Default 2003 Ram 2500 5.7l

Hello all,
Let me start this out by stating I have a 2003 Ram 2500 5.7l hemi. Quad Cab. Long story short my truck caught on fire. I have replaced everything that got burnt. Right now my code reader is giving me the following Codes: P0129, P0138, P2127, P2106 These are the codes from the truck. I also have these Codes from a actual scanner: P0129, P0138. I'm not too worried about the 02 sensor codes. I replaced the MAP Sensor already and code still pops up. The lightning bolt / ETC light is blinking while driving. I had to replace the throttle body do to the fire. It didn't come from the exact truck but same one. I tried to reset the new throttle body to the truck using the manual but doesn't seem to help at all. Can the accelerator pedal position switch (APPS) cause these problems? Any way to test the APPS that located under the battery? Does anyone have locations to where all the engine Ground straps are located at? Or could the throttle body just be a bad one and replacing that will fix my problems? Not trying to throw any more money just buying parts. Thanks too all that can help me out..
