P00CC Fuel Volume Regulator Solenoid Supply Voltage Control Circuit Low

Supply voltage to fuel volume regulator solenoid below 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.
