have a look here:

P0113 is intake temp sensor hight input:
you have a hight voltage on this input (1/D1 1/E4 of the ecu connector). 
As there is certainly a pull up resistor
on this input, you most probably have it hight impedance (disconnected). 
A normal sensor should
(depending on the temp) show between 6.1kOhm and 1.6kOhm. Don't check 
the impedance w/o disconnecting the ecu.
You could damage the input buffer. Check directly on the sensor, after 
disconnecting it and check for continuity of wires,
ecu disconnected. Be cautious and carefull. I would suggestion asking 
help from a fellow w/ some electronic knowledge
if you'r not comfy w/ the manip.

P0105 is Manifold Absolute Pressure/Barometric Pressure Circuit 
Malfunction. This is the sensor located
inside the ECU (CPU). This one doesn't appear in the workshop manual. I 
don't really imagine this one failing
as it is directly in the ECU. I had a look a while ago in the datasheet 
of the maker indicating that most of the time
it's soldered on the pcb. That's the way they are conceived. I would 
suggest the hose is missing or disconnected
or leaking.
