3.2TL TYPE S V6-3.2L SOHC (2002)
Refrigerant Pressure Sensor / Switch: Description and Operation
A/C Pressure Switch, Type S
A/C Pressure Switch (Type S Model)
The A/C pressure switch consists of a High-Low pressure switch (A/C pressure switch A) and a Middle pressure switch (A/C pressure switch B).
-
High-Low pressure switch
If the refrigerant pressure becomes too high (due to blockage), or too low (due to leakage), the A/C pressure switch sends a signal to the PCM to
prevent the compressor from operating.
-
Middle pressure switch
If the refrigerant pressure goes above or below 1,520 kPa (15.5 kgf/sq.cm, 220 psi), the A/C pressure switch sends a signal to the climate control
unit to change the speed of the condenser fan and radiator fan (High-Low).
