P00CC medium Severity

P00CC: Fuel Volume Regulator Solenoid Supply Voltage Control Circuit Low

Potential fuel pressure regulation issues leading to rough running, reduced performance, or emissions faults

Overview

P00CC OBD-II code indicates low voltage in the fuel volume regulator solenoid supply voltage control circuit, typically a generic powertrain fuel/air metering electrical circuit issue

Common Symptoms

  • Check Engine Light illuminated
  • Poor engine performance or hesitation
  • Potential fuel pressure abnormalities

Most Common Causes

Low voltage in fuel volume regulator solenoid circuit (wiring/connectors) high

Circuit voltage low condition triggers this generic trouble code

Weak battery or charging system issue medium

Insufficient supply voltage can lead to low voltage detection

Faulty fuel volume regulator solenoid medium

Component failure can disrupt supply voltage

Faulty ECM/PCM low

ECM fault may misreport circuit conditions

Diagnostic Steps

  1. Connect OBD-II scanner and confirm P00CC code along with any freeze-frame data
    Expected: P00CC present without conflicting codes
    Interpretation: Confirms the issue pertains to the fuel volume regulator solenoid control circuit
  2. Measure circuit supply voltage at the fuel volume regulator solenoid and check battery and charging system voltage
    Expected: Normal battery voltage (around 12.6–14.4V with engine running)
    Interpretation: Low voltage indicates wiring/connection or supply issue
  3. Inspect wiring harness and connectors for corrosion, damage, or poor connection
    Expected: Clean, secure connections with no damage
    Interpretation: Faulty wiring requires repair
  4. Test or replace fuel volume regulator solenoid if wiring and voltage checks are normal
    Expected: Proper operation and restored voltage
    Interpretation: Component replacement resolves code

Repair Solutions

Repair or replace damaged wiring/connectors in the solenoid supply circuit medium
Estimated Cost: $50 - $250

Costs vary based on extent of wiring harness repair

Replace fuel volume regulator solenoid medium
Estimated Cost: $200 - $600
