What does code P0BD3 mean?

Q: What does code P0BD3 mean?

Drive Motor Inverter Temperature Sensor C Circuit Low. P0BD3 indicates that the powertrain control module has detected an abnormally low voltage signal on the temperature sensor circuit for the drive motor inverter, specifically the channel designated as Sensor C. This sensor monitors the inverter's operating temperature, and a low signal means the circuit is likely shorted to ground, has excessive resistance, or the sensor itself has failed.
