This summary uses the existing diagnostic information shown in full below.
This code means the car's computer found a problem with the sensor that checks how hot or cold the coolant is for the motor that helps the car move.
The P0CBC code is triggered when the vehicle's powertrain control module (PCM) detects an issue with the coolant temperature sensor circuit for Drive Motor A.
The Drive Motor A Coolant Temperature Sensor is responsible for monitoring the temperature of the coolant used to cool the electric motor. If the sensor circuit is open, shorted, or otherwise malfunctioning, the PCM will set the P0CBC code. This can affect the motor's efficiency and potentially lead to overheating.
• Check Engine Light illuminated
• Reduced vehicle performance
• Possible overheating of the drive motor
• Faulty coolant temperature sensor
• Damaged wiring or connectors
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Scan the vehicle for additional trouble codes.
• Inspect the wiring and connectors for damage.
• Test the coolant temperature sensor for proper operation.
• Replace the coolant temperature sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure coolant levels are adequate
• Inspect wiring for wear and tear
Sensor Issue
• Do not ignore the Check Engine Light.
• Get the vehicle inspected by a professional.
• Monitor coolant levels regularly.
Check with your vehicle manufacturer for warranty coverage on the powertrain components.
This code has become more common with the increased use of electric and hybrid vehicles, where motor cooling is crucial.
Moderate – Addressing this issue promptly can prevent further damage to the drive motor.
Operating a vehicle with a malfunctioning coolant sensor can lead to overheating and potential safety hazards.
• Vehicle at operating temperature
• Engine running
The Drive Motor A Coolant Temperature Sensor is typically located near the drive motor or integrated into the cooling system.
Q: Can I drive with a P0CBC code?
A: It's not recommended to drive for long periods with this code, as it may lead to overheating and damage to the motor.
Q: How can I reset the P0CBC code?
A: The code can be reset with an OBD-II scanner, but it's important to fix the underlying issue first.

Fitment Required · Vehicle-fitment part
Relevant when coolant-temperature and warm-up faults indicate a thermostat-related issue.
Coolant-temperature and warm-up faults often lead to thermostat testing and replacement.
Thermostats are vehicle-specific and should be matched by engine and housing style.
