Actually, I should make a correction as sometimes my brain lags behind in the "recall mode": a PCM usually reads in KPA (kilo pascals absolute) on the tables vice BAR. It still all equates out the same as it reads the absolute value (ie; stars at zero atmosphere).
OEMs simply rate the sensors in BAR.
It all works out the same as the zero mark is the same whether you're talking KPA, PSIA or Bar. For our purposes, they're just different measures of the same pressure. It's just most calibrations work in metric vice imperial measures.
Yup, even US manufactured vehicles.....
