What does code P2BDF mean?

Q: What does code P2BDF mean?

Motor Electronics Coolant Temperature Sensor C Circuit High. P2BDF indicates that the engine control module has detected an abnormally high voltage on the signal circuit for the motor electronics coolant temperature sensor C, which is typically a second or auxiliary temperature sensor used by the hybrid or electric motor electronics cooling system. The circuit is expected to operate within a specific voltage range, and a high reading usually means the sensor signal wire is open, shorted to voltage, or the sensor element itself has failed.
