9) Check for each pressure of low side and high side if it is within
shaded range of left graph.
NOTE:
Pressure registered on gauge varies with ambient tem-
perature. Therefore, use left graphs when determining if
pressures are normal or not.
Example:
If each gauge reading is out of specified pressure, correct de-
fective part referring to following Diagnosis Test table.
10) Check inlet port temperature-to-outlet port temperature rela-
tionship using graph at the left.
For example, if evaporator inlet port temperature is 25
C (77
F) and center duct air outlet temperature is 8
C (46.4
F),
their crossing point is within acceptable range as shown in
graph at the left.
11) If crossing point is out of acceptable range, diagnose trouble
referring to following Diagnosis Test table.

AIR CONDITIONING (OPTIONAL)
Gauges should read as follows when ambient tempera-
ture is 30
C.
Pressure on high pressure
gauge (HI):
1.18 – 1.47 MPa
12.0 – 15.0 kg/cm
2
Pressure on high pressure
gauge (LO):
0.2 – 0.3 MPa
2.0 – 3.0 kg/cm
