The P006F: Turbocharger/Supercharger Boost Control ‘A’ Supply Voltage High refers to a problem with the supply voltage to the turbocharger or supercharger boost control circuit being too high. This issue can be caused by a faulty boost control solenoid, excessively high voltage supply, wiring or connection issues, or a failure in the Powertrain Control Module (PCM). In simple terms, when this code appears, it indicates that the system responsible for managing the boost pressure in your engine may be receiving too much voltage, which can negatively impact engine performance.

P006F Meaning
The P006F: Turbocharger/Supercharger Boost Control ‘A’ Supply Voltage High code indicates that there is a problem with the voltage supply to the boost control system in your engine being too high. This can result from a defective boost control solenoid, overly high voltage, or issues with wiring or connections. If this system is receiving too much voltage, it can cause the engine to overboost, leading to potential performance issues and possible damage to the engine.
Step-by-step diagnostic guide
Follow the outline procedure to diagnose this DTC by eliminating possible causes one by one.
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check if there are any other related codes present. These might give additional clues about the problem. | OBD-II Scanner |
| Test the Boost Control Solenoid | Test the boost control solenoid for correct operation, ensuring it is functioning properly. | Multimeter, Manufacturer’s Specifications |
| Measure Supply Voltage | Measure the supply voltage to the boost control circuit and compare it to the manufacturer’s specifications to ensure it is not too high. | Multimeter, Manufacturer’s Specifications |
| Inspect Wiring and Connections | Carefully inspect the wiring and connections related to the boost control circuit for any signs of damage, corrosion, or loose connections. | Flashlight, Multimeter |
| Repair or Replace Faulty Components | If any components, wiring, or connections are found to be faulty, repair or replace them as necessary. Ensure that all connections are secure and free from corrosion. | Wire Strippers, Electrical Tape, Replacement Wires/Connectors |
| Clear the Code and Test Drive | After repairs, clear the P006F code using the OBD-II scanner. Take the vehicle for a test drive to ensure the issue is resolved and the code does not return. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P006F code has not reappeared. If the code returns, further diagnosis may be required. | OBD-II Scanner |
