System Description INFOID:0000000004232263
REFRIGERANT CYCLE
Refrigerant Flow
The refrigerant flows from the compressor, through the condenser with liquid tank, through the evaporator, and
back to the compressor. The refrigerant evaporation in the evaporator is controlled by an externally equalized
expansion valve, located inside the evaporator case.
Freeze Protection
To prevent evaporator from freezing up, the evaporator air temperature is monitored, and the voltage signal to
the A/C amp. makes the A/C relay go OFF and stop the compressor.
REFRIGERANT SYSTEM PROTECTION
Refrigerant Pressure Sensor
The refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure sen-
sor, located on the liquid tank. The refrigerant pressure sensor detects the pressure inside the refrigerant line
and sends the voltage signal to the ECM if the system pressure rises above, or falls below the specifications.
ECM makes the A/C relay go OFF and stops the compressor when pressure on the high-pressure side
detected by refrigerant pressure sensor is over approximately 3,120 kPa (31.20 bar, 31.8 kg/cm2, 452 psi), or
below approximately 140 kPa (1.40 bar, 1.4 kg/cm2, 20 psi).
Pressure Relief Valve
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
The release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere
when the pressure of refrigerant in the system increases to an unusual level [more than 3.6 MPa (36 bar, 36.7
kg/cm2, 522 psi)].

Component Description INFOID:0000000004232265
Component Description
Compressor Intakes, compresses, and discharges refrigerant, to circulate refrigerant inside the refrigerant cycle.
Condenser Cools refrigerant discharged from compressor, and transforms it to liquid refrigerant.
Liquid tank Eliminates foreign matter in refrigerant, and stores temporarily liquid refrigerant.
Refer to EC-437, "Description" (FOR CALIFORNIA), EC-873, "Description" [FOR USA (FEDERAL)
Refrigerant pressure sensor
AND CANADA] or EC-1230, "Description" (FOR MEXICO).
Transforms high-pressure liquid refrigerant to mist form low-pressure liquid refrigerant by drawing

The mist form liquid refrigerant transforms to gas by evaporation by the air conveyed from blower

SYMPTOM DIAGNOSIS A
REFRIGERATION SYSTEM SYMPTOMS
Trouble Diagnosis For Unusual Pressure INFOID:0000000004232266
B
Diagnose using a manifold gauge whenever system's high and/or low side pressure(s) is/are unusual. The
marker above the gauge scale in the following tables indicates the standard (usual) pressure range. Refer to
above table (Ambient air temperature-to-operating pressure table) since the standard (usual) pressure, how- C
ever, differs from vehicle to vehicle.
