7. To complete the charts:
• Mark the delivery temperature along the vertical line.
• Mark the intake temperature (ambient air temperature) along the bottom line.
• Draw a line straight up from the air temperature to the humidity.
• Mark a point 10 % above and 10 % below the humidity level.
• From each point, draw a horizontal line across the delivery temperature.
• The delivery temperature should fall between the two lines.
• Complete the low-side pressure test and high-side pressure test in the same way.
• Any measurements outside the line may indicate the need for further inspection.
Example
Intake temperature (dry):
86 °F (30 °C) Humidity level 70 %
Intake temperature (wet):
77.9 °F (25.5 °C)
Intake pressure:
281 kPa (2.9 kgf/cm ) (40.8 psi)
Delivery temperature:
56.1 °F (13.4 °C)
Delivery pressure:
1,707 kPa (17.4 kgf/cm ) (247.5 psi)
Results:
Within normal range

Discharge (high)
pressure
abnormally high
After stopping A/C compressor, pressure
drops to about 196 kPa (2.0 kgf/cm , 28 psi)
quickly, and then falls gradually.
Air in system
Recover, evacuate (see page 21-63), and
recharge with specified amount
(see page 21-64).
Reduced or no airflow through A/C
condenser.
Clogged A/C condenser or
radiator fins
A/C condenser or radiator
fan not working properly
Clean.
Check voltage and fan rpm.
Check fan direction.
Line to A/C condenser is excessively hot.
Restricted flow of refrigerant
in system
Replace restricted lines.
Discharge
pressure
abnormally low
High and low-pressures are balanced soon
after stopping A/C compressor. Low side is
higher than normal.
Faulty A/C compressor
discharge valve
Faulty A/C compressor seal
Replace the A/C compressor.
Outlet of expansion valve is not frosted,
low-pressure gauge indicates vacuum.
Faulty expansion valve
Moisture in system
Replace.
Recover, evacuate, and recharge with
specified amount.
Suction (low)
pressure
abnormally low
Expansion valve is not frosted, and low-
pressure line is not cold. Low-pressure
gauge indicates vacuum.
Frozen expansion valve
(Moisture in system)
Faulty expansion valve
Recover, evacuate, and recharge with
specified amount.
Replace the expansion valve.
Discharge temperature is low, and the
airflow from vents is restricted.
Frozen evaporator
Run the fan with A/C compressor off,
then check evaporator temperature
sensor.
Expansion valve is frosted.
Clogged expansion valve
Clean or replace.
Receiver/dryer outlet is cool, and inlet is
warm (should be warm during operation).
Clogged receiver/dryer
Replace.
Suction pressure
abnormally high
Low-pressure hose and check joint are
cooler than the temperature around
evaporator.
Expansion valve open too
long
Repair or replace.
Suction pressure is lowered when A/C
condenser is cooled by water.
Excessive refrigerant in
system
Recover, evacuate, and recharge with
specified amount.
High and low-pressures are equalized as
soon as the A/C compressor is stopped,
and both gauges fluctuate while running.
Faulty gasket
Faulty high-pressure valve
Foreign particle stuck in
high-pressure valve
Replace the A/C compressor.
Suction and
discharge
pressures
abnormally high
Reduced airflow through A/C condenser.
Clogged A/C condenser or
radiator fins
A/C condenser or radiator
fan not working properly
Clean.
Check voltage and fan rpm.
Check fan direction.
Suction and
discharge
pressures
abnormally low
Low-pressure hose and metal end areas
are cooler than evaporator.
Clogged or kinked low-
pressure hose parts
Repair or replace.
Temperature around expansion valve is
too low compared with that around
receiver/dryer.
Clogged high-pressure line
Repair or replace.
Refrigerant leaks
A/C compressor clutch is dirty.
A/C compressor shaft seal
leaking
Replace the A/C compressor.
A/C compressor bolt(s) are dirty.
Leaking around bolt(s)
Tighten bolt(s) or replace A/C
compressor.
A/C compressor gasket is wet with oil.
Gasket leaking
Replace the A/C compressor.
