P0DF2 covers an electrical fault on temperature sensor C of the generator inverter that the controller cannot assign to a more specific low, high or intermittent code. Which power switch carries sensor C is up to the manufacturer; in Mitsubishi's Outlander PHEV the third high-side IGBT sensor sits on the W phase, and its faults are logged only as P0DF7 to P0DF9. No manufacturer documents P0DF2 itself. CARB demands circuit monitoring for inputs of inverter thermal management. As these thermistors are usually built into the IGBT module, a confirmed sensor fault often means replacing the inverter or the complete power unit, so the harness and connector deserve a careful check first. The general circuit code for sensor B is P0DF0.

Likely causes

Thermistor inside the IGBT module defective

Connector or signal line fault between module and controller

Faulty input stage in the generator control unit

Symptoms

Hybrid or engine warning light on
Generator power reduced as a precaution
Higher engine use or weaker battery recharge
