codes.. voltage too low???

check engine light came on last night. Checked them out this morning and got these.
P0500-no vehicle speed sensor signal
P1693-companion code
P0237-Map sensor voltage too low
P0236-turbo/super charger boost sensor A circuit range/performance
P0122- Accelerator Pedal Position sensor signal voltage too low

On the P0500 my speed O is broke and i understand the P1693 kicks off of another code but don't know what i should do about the Last 3 codes. Has anybody had these same codes ever thrown and if so how you fixed them.

Actually, in my FSM, P0236 reads "MAP sensor too high too long" which would indicate reading higher than stock boost pressures. I'd clear those codes and pull the Comp box to see if they come back. Might be something wrong with the boost fooler in the Comp.

I'm having the same problem with my edge chip. I got the 0236 as well as I was getting a real rough idle, I mean bad. since turning it off no problems. Edge customer service sucks.

when 0237 came on in my truck it was because my comp had come loose at one of the fittings. my 0236 is on cause my map is unplugged but i have and 0500 but dont have any problems.
