Question about Cars & Trucks
Thats alot of codes, and most likely your vehicle has multiple problems. an 04 explorer gets it baromnetric pressure signal via the MASS-AIR sensor near the air cleaner. If there is a problem with that sensor, the intake air, barometric pressure, engine load calculation and main fuel calculations will all be affected or disabled causing the vehicle to run poorly or possibly not at all. Id recommend testing it using fairly advanced equipment and procedures. an OBD2 capable scantool that has datastream and snapshot ability at the very least , coupled with a volumetric efficiency calculator will tell you how well the MAF is doing its job if it is working at all. a labscope or good multimeter can also be used but they are less exact.
Depending on the type of fault and the fuel trim results, the entire problem could be in the Mass Air sensor circuit or its air flow sealing.
The EGR code is a seperate system. worst case if the EGR valve is stuck wide open it could also be a contributing factor to poor idling and MAF sensor codes and r=terrible mileage, however the EGR uses a sensor called Delta Pressure Feedback-EGR. (DPFE for short). This sensor measures the flow of the EGR by checking the differences in 2 different hoses coming off the EGR feed pipe; If either hose has a problem, you get EGR codes, if the valve has a proiblem you get codes, or if the DPFE has a problem, yes, you get codes. the DPFE sensors fail OFTEN! But I would still always verfify function using a scantool with enhanced ford datastream and manual activation ability before recommending a part.

Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor P0106 code is set when there is a problematic or erratic performance in the voltage signal to the PCM.
