Codes translate as...
P2074 = Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Higher Load.
P2047 = Reductant Injection Valve Circuit/Open Bank 1 Unit 1
The first is the air intake system and the second is the fuel delivery system.

A P2074 DTC is the Manifold Absolute Pressure/Mass Air Flow-Throttle Position Correlation at Higher Load. I wuold start with this one first because it came up first and there may be more than one problem.Good Luck.
CODE PO120 - TP SENSOR 1 SIGNAL RANGE PERFORMANCE. CODE P1516 - TAC MODULE THROTTLE ACTUATOR POSITION PERFORMANCE. CODE P2135 - THROTTLE POSITION SENSOR 1 - 2 CORRELATION ERROR. THIS IS A DEALERSHIP FIX YOU HAVE PROBLEMS OR FAULTS IN THE THROTTLE POSITION SENSOR.
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input Have u had any work done on the engine lately or anything done under the hood? looks like something in the area of the MAF sensor is disconnected or the sensor itself is disconnected, all the codes are related.
P2074-manifold Pressure/throttle Position Correlation
CORRELATION - HIGH FLOW/VACUUM LEAK
When Monitored: Engine Running, during all drive modes.
Set Condition: If vacuum drops below 1.5 Hg with engine RPM greater than 2000 RPM
at closed throttle.
