STANDARD PROCEDURE - CLEANING FUEL
SYSTEM PARTS
CAUTION: Cleanliness cannot be overemphasized
when handling or replacing diesel fuel system com-
ponents. This especially includes the fuel injectors,
high-pressure fuel lines, fuel rail, and fuel injection
pump. Very tight tolerances are used with these
parts. Dirt contamination could cause rapid part
wear and possible plugging of fuel injector nozzle
tip holes. This in turn could lead to possible engine
misfire. Always wash/clean any fuel system compo-
nent thoroughly before disassembly and then air
dry. Cap or cover any open part after disassembly.
Before assembly, examine each part for dirt, grease
or other contaminants and clean if necessary. When
installing new parts, lubricate them with clean
engine oil or clean diesel fuel only.

BOOST PRESSURE SENSOR
DESCRIPTION
The boost pressure sensor is mounted to the top of
the intake manifold. The sensor allows the ECM to
monitor air pressure within the intake manifold. The
boost pressure sensor is also used as an intake air
temperature sensor (Fig. 5).
OPERATION
When the intake manifold pressure is low (high
vacuum) sensor voltage output is 0.25-1.8 volts at the
ECM. When the intake manifold pressure is high due
to turbo boost, sensor voltage output is 2.0-4.7 volts.
The sensor receives a 5-volts reference from the
ECM. Sensor ground is also provides by the ECM.
The ECM uses boost pressure combined with intake
air temerature to determine the volume of air enter-
ing the engine.
DIAGNOSIS AND TESTING - BOOST PRESSURE
SENSOR
If the boost pressure sensor fails, the ECM records
a DTC into memory and continues to operate theengine in one of the three limp-in modes. When the
ECM is operating in this mode, a loss of power will
be present, as if the turbocharger was not operating.
The best method for diagnosing faults with the boost
pressure sensor is with the DRB IIItscan tool. Refer
to the Diesel Powertrain Diagnostic Manual for more
information.
Refer to On-Board Diagnostics in Emissions Con-
trol System for a list of Diagnostic Trouble Codes
(DTC's) for certain fuel system components.
INTAKE AIR TEMPERATURE
SENSOR
DESCRIPTION
The boost pressure sensor/intake air temperature
sensor is located in the top of the intake manifold
(Fig. 6). The intake air temperature sensor is used to
measure the intake air temperature. The intake air
temperture sensor is a dual purpose sensor. It is also
used as a boost pressure sensor.
OPERATION
The intake air temperature sensor is a negative
temperature coefficient (NTC) thermistor (resistance
varies inversly with temperature). This means at
cold air temperature its resistance is high, sothe volt-
age signal will be high. As intake air temperature
increases, sensor resistance decreases and the signal
voltage will be low. This allows the sensor to provide
an analog voltage signal (0.2-4.8 volts) to the ECM.
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove engine cover retaining bolts and cover-
(Refer to 9 - ENGINE COVER - REMOVAL).

TEMPERATURE SENSOR
RGFUEL INJECTION14a-13
ACCELERATOR PEDAL POSITION SENSOR (Continued)

OPERATION
The ECM uses the mass air flow (MAF) sensor to
measure air density. The MAF sensor contains a
ceramic element. A signal voltage is provided to the
element. As engine speed increases, airflow across
the ceramic element increases. Changes in air flow
and air density cause the temperature of the ceramic
element to fluxuate. The ceramic element changes
resistance respectively to changes in temperature.
The change in resistance varies the signal voltage
output to the ECM. The diesel power relay supplies
battery power the to MAF sensor. Ground is provided
by the ECM. The MAF sensor signal is provided by
the ECM.
REMOVAL
(1) Disconnect negative battery cable.
(2) Disconnect MAF sensor electrical connector
(Fig. 9).

The NV T850 5-speed transaxle (Fig. 1) is a con-
stant-mesh manual transaxle that is synchronized in
all gear ranges, including reverse.
The transaxle consists of three major sub-assem-
blies: the input shaft, intermediate shaft, and differ-
ential assembly. The transaxle shift system consists
of a mechanical shift cover, rails, forks, and cables.
The unique design of this shift system provides a
higher mechanical advantage, resulting in less fric-
tion and lower shift cable loads for smoother, more
positive operation.
The NV T850 transaxle is available with the 2.4L
Gas and 2.5L Turbo Diesel engine options. Unique
gearing tailored to the performance characteristics of
each engine provides optimum driveability, gradabil-
ity, and acceleration. The gear ratios are as follows:

TRANSAXLE IDENTIFICATION
NOTE: Since transaxles use unique gear ratios for
each of the two engine applications, it is imperative
that the transaxle is properly identified, and the cor-
rect transaxle assembly number is used when
ordering service parts.The transaxle model, assembly part number, build
date, and final drive ratio (FDR) can be found on a
metal tag fastened to the transaxle case on the bell-
housing (Fig. 2). A barcode label is also glued to the
transaxle bellhousing, and it too includes the trans-
axle part number.

WARNING: REFER TO THE APPLICABLE WARN-
INGS AND CAUTIONS FOR THIS SYSTEM BEFORE
PERFORMING THE FOLLOWING OPERATION.
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - WARNING - A/C PLUMBING)
and (Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - CAUTION - A/C PLUMBING).
NOTE: The proper amount of R-134a refrigerant for
the refrigerant system in this model is:
²Single or Dual Zone (Front Unit Only - 2.5L Die-
sel) ± 0.91 kilograms (2.00 pounds or 32 ounces)
²Single or Dual Zone (Front Unit Only) - 0.96
kilograms (2.13 pounds or 34 ounces)
²Three Zone (Front and Rear Units) - 1.31 kilo-
grams (2.88 pounds or 46 ounces)
The procedure that follows should be used to deter-
mine whether the refrigerant system contains the
proper refrigerant charge. Symptoms of an improper
refrigerant charge (low) include: poor air conditionerperformance, fog emitted from the air conditioner out-
lets, a hissing sound from the expansion valve/evapo-
rator area. There are two different methods with
which the refrigerant charge level may be tested:
²Using a DRBIIItscan tool, a thermocouple and
the Charge Determination Chart (Fig. 3). Refer to
the appropriate diagnostic information.
²Using a manifold gauge set, a thermocouple and
the Charge Determination Chart (Fig. 3).
A temperature probe is required to measure liquid
line temperature. The clamp-on, Type K thermocou-
ple temperature probe used in this procedure is
available through the DaimlerChrysler Professional
Service Equipment (PSE) program. This probe (PSE
#66-324-0014 or #80PK-1A) is compatible with tem-
perature-measuring instruments that accept Type K
thermocouples, and have a miniature connector
input. Other temperature probes are available
through aftermarket sources; however, all references
in this procedure will reflect the use of the probe
made available through the PSE program.
In order to use the temperature probe, a digital ther-
mometer will also be required. If a digital thermometer
is not available, an adapter is available through the
PSE program that will convert any standard digital
multimeter into a digital thermometer. This adapter is
designed to accept any standard Type K thermocouple.
If a digital multimeter is not available, this tool is also
available through the PSE program.
NOTE: When connecting the service equipment
couplings to the refrigerant system service ports,
be certain that the valve of each coupling is fully
closed. This will reduce the amount of effort
required to make the connection.
(1) Remove the caps from the refrigerant system
service ports and attach a manifold gauge set or a
R-134a refrigerant recovery/recycling/charging sta-
tion that meets SAE Standard J2210 to the refriger-
ant system.
(2) Attach a clamp-on thermocouple to the liquid
line. The thermocouple must be placed as close to the
A/C pressure transducer as possible to accurately
observe liquid line temperature.
(3) Bring the refrigerant system up to operating
temperature and pressure. This is done by allowing
the engine to run at idle under the following condi-
tions for five minutes.
(a) Front windows are open.
(b) Transaxle in Park.
(c) Front heater-A/C controls set to outside air,
full cool, panel mode, blower high, and compressor
engaged.
(d)
If the vehicle is so equipped, the rear heater-
A/C controls must be set to full cool and blower high.

(4) Raise the liquid line (discharge) pressure to
about 1793 kPa (260 psi) by placing a piece of card-
board over part of the front side of the condenser. To
place the cardboard properly, remove the upper radi-
ator sight shield from the front fascia. Cover only
enough of the condenser to raise and maintain the
liquid line pressure at the specified level.
(5) Observe the liquid line (discharge) pressure
and liquid line temperature. Using the Charge Deter-
mination Chart (Fig. 3), determine whether the
refrigerant system is operating within the Proper
Charge Range.
(a) If the refrigerant system is operating in the
Undercharged area of the chart, add 0.057 kilo-
gram (0.125 pound or 2 ounces) of refrigerant to
the system.
(b) If the refrigerant system is operating in the
Overcharged area of the chart, reclaim 0.057 kilo-
gram (0.125 pound or 2 ounces) of refrigerant from
the system.
(6) Recheck the system charge level following each
refrigerant adjustment. Continue this process until
the system readings are in the Proper Charge Range
area on the Charge Determination Chart (Fig. 3).DIESEL SUPPLEMENTAL
HEATER - DCHA
DESCRIPTION
Vehicles equipped with the optional diesel engine are
also equipped with a supplemental heater unit. This
unit is mounted under the vehicle and operates similar
to an oil fired furnace. The heater burns small
amounts of fuel to provide additional heat to the cool-
ant. Coolant is routed from the engine, to the supple-
mental heater, and then to the front heater core. This
provides additional heat to the passenger compart-
ment. The system is interfaced to the vehicles on-board
computer systems and DRB-III diagnostics.

OPERATION
The supplemental heater unit is activated via the
temperature slide control or knob on the vehicle HVAC
control unit. If the control slide or knob is moved to or
above the upper set point the heater is activated. The
unit can operate in a full or partial load range as well
as an idle mode all dependent on the engine coolanttemperature. The heater unit will also turn off if the
HVAC temperature control is lowered to less than the
lower set point. The heater unit can take up to three
minutes to completely shut down when either the
heater temperature is set below the lower set point or
the vehicle ignition is shut down.
DIAGNOSIS AND TESTING - DIESEL SUPPLEMENTAL HEATER - DCHA
The following table lists possible fault symptoms of
diesel fueled heaters.
SYMPTOM POSSIBLE CAUSES
Smell of diesel fuel Check heater system integration in vehicle's fuel system. Check fuel
lines for leakage, kinks or obstructions. If OK, Inspect the inlet muffler,
