensor is a variable resistor that measures the temperature of the starter/generator coolant. Common causes include Faulty Starter/Generator Coolant Temperature Sensor, Starter/Generator Coolant Temperature Sensor harness is open or shorted, Starter/Generator Coolant Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0CBE Description
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.
What are the Possible Causes of the DTC P0CBE?
- Faulty Starter/Generator Coolant Temperature Sensor
- Starter/Generator Coolant Temperature Sensor harness is open or shorted
- Starter/Generator Coolant Temperature Sensor circuit poor electrical connection
- Faulty Starter/Generator Control Module
