What P0DF2 means
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.
P0DF2 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0DF2
- Hybrid or engine warning light on
- Generator power reduced as a precaution
- Higher engine use or weaker battery recharge
Common causes of P0DF2
- PossibleThermistor inside the IGBT module defective
- PossibleConnector or signal line fault between module and controller
- Less likelyFaulty input stage in the generator control unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DF2 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| F2 | The exact fault in that area. |
What to do next
- Note P0DF2 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0DF2
What does P0DF2 mean?
P0DF2 means "Generator Inverter Temperature Sensor C Circuit". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DF2?
Drive gently and only to a workshop. With P0DF2 the car can go into limp mode (reduced power) to protect itself.
Will P0DF2 fail an emissions test?
Yes, it can. P0DF2 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0DF2 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0DF2 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
