As you see the two codes are the same
the main issue is the map sensor
P2074-MANIFOLD PRESSURE/THROTTLE POSITION 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.
POSSIBLE CAUSES
à   GOOD TRIP EQUAL TO ZERO
à   VACUUM LEAK
à   HIGH RESISTANCE IN MAP (K7) 5 VOLT SUPPLY CIRCUIT
à   RESISTANCE TO GROUND IN MAP (K7) 5 VOLT SUPPLY CIRCUIT
à   MAP SENSOR
à   HIGH RESISTANCE IN (K1) MAP SIGNAL CIRCUIT
à   RESISTANCE TO GROUND IN (K1) MAP SIGNAL CIRCUIT
à   HIGH RESISTANCE IN (K4) MAP GROUND CIRCUIT
