P0CBF Code - Drive Motor Coolant Temperature Sensor Circuit High 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 P0CBF 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 P0CBF?
- 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
How to Fix the DTC P0CBF?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0CBF code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
