Default Help with Codes

I need some help in determining what is causing the following codes so I can fix them. These are now showing up after I had my car worked a bit and it looks like the shop I took it too will not stand behind therir work( at least right now ).

This is on a C5.

P0522 - Engine Oil Pressure Sensor Circuit Low Voltage
P0705 - Transmission Range Sensor Circuit (PRNDL Input)
P1220 - Throttle Position Sensor 2 Ckt

P1516 - Commanded vs Actual TP Performance
P1518 - PCM To TAC Module Serial Data Circuit
P1635 - Tire/Axle Out of Acceptable Range

Does anyone know what might cause these and/or things I can do to correct them? I have not done too much so far, other than the obvious things like checking all the cabling to the throttle body and such.

TIA,
Keith
