P00CD Fuel Volume Regulator Solenoid Supply Voltage Control Circuit High
Supply voltage to fuel volume regulator solenoid 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 P00CD?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelyAlternator regulator failed
- Less likelyConnector pins corroded - high contact resistance
- Less likelySupply wire pinched against B+ source
