P2DB5Drive Motor A Temperature Sensor C Circuit Intermittent/Erratic

P2DB5 indicates that the powertrain control module has detected an intermittent or erratic signal from the temperature sensor circuit that monitors drive motor A, specifically the sensor designated as C. The computer expects a stable voltage or resistance reading that corresponds to a plausible motor temperature, but the signal is jumping, dropping out, or otherwise behaving unpredictably, which prevents reliable temperature protection of the electric drive motor.
