P0E5D DC/DC Converter Enable Circuit Intermittent/Erratic
The DC/DC converter enable signal drops out or jumps intermittently. 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 P0E5D?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
