P006F Turbocharger/Supercharger Boost Control A Supply Voltage Circuit High
Supply voltage to boost control actuator A above expected range. Same as P005F but on actuator A. Boost control tracks commanded vs. actual manifold pressure; persistent deviation means wastegate, vanes, hose or actuator are not delivering the requested pressure.
Is it safe to drive with P006F?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelyAlternator regulator failed
- Less likelyConnector pins corroded - high contact resistance
