The regulator is calibrated to maintain fuel system
operating pressure of approximately 339 kPa   34
kPa (49.2 psi   5 psi) at the fuel injectors. It contains
a diaphragm, calibrated springs and a fuel return
valve. The internal fuel filter is also part of the
assembly.
Fuel is supplied to the filter/regulator by the elec-
tric fuel pump. The regulator acts as a check valve to
maintain some fuel pressure when the engine is not
operating. This will help to start the engine. A second
check valve is located at the outlet end of the electric
fuel pump.
If fuel pressure at the pressure regulator exceeds
approximately 49 psi, an internal diaphragm closes.
Excess fuel is then routed into a separate fuel return
line and returned to the fuel tank through the top of
the fuel pump module.
Both fuel filters (at bottom of fuel pump module
and within fuel pressure regulator) are designed for
extended service. They do not require normal sched-
uled maintenance. Filters should only be replaced if
a diagnostic procedure indicates to do so.
REMOVAL
The combination Fuel Filter/Fuel Pressure Regula-
tor is remotely mounted to the vehicle body, above
the rear axle and near the front of the fuel tank (Fig.
4) or (Fig. 5).
(1) Perform Fuel System Pressure Release Proce-
dure.
(2) Disconnect negative battery cable at battery.
(3) Raise vehicle.
(4) Clean area around 3 filter/regulator fittings.
(5) Disconnect fuel supply, fuel return and fuel
pressure lines at filter/regulator (Fig. 4) . Refer to
Quick-Connect Fittings.
(6) Remove 2 mounting bolts (Fig. 5) and remove
filter/regulator.
INSTALLATION
The combination Fuel Filter/Fuel Pressure Regula-
tor is remotely mounted to the vehicle body, above
the rear axle and near the front of the fuel tank (Fig.
4) or (Fig. 5).
(1) Before installing filter/regulator, be sure all fit-
tings are cleaned of all dirt and contaminants.
(2) Be sure o-ring is positioned into fuel return fit-
ting in filter/regulator.

TIRE PRESSURE MONITORING
DESCRIPTION
The EVIC will monitor the tire pressure signals
from the five tire sensors and determine if any tire
has gone below the low pressure threshold or raised
above the high pressure threshold. Refer to the table
below.
LOW TIRE PRESSURE THRESHOLDS
SYSTEM STATUS
INDICATORTIRE PRESSURE
ON 179 kPa (26 PSI)
OFF 214 kPa (31 PSI)

INDICATORTIRE PRESSURE
ON 310 kPa (45 PSI)
OFF 276 kPa (40 PSI)
The Remote Tire Pressure Monitors (RTPM) are
not internally serviceable. For a Sensor Failure or
Low Battery fault, the RTPM must be replaced.
OPERATION
If equipped with the Tire Pressure Monitoring Sys-
tem, each of the vehicle's five wheels will have a
valve stem with a pressure sensor and radio trans-
mitter built in. Signals from the tire pressure sensors
are received and interpreted by the Electronic Vehi-
cle Information Center (EVIC). A sensor in a
mounted wheel will broadcast its detected pressure
once per minute when the vehicle is moving faster
than 40 km/h (25 mph). The spare tire sensor will
broadcast once every hour. Each sensor's broadcast is
uniquely coded so that the EVIC can determine loca-
tion. The individual tire pressures can be displayed
graphically on the EVIC
DIAGNOSIS AND TESTING - TIRE PRESSURE
MONITORING SYSTEM
All Tire Pressure Monitoring System Faults are
specific to one location. If a9BATTERY LOW9or
9SENSOR FAILURE9fault is detected, the location
will be displayed. The appropriate sensor/transmitter
can then be replaced. If a single sensor/transmitter
cannot be detected by the EVIC, replace that sensor
transmitter. If none of the sensors/transmitters can
be detected, refer to symptoms in the EVIC section.
For additional system description and diagnosis,
refer to Tire Pressure Monitoring in the Body Diag-
nostic manual.
SENSOR
REMOVAL - TIRE PRESSURE SENSOR/
TRANSMITTER
(1) Remove the tire/wheel from the vehicle.
CAUTION: When removing the stick on balancing
weights from the wheel, do not use an abrasive
cleaner or a cleaner which will damage the protec-
tive finish on the wheel.
(2) Remove the balancing weights from the wheel.
NOTE: The cap used on this valve stem contains an
O-ring seal to prevent contamination and moisture
from entering the valve stem. Retain this valve stem
cap for re-use. Do not substitute a regular valve
stem cap in its place.
(3) Remove the cap from the valve stem.
NOTE: The valve stem used on this vehicle is made
of aluminum and the core is nickel plated brass.
The original valve stem core must be reinstalled
and not substituted for a valve stem core made of a
different material. This is required to prevent corro-
sion in the valve stem caused by the different met-
als.
(4) Using the appropriate tool, remove the core
from the valve stem (Fig. 20).
(5) Let the tire fully deflate.
