P0E11 is stored when supply A of the generator inverter is above its permitted range. Overvoltage on the gate driver feed can overstress the control inputs of the power transistors, so controllers usually react by blocking the inverter. No manufacturer documents P0E11 publicly. Ford's hybrid summary shows that such supplies are watched: a gate drive power supply above 15.08 V counts as a fault there, though Ford files it under a rotor position circuit voltage check and not under P0E11. CARB asks for circuit fault detection on hybrid parts. A short between two supply rails or a faulty regulator inside the inverter are the likely causes; a charging system fault on the 12 V side can also contribute. Siblings: P0E0F and P0E10; supply B high: P2CC7.

Likely causes

Voltage regulator of the gate driver supply in the inverter faulty
Short between two internal supply rails
Overvoltage in the 12 V system (DC/DC converter or charging fault)

Symptoms

  • Hybrid system warning light and MIL on
  • Generator blocked, no charging while driving
