Barometric Pressure Sensor, whats it do?

[melmount]

Any one have a clue what the Barometric Pressure Sensor does?
just curious, somethings not right with my truck. Want to know what the sensors do.
thx

If I remember right I believe its located under the driver side dash. The purpos of it... its acts as a baseline or refrence for the map sensor. The computer compares the two and comes up with a boost reading. I.E. very essential.

anyone hear of one of these going bad?

As of yet I have not but anything is possible.

Tell me if I'm wrong,someone out here will know,but I believe the barometric pressure sensor would control air/fuel ratio for proper combustion-such as sea level pressures-the higher above sea level,it would be more air than fuel and vise-versa

Exactly, and to do that it has to be compared with the map sensor so it knows it has the right amount of boost for the rpm and such.
