|What are the Possible Causes of the P0CBD Code?

  • 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 P0CBD Code?

Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

|What is the cost to diagnose the P0CBD code?

Labor: 1.0

The cost to diagnose the P0CBD code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|What are P0CBD code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)

|What Does the P0CBD Code Mean?

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.
