Refrigerant Pressure Sensor / Switch: Description and Operation
CIRCUIT DESCRIPTION
The pressure switch sends the appropriate signals to the ECM when the A/C refrigerant pressure drops too low or rises too high. When the ECM receives
these signals, it outputs signals via the ECM to switch OFF the compressor relay and turns the magnetic clutch OFF.
