P008E
Fuel Cooler Pump Control Circuit High
Control voltage of the fuel cooler pump is above the 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.
