What P0DF8 means
P0DF8 tells that temperature sensor C in the generator inverter delivers a voltage below its valid range. Mitsubishi uses the code in the Outlander PHEV for the W-phase high-side IGBT sensor: a reading at or under 1.25 V for 0.08 s, with at least 8 V GCU supply, stores P0DF8-00, and the check runs all the time. Physical causes are a short between signal and ground or a breakdown inside the module, for instance after coolant has reached the electronics. The value suggests a far too hot switch, so the controller derates the generator to stay on the safe side. The sensor cannot be replaced on its own, which is why Mitsubishi lists the power drive unit. The same fault on sensor B is P0DF5, the high case on this sensor P0DF9.
P0DF8 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0DF8
- Hybrid or engine warning light on
- Generator power limited
- Implausibly high inverter temperature in live data
Common causes of P0DF8
- PossibleSignal line of sensor C shorted to ground
- PossibleShorted sensor or internal fault of the power drive unit
- Less likelyCoolant or moisture inside the inverter electronics
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DF8 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| F8 | The exact fault in that area. |
What to do next
- Note P0DF8 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 P0DF8
What does P0DF8 mean?
P0DF8 means "Generator Inverter Temperature Sensor C Circuit Low". P0DF8 tells that temperature sensor C in the generator inverter delivers a voltage below its valid range. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DF8?
Drive gently and only to a workshop. With P0DF8 the car can go into limp mode (reduced power) to protect itself.
Will P0DF8 fail an emissions test?
Yes, it can. P0DF8 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 P0DF8 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P0DF8 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
