P006F
Turbocharger/Supercharger Boost Control A Supply Voltage Circuit High
Turbo / boost control
Generic OBD-II
High
What it means
P006F means the voltage supplied to the "A" boost control device (solenoid/actuator) is higher than expected. It usually points to a short-to-power in the supply wiring, a charging-system overvoltage, or a failed actuator/module — not a misfire or knock-sensor issue, despite how some databases label it. Boost control is affected, so the engine may fall into reduced-power mode.
High
Can I keep driving? Yes, with possible reduced power — a boost-control supply-voltage fault can trigger limp mode; drive gently until repaired.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced boost and power
- Possible reduced-power / limp mode
- Sluggish acceleration
Common causes
Most likely first
- Short-to-voltage in the boost control supply circuitLikely
- Wiring or connector fault at the boost control solenoid / actuatorCommon
- Charging-system overvoltage raising the supply referenceCommon
- Failed boost control actuator or moduleLess often
- ECM supply-circuit faultLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data to confirm the operating conditions.
- Check charging-system voltage — an overcharging alternator can push the supply high.
- Inspect the boost control actuator connector and supply wiring for a short-to-power.
- Measure the supply voltage at the actuator connector against spec.
- Replace the actuator/solenoid or module if faulty; suspect the ECM only after wiring is verified.
FAQ
Quick answers
Is it safe to drive with P006F?+
You can drive gently, but boost is limited and the car may enter limp mode. Have it diagnosed soon, and check the charging system, which can be the root cause.
Can I just clear P006F?+
It returns until the high supply-voltage condition is corrected.
