01 metro, codes p0111 p0113 p0340

just bought an 01 metro, it is throwing 3 codes: p0111 p0113 and p0340. 340 is the cam sensor, 111 and 113 are the IAT sensor. the car runs decent, has a slight miss. starts fine cold, takes a few tries when warm.

i was wondering if one problem may be causing the other code, it's possible that i might actually have a problem with both, but in my experience it's usually one code that causes another to come on. i am leaning toward the IAT being the actual code and the cam sensor code being the side effect. will replace both if necessary but obviously i just want to replace one of the two if that will fix the problem, and wondering if anyone else here has had a similar problem or can say with a bit more certainty which codes to concentrate on first before i go out buying a bunch of parts.

thanks

edit:

tested the intake air temp sensor by submersing in water, heating, and watching resistance drop, seems to be within range.

anyway to test the cam sensor? i have been searching but cannot find a test procedure.
