The linear pressure sensor of the refrigerant fluid fitted on the condenser supplies a voltage proportional to the pressure in the air conditioning circuit and transmits this information to the BSI on the CAN IS network.
Wow!
All now clear though: both coolant temp and refrigerant pressure are being sensed.
