Can you pull up live engine data on your scan tool and see what the MAP sensor and Intake Air Temperature sensor voltages are at idle. And if possible, I would graph both of these data PIDs to watch for any signal drop out. These 2 sensors have wiring close together at the PCM connector C1 pin 10 is the MAP sensors 5volt Reference, and C1 pin 17 is the IAT sensor Ground.
With the live data on the scan tool, you can monitor these sensor signals much easier than back probing with a multimeter on each.
One thing I would do right away is with the Key On engine Off, unplug the MAP sensor and check each of the 3 wires for 5volts. One wire should have 5volts on it, do the same with the IAT sensor, it needs to unplug to check the 5volt Reference.
The P0113 and P1111 are both for the Intake Air Temp sensor reading -40 degrees for more than 3 seconds, and -40 degrees on a temp sensor is a default temperature reading by the PCM when this sensor's signal is missing.
The P0107 and P1107 are both for the MAP sensors signal reading below 0.1volts for more than 3 seconds. So, these sensors are losing their signals for some reason.
2nd Diagram, the MAP sensors grey wire should be its 5volt Ref, and the IAT sensor Tan wire should be 5volts with the sensor unplugged, Key on engine off.
