Trouble Diagnosis For Unusual PressureINFOID:0000000009463923
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 pres sure table) since the standard (usual) pressure, how-
ever, differs from vehicle to vehicle.
Symptom TableINFOID:0000000009463924
Gauge indication Refrigerant cycle Probable cause Corrective action
Both high and low pressure sides
are too high. The pressure returns to nor-
mal soon after sprinkling wa-
ter on condenser. Overfilled refrigerant. Collect all refrigerant, evacuate
refrigerant cycle again, and
then refill it with the specified
amount of refrigerant.
Air flow to condenser is insuf-
ficient. Insufficient condenser cooling
performance.
• Poor fan rotation of radiator and condenser.
• Improper installation of air
guide.
• Clogged or dirty condenser fins. • Repair or replace malfunc-
tioning parts.
• Clean and repair condenser
fins.
When compressor is stopped,
a high-pressure reading
quickly drops by approximate-
ly 196 kPa (2 kg/cm
2, 28 psi).
It then gradually decreases. Air mixed in refrigerant cycle.
Collect all refrigerant, evacuate
refrigerant cycle again, and
then refill it with the specified
amount of refrigerant.
• Low-pressure pipe is cooler than the outlet of evapora-
tor.
• Low-pressure pipe is frost- ed. Expansion valve opened too
much (excessive flow of refrig-
erant). Replace expansion valve.
High-pressure side is excessively
high and low-pressure side is too
low.
High-pressure pipe and upper
side of condenser become
hot, however, liquid tank does
not become so hot. Clogged or crushed high-pres-
sure pipe located between
compressor and condenser. Repair or replace the malfunc-
tioning parts.
High-pressure side is too low and
low-pressure side is too high. • The readings of both sides
become equal soon after
compressor operation
stops.
• There is no temperature dif- ference between high- and
low-pressure sides. Malfunction in compressor sys-
tem (insufficient compressor
pressure operation).
• Damage or breakage of
valve.
• Malfunctioning gaskets. Replace compressor.
