a/c problems 850 1994

Hello everyone

I have some problems with my a/c. It works fine, but i guess the compressor
works all the time. I dont think its the temperature problem cos i tried it in the cold days and it also does not cycle. The only way to turn the compressor off is to turn it off by the a/c switch. The engine diagnostic shows a code
2 - 2 - 5 which represents a fault in air pressure sensor ( i guess this is
the one below the diagnostic unit close to the compressor, which has 3 wires )
So my qustion is how can i check if its the sensor ( maybe its another one ?)
as it is connected to the high pressure refrigerent how to change ?

and also i have another query with another sensor of a/c dont know its name
it has 2 wires ( close to the windshield.


best regards

Marek
