P0E0E
Generator Phase U-V-W Circuit High
The generator phase U-V-W output reports a circuit high condition. 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.
