What P006F means
"Boost control A" is the electrically driven actuator the engine control module uses to set boost pressure, for example a wastegate solenoid, the control valve of variable turbine vanes or an electric actuator. Some engines supply it through two driver stages in the control module: a high side that switches the supply voltage and a low side that switches ground. The low side is covered by P0045 to P0048; this code concerns the high side. P006F is set when the voltage on the supply circuit is too high, typically because the supply wire is shorted to battery voltage, so the control module can no longer switch the actuator off. Without supply the actuator stays in its rest position, which on most engines means low boost and reduced power.
P006F at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of P006F
- Check engine light on
- Loss of power or reduced power mode
- Weak acceleration, noticeable turbo lag
Common causes of P006F
- Most likelySupply wire shorted to battery voltage
- PossibleWater or corrosion in the connector
- PossibleInternal fault in the actuator
- Less likelyHigh-side driver in the engine control module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P006F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 6F | The exact fault in that area. |
What to do next
- Note P006F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P006F
What does P006F mean?
P006F means "Turbocharger/Supercharger Boost Control A Supply Voltage Circuit High". "Boost control A" is the electrically driven actuator the engine control module uses to set boost pressure, for example a wastegate solenoid, the control valve of variable turbine vanes or an electric actuator. It is a generic code, so it means the same on every make.
Is it safe to drive with P006F?
Drive gently and only to a workshop. With P006F the car can go into limp mode (reduced power) to protect itself.
Will P006F fail an emissions test?
Yes, it can. P006F is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P006F to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P006F clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
