DESICCANT
1.
Remove the condenser, and then remove the bottom
cap (B) with L wrench (A) from the condenser.
TORQUE: 20~25N.m (2.0~2.5kgf-m, 14.5~18.2lb-ft)

2.
Remove the desiccant (A) from condenser using a
long nose plier. Check for crumbled desiccant and
clogged bottom cap filter.

3.
Apply air conditioning compressor oil along the
O-rings and threads of the new bottom cap.
4.
Insert the new desiccant into the receiver drier tank.
The desiccant must be sealed in vacuum before it is
exposed to air for use.
5.
Install the new bottom cap to the condenser.
NOTE
-
Always replace the desiccant and bottom cap at
the same time.
-
Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil before
installing them. Be sure to use the right O-rings
for R-134a to avoid leakage.
-
Be careful not to damage the radiator and con-
denser fins when installing the condenser.
-
Be sure to install the lower mount cushions of
condenser securely into the holes.
-
Charge the system, and test its performance.

HEATING, VENTILATION AND AIR CONDITIONING
DESCRIPTION
EE9BED9D
A/C pressure transducer convert the pressure value of
high pressure line into voltage value after measure it. By
converted voltage value, engine ECM controls cooling fan
by operating it high speed or low speed. Engine ECM stop
the operation of compressor when the temperature of re-
frigerant line is so high or so low irregularly to optimize air
conditioning system.
INSPECTION

1.
Measure the pressure of high pressure line by mea-
suring voltage output between NO.1 and NO.2 termi-
nals.

2.
Inspect the voltage value whether it is sufficient to be
regular value or not.
Voltage = 0.025 * Pressure + 0.1 [kgf/cm²]
Voltage = 0.001758 * Pressure + 0.074162 [PSIA]
3.
If the measured voltage value is not specification, re-
place the A/C pressure transducer.
REPLACEMENT
EC52DA5D
1.
Disconnect the negative (-) battery terminal.
2.
Recover the refrigerant with a recovery/charging sta-
tion.
3.
Disconnect A/C pressure transducer connector (3P)
(A).
