I don't know about your car, but on the 124/103 there are two sensors. One is in the head and it activates the fans to run on high speed based on temperature. The other is on the drier and activates the fans to run on low speed.

Any AC sensor on the drier which commands the fans to run is a pressure switch.

Of course, higher pressure equals higher temperature so in the big picture the effect is the same.
