Multi-Function Thermal Sensor / Switch: Description and Operation
A/C PRESSURE TRANSDUCER
The A/C pressure transducer communicates the compressor discharge pressure to the PCM. The PCM will interrupt A/C compressor operation in the
event that the A/C pressure transducer indicates excessively high system discharge pressures. It is also used to sense low charge conditions. If the
pressure is below a predetermined value for a given ambient temperature, the PCM will not allow the clutch to engage.
