There are a couple things I recommend that you take the time to understand here.
Diagnostic Test Code (DTC) P0105 is defined by SAE J2012 as "Manifold Absolute Pressure/Barometric Pressure Circuit"
(DTC) P0110 is defined as "Intake Air Temperature Sensor 1 Circuit"
The first thing is that Diagnostic Test Codes (DTCs) commonly referred to as "fault codes", NEVER tell you what parts to replace. These codes are designed to point the auto repair technician to the proper diagnostic testing routine in order to pinpoint the actual cause of the failure. If you do not have access to the diagnostic test routines published by the vehicle manufacturer for the purpose of diagnosing these faults, as well as the proper equipment required to perform the steps in the diagnostic routines, you may be in for an expensive "parts-replacing-no-joy-ride". However, spend your time and money as you wish.
The next thing is that the ENTIRE code definition needs to be taken into consideration. Please note that these are CIRCUIT codes. A sensor cannot function any better than the circuits that connect it to the rest of the engine control system. The circuits to these sensors must be properly tested in order to determine the exact CAUSE of the DTCs setting. - or as mentioned above, you can just replace all the parts associated with these fault codes and hope you get it right.
Another little piece of information you might find helpful is that both of these sensors share the same reference voltage from the engine computer. Fixing ONE of them has a pretty good chance of fixing BOTH of them. Then again, there might be two seperate problems.
However, you will have no way of knowing if it is one or both and if it is only one, then WHICH one actually needs to be fixed without proper diagnosis.
With all that said:
The MAP/BARO sensor is located at the left rear of the engine compartment, near the brake fluid reservoir.
The IAT sensor is located at the left front of the engine compartment, in the air intake duct near the battery

there is two sensors that those code refer too. The map sensor, and the iat sensor. and both would have an effect on gas mileage. Both sensors would just make the car run a rich mixture.

Something must be drawing the battry flat. Probably something you can't see. Start by removeing glovebox light & boot light & see if the current drain stops. If it does one of those lights are staying on.
