    AC Pressure (pressure) channel inop

    This is a weird one. 2006 Envoy E40. AC Pressure (pressure) channel is always stuck at 184.9 psi (or 1,275 kPa if units are changed), but AC Pressure (volts) reads fine. Fan % responds to changes in (volts) like it should. Anybody else have this happen or just me? Yes I've removed the channel, repolled, re-added channel with no change.

    Tech2 reads it just fine.



    I would just make a math parameter to convert it as a workaround but it's not linear, and I don't have a clue how to make it do that!

    Code:
    V		P		factor
    1.22		 728		596.7213114754098
