P0E09 Generator Phase W Current Sensor Circuit Range/Performance
The generator phase W current sensor reports a circuit range/performance 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.
Is it safe to drive with P0E09?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
