test system. Ensure A/C system is operating properly.
Orifice Tube Replacement Kit (Villager)
1) Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Drain engine coolant to a level below
thermostat. Remove upper radiator hose and bracket to gain access to
condenser end of liquid line. Remove condenser-to-evaporator liquid
line from vehicle.
2) Locate orifice tube in metal portion of liquid line, at
indentation. See Fig. 20. Make a 4" (102 mm) index line on liquid line
with indentation at the midpoint. Cut a 2.5" (63.5 mm) section from
liquid line with indentation in the middle, at least 1" (25.4 mm) from\
start of closest bend. Clean out liquid line to remove contaminants.
3) Lubricate orifice tube replacement kit compression nuts
and rings with refrigerant oil and install on liquid line. See Fig. 21
. Ensure flow direction arrow points toward evaporator. Ensure index
line on liquid line is properly aligned for installation. Tighten
compression nuts to 65-70 ft. lbs. (88-95 N.m).
4) To complete installation, reverse removal procedure.
Lubricate "O" rings with refrigerant oil. Evacuate, charge and leak
test system. Ensure A/C system is operating properly.

4) Scan tool will automatically calculate system charge.
Depending on system charge condition, corrections are made 2 ounces at
a time. Each time a correction is made, recheck readings to ensure
proper charge. For system refrigerant capacity, see REFRIGERANT OIL &
REFRIGERANT SPECIFICATIONS article.
Breeze, Cirrus, Concorde, Intrepid, LHS, Stratus & 300M
(Manifold Gauge Set Method)
1) Attach clamp-on Thermocouple (80PK-1A) to liquid line, as\
close to condenser outlet as possible. Attach manifold gauge set to
vehicle.
2) Set parking brake, and place transaxle in Park position.
Start engine and allow to idle. Set A/C controls to outside air, panel
mode, full cool, and high blower speed. Turn A/C on, and open windows.
Operate system for a few minutes to allow system to stabilize.
3) Place cardboard over front grille area, to block airflow
through part of condenser, to set A/C pressure to 260 psi (18.3
kg/cm
). This will stop cooling fans from alternating speeds and
maintain constant pressure.
4) Record temperature reading at liquid line and discharge
pressure reading on gauges. Compare readings with values in
REFRIGERANT CHARGE LEVEL table.
5) Depending on system charge condition, corrections are made
2 ounces at a time. Each time a correction is made, recheck readings
to ensure proper charge. For system refrigerant capacity, see
REFRIGERANT OIL & REFRIGERANT SPECIFICATIONS article.

DTC P1762: GOV PRESS SEN OFFSET VOLTS TOO LOW OR HIGH
Circuit Description
Circuit is monitored continuously while key is on and engine

seconds. Test must fail 3 times to set code.
Possible Causes
* Solenoid pack connector 5 volt supply circuit open.
* Governor pressure sensor ground circuit open.
* Governor pressure sensor wiring harness and/or connectors
defective.
* Transmission fluid burnt or oil pan has excessive debris.
Diagnostic Procedures
1) Using scan tool, read DTCs. On AN and DN bodies, go to
next step. On all except AN and DN bodies, if DTC SPECIFIC GOOD TRIPS
counter is not displayed or displayed count is not "0", go to step 9).
If DTC SPECIFIC GOOD TRIPS counter is displayed and displayed count is
"0", go to next step.
