What does code P2DB4 mean?

Q: What does code P2DB4 mean?

Drive Motor A Temperature Sensor C Circuit High. P2DB4 indicates that the powertrain control module has detected an abnormally high voltage on the signal circuit for temperature sensor C of drive motor A, which typically means the sensor circuit is open or shorted to a voltage source. The computer expects a voltage within a calibrated range that corresponds to a plausible motor temperature, and a sustained high reading falls outside that range.
