Default Sensor for Barometer data

Which sensor reports barometer data on a 2007 f150 5,4 l triton?

I believe it's built into the maf, or perhaps the PCM calculates the baro based on ma flow and temperature.

The second option makes no sense for me.
I can't see any relation between air flow, temperature and air pressure?
Are there by other building years separate sensors known?

In other words it approximates the baro reading by calculating using values from the maf reading and the iat reading if I understand correctly.

I mean it already calculates the air "mass" by measuring the voltage required to keep the hot wire/film at a constant temperature, so it's probably not a great leap to also calculate the baro using available info and some assumptions.

Have to ask "Why?" Are you trying to solve a particular problem or is this just curiosity.

What I've observed on Fords in general is that, if they do not have a discrete BARO sensor installed under the hood, is that 1) there's a barometric pressure sensor internal to the PCM, 2) MAP or DPFE sensor is used at startup to measure BARO, or 3) it's calculated based on other inputs. Have no idea as to your specifics at this point in time, haven't dug into it.

Best description I recall reading about what the MAF does.👍
