P2DC0Battery Charger B Coupler Lock Position Sensor Circuit Intermittent/Erratic

P2DC0 indicates that the powertrain control module has detected an intermittent or erratic signal from the coupler lock position sensor in the battery charger B circuit, which is typically part of a high-voltage charging system on electrified vehicles. The computer sets this code when the sensor voltage momentarily drops out or jumps outside its expected range, preventing reliable confirmation that the charge coupler is fully locked.
