What P0DFA means
In a three-phase machine the currents of phases U, V and W add up to nearly zero at every instant, so a sum far from zero shows that at least one current sensor is wrong. P0DFA is the code for this cross-check on the generator side. Mitsubishi documents it for the Outlander PHEV: with the IGBTs switching, the summation check must not report a failure, and with them off the sum must stay below 140 A; either condition held for 0.35 s sets P0DFA-00. Ford counts P0DFA among the generator inverter faults of its power-split hybrids, and SSM 50151 notes that on 2020 to 2021 hybrid models it can be caused by a 12 V dip at key-on, so check for low voltage first. Single-phase sensor faults are P0E00 to P0E0B.
P0DFA 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 P0DFA
- Stop Safely Now or hybrid system warning
- Vehicle may not start or ready mode is refused
- Generator shut down, restricted driving
Common causes of P0DFA
- Possible12 V voltage drop at key-on (Ford SSM 50151)
- PossibleOne phase current sensor with offset or gain error
- PossibleInternal fault of the inverter or power drive unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DFA means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| FA | The exact fault in that area. |
What to do next
- Note P0DFA 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 P0DFA
What does P0DFA mean?
P0DFA means "Generator Phase U-V-W Current Sensor Correlation". In a three-phase machine the currents of phases U, V and W add up to nearly zero at every instant, so a sum far from zero shows that at least one current sensor is wrong. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DFA?
Drive gently and only to a workshop. With P0DFA the car can go into limp mode (reduced power) to protect itself.
Will P0DFA fail an emissions test?
Yes, it can. P0DFA 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 P0DFA to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P0DFA clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
