PCM Barometric Pressure
2005, F150, 5.4L. From what sensor does the PCM get Barometric Pressure and Outside Temperature? With a scanner, mine shows a pressure of 27.1 "hg, and 10 deg.F, when actual is ~30.0 "hg and 45 deg. F. Intake Air Temp. is correct, but this doesn't the programming use barometric pressure and MAP for it's fueling plan?
