9000 CSE L4-2290cc 2.3L DOHC Turbo EFI (1995)
High Pressure Sensor / Switch: Specifications
Stage 1:
Allows the compressor to work at temperatures
down to ............................................................................................................................................................................................. +0 °C (32 °F)
Pressure in the system at this temperature
is about .............................................................................................................................................................................................. 2 bar (29 psi)
Stage 2:
For R12 refrigerant starts the engine's electric radiator fan at a pressure
of about .................................................................................................................................................................................. 15 bar (210 psi)
and disconnected
at ............................................................................................................................................................................................ 11 bar (155 psi)
For R134a refrigerant, the fan is started
at ......................................................................................................................................................................................... 16.5 bar (239 psi)
and disconnected
at ......................................................................................................................................................................................... 12.5 bar (181 psi)
Stage 3:
This is a safety feature which breaks the electrical circuit to the compressor if pressure exceeds:
for R12 refrigerant ....................................................................................................................................................................... 27 bar (380 psi)
and reconnected when pressure is
below ................................................................................................................................................................................................ 6 bar (90 psi)
for R134a refrigerant the switch breaks
at .................................................................................................................................................................................................. 30 bar (435 psi)
