P0E10 means supply A of the generator inverter is present but too low. Ford lists the code in the HEV OBD system summary for its power-split hybrids (OBDSM1901): in the paragraph on the gate signal lines of motor and generator, P0E10 appears with P0BCE and P0BCF among the generator-side open-circuit faults, while the motor side is covered by P0C0C. For Ford, P0E10 is therefore tied to the gate drive path of the generator inverter rather than to a separate supply part, and no voltage limit is published. CARB requires circuit monitoring for such hybrid components. A weak gate drive supply can leave the power switches only partly turned on so they overheat, which is why the inverter limits or stops the generator. Siblings: P0E0F and P0E11.

Likely causes

Gate drive supply or gate signal path in the inverter faulty (Ford)
Low 12 V supply to the inverter, e.g. weak battery or poor ground
Corroded or loose inverter connector

Symptoms

  • Hybrid system warning light and MIL on
  • Generator limited or switched off, reduced hybrid performance
