P0EEF Battery Charger Coupler Temperature B Too High
The coupler B temperature exceeds the safety threshold during charging. The on-board charger negotiates voltage, current and safety with the EVSE; a fault interrupts charging or limits it to AC slow-charge despite a DC fast charger being attached.
Is it safe to drive with P0EEF?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
