P006D Barometric Pressure - Turbocharger/Supercharger Inlet Pressure Correlation Bank 1
The relationship between barometric pressure and turbo inlet pressure (bank 1) is implausible — at engine off the two should match. Indicates an inlet sensor or barometric sensor fault.
Is it safe to drive with P006D?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
