What P00CD means

P00CD
Fuel Volume Regulator Solenoid Supply Voltage Control Circuit High Generic · fuel Data confidence 65%

The control module detected that the signal in the Fuel Volume Regulator Solenoid Supply Voltage Control circuit stayed above the expected operating range.

Symptoms

  • Possible hard starting or long cranking
  • Possible reduced power or cutting out
  • MIL illuminated

Possible causes

  • Low-pressure fuel supply fault (pump, filter, lines)
  • High-pressure pump wear or fault
  • Pressure regulator / volume control valve fault
  • Fuel pressure sensor fault
  • Internal leakage (injector return flow too high)

Recommended checks

  • Read specified vs actual rail pressure at cranking, idle and load
  • Check low-pressure supply (pressure/volume) first
  • Check control valve/regulator operation
  • Measure injector return flow where applicable
  • Inspect wiring and connectors of pressure components

Frequently asked questions about P00CD

What does P00CD mean?

Fuel Volume Regulator Solenoid Supply Voltage Control Circuit High. The control module detected that the signal in the Fuel Volume Regulator Solenoid Supply Voltage Control circuit stayed above the expected operating range.

Is P00CD generic or manufacturer-specific?

P00CD is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove P00CD at file level?

If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
