P0DFAGenerator Phase U-V-W Current Sensor Correlation
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- Stop Safely Now or hybrid system warning
- Vehicle may not start or ready mode is refused
- Generator shut down, restricted driving
- Likely causes
- 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
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
