P0A25 Generator Torque Sensor Circuit High
The generator torque sensor reports a circuit high fault. Generator torque feedback is unreliable. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
