TROUBLE DIAGNOSIS
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 spec-
ified pressure is obtained.
Air suction by cooling fan is
insufficient.Insufficient condenser cooling
performance
↓
1. Condenser fins are clogged.
2. Improper fan rotation of cool-
ing fan
●Clean condenser.
●Check and repair cooling
fan as necessary.
●Low-pressure pipe is not
cold.
●When compressor is
stopped high-pressure
value quickly drops by
approximately 196 kPa
(1.96 bar, 2 kg/cm
2 , 28
psi). It then decreases
gradually thereafter.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 each
engine cooling system.
●An area of the low-pres-
sure pipe is colder than
areas near the evaporator
outlet.
●Plates are sometimes cov-
ered with frost.
●Excessive liquid refrigerant
on low-pressure side
●Excessive refrigerant dis-
charge flow
●Expansion valve is open a lit-
tle compared with the specifi-
cation.
↓
1. Improper expansion valve
installation
2. 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.
●Check and repair or replace
malfunctioning parts.
●Check lubricant for contami-
nation.
