P2DAE means the sensor B voltage has fallen below the lowest value a healthy sensor can deliver. Winding probes are mostly NTC thermistors whose resistance collapses as they heat – Thinking Electronic quotes roughly 0.46 kOhm at 180 °C for its stator probes – so with the usual pull-up circuit a near-zero voltage would read as an impossibly hot winding. In practice it points to a short: signal lead to ground or to the motor housing, a shorted thermistor, or a lead pinched during assembly. On the 2023 Outlander PHEV, Mitsubishi's own code P3053 catches its V-phase probe when the signal stays at or under 0.1 V for half a second, provided the power drive unit has at least 8 V. No manufacturer documents P2DAE publicly. P2DAF is the opposite fault; real overheating would be P0A2F.

Likely causes

Sensor B signal lead shorted to ground or motor housing
Thermistor shorted internally (often replaceable only with the motor)
Lead pinched or chafed after work on the drive unit

Symptoms

  • Hybrid system warning or check engine light
  • Sensor B shows an extremely high fixed temperature in live data
  • Electric drive power reduced
