P0E0B
Generator Phase W Current Sensor Circuit High
The generator phase W current sensor reports a circuit high fault. 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.
