P2DBCBattery Charger B Coupler Lock Position Sensor Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P2DBC is the general circuit fault of the lock position sensor at charger B's coupler, the feedback telling the vehicle whether the pin that holds the charging plug in the inlet has moved out or back in. B marks a second inlet or charging path. No manufacturer documents P2DBC publicly. GM's patent US8936482B2 shows how such feedback can work: an angle sensor on the actuator motor shaft yields the pin travel, and fast charging is withheld if the lock cannot be confirmed. On the A side Ford stores P0D9E:00 in the SOBDM of 2021–2023 Mach-E, F-150 Lightning and e-Transit after the DC plug was pulled without pressing the release button, which damages the pin (TSB 23-2014); only the lock actuator is replaced. Specific fault types follow in P2DBD to P2DC0.
