Need some help on DTC's

[Cknox121]

P2262- Turbo Boost Pressure Not Detected- Mechanical
P0069Manifold Absolute-Pressure-Barometric Pressure Correlation
P006B Unknown DTC

I check EBP sensor, cleaned and reinstalled...wasn't even that dirty.

Where should I start? I'm not a trouble shooter by any means.

Thanks for the help?

I'd be looking at the MAP sensor
