DTC codes / P0Bxx · Hybrid propulsion / P0BD5
P0BD5 indicates that the drive motor inverter temperature sensor C circuit is reporting intermittent or erratic signals to the vehicle's control module. The computer detects this when the sensor's voltage or resistance readings jump unpredictably or drop out momentarily, rather than staying within a stable expected range.
