P0E71 Generator Torque Delivered Performance

P0E71 compares the torque that the hybrid generator or motor-generator actually provides with the value requested by the hybrid control. If the two drift apart beyond a calibrated margin, the code is set. Ford uses it codegenau in its 2024 to 2025 gasoline OBD summary: in the three-byte format P0E71-48 replaces the older P061B for a motor torque plausibility error on vehicles with the modular hybrid transmission (MHT), rated MIL plus wrench lamp. The monitor runs continuously and needs less than one second to register a fault. Under CARB, powertrain components whose failure can raise emissions fall under the comprehensive component checks. Causes range from inverter faults and position sensor errors to winding damage. Expect reduced power, limited hybrid operation or a disabled hybrid system.

Likely causes

Fault in the inverter stage feeding the generator
Rotor position sensor (resolver) delivering a wrong angle
Control software needing an update
Damaged generator winding or internal contamination

Symptoms

  • MIL and service wrench lamp on (Ford)
  • Reduced power or emergency running mode
  • Engine runs more often, hybrid assistance missing
