Multiple codes triggered, possible short circuit? Vacuum issue?

Hi folks

The following codes have all triggered at once:

P2009 Intake Manifold Runner Control Circuit Low Bank 1
P0112 Intake Air Temperature Circuit Low Input
P0100 Mass Air Flow (MAF) Circuit Malfunction
P0102 Mass air flow (MAF) sensor/volume air flow (VAF) sensor low input
P1102 Mass Air Flow Sensor In Range But Lower Than Expected
P0243 Turbocharger Wastegate Solenoid A Malfunction

Could it be a vacuum issue? I've check all hoses visually and cannot see any cracks, they all appear to be in good condition. None appear to be dislodged.

Any ideas what it could be or anything I can do to test?
