What P00CB means

P00CB
Fuel Volume Regulator Solenoid Supply Voltage Control Circuit/Open Generic · fuel Data confidence 65%

The control module detected an interruption (open circuit) in the Fuel Volume Regulator Solenoid Supply Voltage Control circuit, so the expected electrical continuity was not present.

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 P00CB

What does P00CB mean?

Fuel Volume Regulator Solenoid Supply Voltage Control Circuit/Open. The control module detected an interruption (open circuit) in the Fuel Volume Regulator Solenoid Supply Voltage Control circuit, so the expected electrical continuity was not present.

Is P00CB generic or manufacturer-specific?

P00CB is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove P00CB at file level?

If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
