Refrigerant Pressure Sensor / Switch: Description and Operation
A/C Pressure Sensor
A/C Pressure Transducer
The A/C pressure transducer is mounted on a Schrader valve-type fitting on the A/C manifold and tube.
-
A valve depressor, located inside the threaded end of the A/C pressure transducer, presses in on the Schrader valve stem.
-
This allows the compressor discharge pressure to be monitored by the Powertrain Control Module (PCM).
-
The A/C pressure transducer provides a voltage signal that is proportional to the A/C compressor discharge pressure.
-
The PCM uses this information for A/C clutch control, cooling fan control and idle speed control.
-
It is not necessary to discharge the refrigerant system to remove the A/C pressure transducer.
