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.

Likely causes

12 V voltage drop at key-on (Ford SSM 50151)

One phase current sensor with offset or gain error

Internal fault of the inverter or power drive unit

Symptoms

Stop Safely Now or hybrid system warning
Vehicle may not start or ready mode is refused
Generator shut down, restricted driving
