hi

i scanned and noticed these codes. i unplugged the icp sensor and the truck defaulted to 700 or so. couldn't really tell much difference in the way the truck ran but since sensor was off the doner engine and old style...i replaced it with a BW.

tonight, i scanned again with AE and codes are back. i let the truck sit for 6 hrs in very cold temps and this time scanned with KOEO for icp and got a reading of 108psi..fluctuating ever so slightly.

i drove the truck home, it seemed to run good and scanned again once in drive way.KOEO, but this time got "0" for a reading.

is this icp called a biased reading and could it be affected by engine temp?

if this is the infamous biased icp , what do i do about it ?
