P025D Fuel Pump Module A Control Circuit High
Fuel pump module A control voltage above expected range. 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 P025D?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
