Q: What does code P2DBC mean?

Battery Charger B Coupler Lock Position Sensor Circuit. P2DBC indicates that the powertrain control module (PCM) has detected an abnormal signal from the coupler lock position sensor for battery charger B, which is part of the high-voltage charging system on electrified vehicles. The sensor monitors whether the charge coupler is fully latched before charging is allowed, and the PCM sets this code when the signal is out of range or inconsistent with the commanded lock state.
