Q: What does code P2DBF mean?

Battery Charger B Coupler Lock Position Sensor Circuit High. P2DBF indicates that the powertrain control module has detected an abnormally high voltage on the circuit that reports the lock position of the battery charger B coupler. This sensor tells the module whether the coupler is fully engaged, and a high signal usually means the circuit is open, shorted to voltage, or the sensor's internal resistance has risen.
