2004 NISSAN TERRANO oil pressure

Gauge indicationRefrigerant cycleProbable causeCorrective action
High-pressure side is too high
and low-pressure side is too low.
AC360A
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.I
Check and repair or replace
malfunctioning parts.
I Check compressor oil for
contamination.
High-pressure side is too low
and low-pressure side is too
high.
AC356A
High- and low-pressure sides
become equal soon after com-
pressor operation stops. Compressor pressure opera-
tion is improper.
"
Damages inside compressor
packings Replace compressor.
No temperature difference
between high- and low-pres-
sure sides Compressor discharge capac-
ity does not change. (Com-
pressor stroke is set at maxi-
mum.)Replace compressor.
Both high- and low-pressure
sides are too low.
AC353A
I There is a big temperature
difference between liquid
tank outlet and inlet. Outlet
temperature is extremely
low.
I Liquid tank inlet and expan-
sion valve are frosted. Liquid tank inside is clogged a
little.
I
Replace liquid tank
I Check compressor oil for
contamination.
I Temperature of expansion
valve inlet is extremely low
as compared with areas near
liquid tank.
I Expansion valve inlet may
be frosted.
I Temperature difference
occurs somewhere in high-
pressure side High-pressure pipe located
between liquid tank and
expansion valve is clogged.
I
Check and repair malfunc-
tioning parts.
I Check compressor oil for
contamination.

Areas near low-pressure pipe
connection and service valve
are extremely cold as com-
pared with areas near expan-
sion valve outlet and evapora-
tor. Low-pressure pipe is clogged
or crushed.
I
Check and repair malfunc-
tioning parts.
I Check compressor oil for

Air flow volume is not enough
or is too low. Evaporator is frozen.

Compressor discharge capac-
ity does not change. (Com-
pressor stroke is set at maxi-
mum length.) Replace compressor.
Low-pressure side sometimes
becomes negative.
AC354A
I Air conditioning system does
not function and does not
cyclically cool the compart-
ment air.
I The system constantly func-
tions for a certain period of
time after compressor is
stopped and restarted. Refrigerant does not discharge
cyclically.
"
Moisture is frozen at expan-
sion valve outlet and inlet. "
Water is mixed with refrigerant. I
Drain water from refrigerant
or replace refrigerant.
I Replace liquid tank.

Low-pressure side becomes
negative.
AC362A
Liquid tank or front/rear side of
expansion valve's pipe is
frosted or dewed. High-pressure side is closed
and refrigerant does not flow.
"
Expansion valve or liquid tank
is frosted. After the system is left at rest,
start it again in order to con-
firm whether or not problem is
caused by water or foreign
particles.
I
If the problem is due to
water, drain water from
refrigerant or replace refrig-
erant.
I If it is due to foreign
particles, remove expansion
valve and remove them with
dry and compressed air.
I If either of the above meth-
ods cannot correct the
problem, replace expansion
valve.
I Replace liquid tank.
I Check compressor oil for
contamination.
