P0092 Fuel Pressure Regulator A Control Circuit High
Fuel pressure regulator A control voltage above expected range — short to power or open ground. 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 P0092?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
