Question about certain part

[WhitePantherKnight]

Hello everyone, new to the forum and really enjoying reading some of the posts so far.
Quick question, What does the front suspension height sensor do or control?
Basically I work on wagons that have air bags, so I can say that those sensors control the ride heights, but obviously the phev don't have air, which I'm toying with a idea of doing on my vehicle, but that another time for now.
