P006F Fault Code

P006F OBD-II Trouble Code Short Description

Turbocharger/Supercharger Boost Control "A" Supply Voltage Circuit High

What does trouble code P006F mean?

The P006F fault code refers to the Turbocharger/Supercharger Boost Control "A" Supply Voltage Circuit High. This code indicates that there is a problem with the supply voltage circuit of the turbocharger or supercharger boost control system.

The turbocharger or supercharger boost control system is responsible for increasing the intake air pressure and thus improving the engine's performance. The system uses various sensors and components to regulate the boost pressure.

When the P006F code is triggered, it means that the voltage in the supply circuit is higher than the predetermined value. This could be due to a faulty sensor, a malfunctioning wiring harness, or a problem with the control module.

To diagnose and resolve this issue, the following steps can be taken:

  1. Inspection of the wiring and connectors: Check for any loose connections, damaged wires, or corrosion in the circuitry. Repair or replace any faulty components.

  2. Check the boost control sensor: Ensure that the boost control sensor is functioning correctly. If necessary, replace the sensor.

  3. Test the boost control solenoid: Verify that the boost control solenoid is operating properly. If required, replace the solenoid.

  4. Clear the fault code: Once the repairs have been made, clear the fault code using a diagnostic tool. This will reset the vehicle's onboard computer and ensure that the issue has been resolved.

It is recommended to consult a professional mechanic or dealership for a thorough diagnosis and repair of the P006F fault code. They will have the necessary tools and expertise to accurately pinpoint the source of the problem and provide a proper solution.


What are the symptoms of the P006F code?

  • Check Engine Light (CEL) or Malfunction Indicator Lamp (MIL) is illuminated
  • Lack of power or reduced engine performance
  • Turbocharger or supercharger may not function properly
  • Vehicle may exhibit poor acceleration or hesitation during acceleration
  • Increased fuel consumption


What causes the P006F code?

The fault code P006F stands for "Turbocharger/Supercharger Boost Control "A" Supply Voltage Circuit High." This code usually indicates an issue with the supply voltage circuit for the turbocharger or supercharger boost control system. Some possible causes for this fault code include:

  1. Faulty boost control solenoid: A malfunctioning boost control solenoid can cause the voltage in the circuit to be too high.

  2. Shorted or open wiring: Any shorted or open wiring in the boost control circuit can cause high voltage readings.

  3. Faulty boost pressure sensor: A defective boost pressure sensor can lead to incorrect voltage readings in the circuit.

  4. ECM/PCM issue: A problem with the Engine Control Module (ECM) or Powertrain Control Module (PCM) can also cause high voltage in the boost control circuit.

It is important to note that diagnosing and repairing this fault code requires advanced diagnostic equipment and technical knowledge. It is recommended to seek assistance from a qualified mechanic or dealership to accurately diagnose and resolve the issue.

Possible Solutions

How to fix P006F?

To fix the P006F fault code on cars, you can follow these steps:

  1. Start by checking the turbocharger/supercharger boost control "A" supply voltage circuit for any visible damage or loose connections.
  2. Inspect the wiring harness and connectors for signs of corrosion, frayed wires, or damaged insulation. Repair or replace any damaged components as necessary.
  3. Clear the fault codes using a OBD-II scanner or diagnostic tool. Take note of any other stored codes that may require attention.
  4. Test the turbocharger/supercharger boost control "A" supply voltage using a multimeter to verify if the voltage is within the manufacturer's specified range. If the voltage is too high, there may be a problem with the voltage regulator or a short circuit.
  5. Inspect the electrical components related to the turbocharger/supercharger boost control system, such as the boost pressure sensor, boost control solenoid, and any related relays. Repair or replace any faulty components as needed.
  6. Reset the fault codes once again and take your car for a test drive to ensure the P006F code does not return. If the code reappears, further diagnosis may be required, and it is recommended to seek professional assistance from a qualified mechanic or a dealership specialized in your car's brand.

Please note that the specific repair steps may vary depending on the make and model of your car. It is always advisable to consult the vehicle's service manual or contact a professional mechanic for accurate diagnosis and repair instructions.
