P006F medium Severity

P006F: Turbocharger/Supercharger Boost Control A Supply Voltage Circuit High

Reduced engine power and possible limp mode due to improper boost control

Overview

P006F indicates a high voltage condition in the turbocharger or supercharger boost control 'A' supply voltage circuit, often caused by electrical or actuator faults affecting forced induction boost regulation.

Common Symptoms

  • Check Engine Light illumination
  • Reduced or erratic engine power
  • Decreased throttle response
  • Potential limp/reduced power mode
  • Poor fuel economy

Most Common Causes

Faulty boost control solenoid or actuator medium

Electronic actuator may fail internally or present high voltage readings

Damaged or corroded wiring or connectors in the boost control circuit high

Common cause due to exposure to heat and environment

Poor PCM power supply or ground reference medium

Voltage reference issues can present high circuit readings

Defective PCM low

Considered rare and usually after ruling out wiring and components

Diagnostic Steps

  1. Use an OBD-II scanner to confirm P006F and check for related codes
    Expected: Code P006F present with possible related boost control codes
    Interpretation: Confirms circuit high voltage condition
  2. Visually inspect wiring and connectors to the boost control solenoid/actuator
    Expected: Look for damage, corrosion, loose or melted insulation
    Interpretation: Damage would indicate likely electrical cause
  3. Measure circuit voltage at the boost control actuator compared to OEM specs
    Expected: Voltage within specified range
    Interpretation: High reading confirms circuit supply issue
  4. Check PCM power supply and ground reference
    Expected: Stable reference and grounds
    Interpretation: Faulty reference may cause false high voltage reading
  5. Replace suspect actuator/solenoid and clear codes
    Expected: Code should not return with correct component
    Interpretation: Indicates actuator/solenoid was root cause

Repair Solutions

Replace boost control solenoid/actuator medium
Estimated Cost: $200 - $800

Costs vary widely by make/model and part pricing

Repair or replace damaged wiring and connectors medium
Estimated Cost: $50 - $300

Depends on extent of wiring damage

Repair PCM power supply or ground circuits hard
Estimated Cost: $100 - $600

May require professional diagnostic and soldering

Replace PCM (last resort) hard
Estimated Cost: $500 - $2000

Only if confirmed faulty after all other diagnostics

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Faulty turbocharger unit instead of boost control circuit issue
