TROUBLE DIAGNOSES FOR UNUSUAL PRESSURE
Whenever system¢s high and/or low side pressure is unusual, diagnose using a manifold gauge. The marker
above the gauge scale in the following tables indicates the standard (usual) pressure range. Since the stan-
dard (usual) pressure, however, differs from vehicle to vehicle, refer to above table (Ambient air temperature-
to-operating pressure table).
Both High- and Low-pressure Sides are Too High
High-pressure Side is Too High and Low-pressure Side is Too Low
Gauge indication Refrigerant cycle Probable cause Corrective action
Both high- and low-pressure sides
are too high.Pressure is reduced soon
after water is splashed on
condenser.Excessive refrigerant charge
in refrigeration cycleReduce refrigerant until speci-
fied pressure is obtained.
Air suction by cooling fan is
insufficient.Insufficient condenser cooling
performance
¯
1. Condenser fins are clogged.
2. Improper fan rotation of
cooling fan
lClean condenser.
lCheck and repair cooling fan
if necessary.
lLow-pressure pipe is not
cold.
lWhen compressor is
stopped high-pressure
value quickly drops by
approximately 196 kPa (2
kg/cm
2, 28 psi). It then
decreases gradually there-
after.Poor heat exchange in con-
denser
(After compressor operation
stops, high-pressure
decreases too slowly.)
¯
Air in refrigeration cycleEvacuate repeatedly and
recharge system.
Engine tends to overheat.Engine cooling systems mal-
function.Check and repair engine cool-
ing system.
lAn area of the low-pres-
sure pipe is colder than
areas near the evaporator
outlet.
lPlates are sometimes cov-
ered with frost.
lExcessive liquid refrigerant
on low-pressure side
lExcessive refrigerant dis-
charge flow
lExpansion valve is open a
little compared with the
specification.
¯
Improper expansion valve
adjustmentReplace expansion valve.
AC359A
Gauge indication Refrigerant cycle Probable cause Corrective action
High-pressure side is too high and
low-pressure side is too low.
Upper side of condenser and
high-pressure side are hot,
however, liquid tank is not so
hot.High-pressure tube or parts
located between compressor
and condenser are clogged or
crushed.
lCheck and repair or replace
malfunctioning parts.
lCheck lubricant for contami-
nation.

ATC-98
TROUBLE DIAGNOSIS
High-pressure Side is Too Low and Low-pressure Side is Too High
Both High- and Low-pressure Sides are Too Low
Gauge indication Refrigerant cycle Probable cause Corrective action
High-pressure side is too low and
low-pressure side is too high.High- and low-pressure sides
become equal soon after com-
pressor operation stops.Compressor pressure opera-
tion is improper.
¯
Damaged inside compressor
packings.Replace compressor.
No temperature difference
between high- and low-pres-
sure sides.Compressor pressure opera-
tion is improper.
¯
Damaged inside compressor
packings.Replace compressor.
AC356A
Gauge indication Refrigerant cycle Probable cause Corrective action
Both high- and low-pressure sides
are too low.
lThere is a big temperature
difference between liquit
tand outlet and inlet. Outlet
temperature is extremely
low.
lLiquid tank inlet and expan-
sion valve are frosted.Liquid tank inside is slightly
clogged.
lReplace liquid tank.
lCheck lubricant for contami-
nation.
lTemperature of expansion
valve inlet is extremely low
as compared with areas
near liquid tank.
lExpansion valve inlet may
be frosted.
lTemperature difference
occurs somewhere in high-
pressure side.High-pressure pipe located
between liquit tank and expan-
sion valve is clogged.
lCheck and repair malfunc-
tioning parts.
lCheck lubricant for contami-
nation.
Expansion valve and liquid
tank are warm or only cool
when touched.Low refrigerant charge.
¯
Leaking fittings or compo-
nents.Check refrigerant system for
leaks. Refer toATC-150,
"Checking for Refrigerant
Leaks".
There is a big temperature dif-
ference between expansion
valve inlet and outlet while the
valve itself is frosted.Expansion valve closes a little
compared with the specifica-
tion.
¯
1. Improper expansion valve
adjustment.
2. Malfunctioning expansion
valve.
3. Outlet and inlet may be
clogged.
lRemove foreign particles by
using compressed air.
lCheck lubricant for contami-
nation.
An area of the low-pressure
pipe is colder than areas near
the evaporator outlet.Low-pressure pipe is clogged
or crushed.
lCheck and repair malfunc-
tioning parts.
lCheck lubricant for contami-
nation.
Air flow volume is too low. Evaporator is frozen.
lCheck intake sensor circuit.
Refer toAT C - 11 4 , "
Intake
Sensor Circuit".
lReplace compressor.
lRepair evaporator fins.
lReplace evaporator.
lRefer toAT C - 8 0 , "Blower
Motor Circuit".
