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.
High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.
Symptoms
- Hybrid or engine warning light on
- Generator power reduced as a precaution
- Higher engine use or weaker battery recharge
Most 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
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- It can trigger limp mode.
- It affects emissions.
What each character of P0DF2 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- D: Subsystem depends on the code range
- F2: Specific fault in that system
Frequently asked questions
