These sensors screw out..
Not come across any info explaining how to really test them,
Its usually done with Diagnostics, if certain the AC is full of gas, and still reading little or no pressure, then it points to the sensor ..

Its got a one way valve system on the pipe work on these @LvR, soon as its undone no gas worth talking about will come out..

Your Car.
the unknown fault = Thermoplungers
Your AC, this if,, controlled by engine ECU,,, and you have other faults..

AC "IS" disabled

Cannot make out what ECU OP has fitted, Just EDC16.. .
so not sure if short to battery is from the pressure sensor , but something back of my mind is saying this is the fault the ECU logs to stop it working if other faults are present
would think AC guys have bypassed this sensor by applying power to the pump, to get the system to work ( Naughty people )..

Yours Climate Control ..
Would go have the Aircon system checked now multiplug is on, and see what codes will clear..
Themoplungers, though not sure if part of AC or Ecu as regards stopping AC, dont think they are,, would leave alone.
As you can not not buy these separately , ( You have 4 , look like glowplugs )

If a fault detected in the ECU, and AC controlled by ECU, then there wont be any voltage to talk about AC, is disabled..

Or the one @LvR really wants is the 4 alphanumeric just below this VIN, this is more accurate, as Renault dont always play fair
