Refrigerant Pressure Sensor / Switch: Description and Operation
How the Circuit Works
The climate control unit controls the blower controls, air delivery, and A/C compressor controls automatically. With the ignition switch in ON (II),
battery voltage is supplied through fuse 14. The control unit is grounded at G402.
A/C Pressure Switch
The A/C pressure switch is located in the condenser outlet line where refrigerant is in a high temperature/high pressure liquid state. The switch will sense
abnormally high or low pressure, and open the circuit. This removes ground from the ECM/PCM, and turns off the compressor.
