P006E Turbocharger/Supercharger Boost Control A Supply Voltage Circuit Low
Supply voltage to boost control actuator A below expected range. Same as P005E 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 P006E?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelySupply fuse blown or relay failed
- Less likelyConnector pins corroded - high contact resistance
