I have a radix installed w/ wester tune, so basically stock.. in a 2001 GMC C3, i had issues w/ camshaft position sensor and found the problem but now i have a new problem its P0107 (MAP/BArometric pressure circuit low input) and P0135-P0155 (O2 sensor heater circuit malfunctionn bank 1and 2).. Does anyone here now what caused the code and how to fix it?? any clues to what set it off???
thanks,
mike

 

loose ground?

 

I checked the wires, i'll probably check the map wires later.. anybody else know what could be wrong??

 

When did it start?Has it always been prefect and then one day it set the light?Anything change recently?Someone work on it? someone clean and over oil a K&N?

 

i don't know when it started but i had the camshaft position sensor fail and found the problem about close to a month, it was a wire that had been cut.. then i had the ses reset and a week later ses came on again and both o2 sensors set the ses and had them replaced two weeks ago and the ses didn't reset. i got it diagnosed and now map light is on.. i'm thinking that i spent 200 bucks on o2 for nothing, im thinking that this map is triggering the o2 sensor..
i still have the stock k&n filter from radix..
Oh, sometimes the truck stalls and rpm fluctuates... when this happens and i give it gas it seems to bog, like theres no fuel or something..

 

I checked my GM shop manuals and without the Tech 2 scan tool the only thing you might be able to check for is a 5V reference signal to the MAP. Check for a blown HO2S fuse.
