P2DBE means the coupler lock sensor of charger B delivers a voltage below its valid band. No manufacturer documents P2DBE publicly. The A-side code P0DA0 is documented by Mitsubishi for the 2023 Outlander PHEV: with the ignition-controlled supply on, the PHEV-ECU sets it on a low input from the inlet's lock sensor. The repair flow first checks the signal line for a ground short between ECU and lock actuator connector, then checks the sensor itself, which should measure about 16.8 kΩ between its two pins. Damaged harness, the inlet cable assembly with its actuator, or the ECU are the named suspects. Ford also lists P0DA0 among the codes after a broken lock pin (TSB 23-2014). Too high is P2DBF. Charging via inlet B may be refused.

Likely causes

Sensor signal line shorted to ground
Lock position sensor with internal short or wrong resistance
Damaged lock actuator after the plug was pulled while latched
Faulty sensor input in the control module

Symptoms

  • Charging at inlet B refused
  • Charging system warning lamp or message
