VEHICLE SPEED SENSOR
REMOVAL
(1) Raise vehicle on hoist.
(2) Disconnect the speed sensor connector (Fig.
279).CAUTION: Clean area around speed sensor before
removing to prevent dirt from entering the transaxle
during speed sensor removal.
(3) Remove speed sensor retaining bolt (Fig. 279).
(4) Remove speed sensor from transaxle.
CAUTION: Carefully remove vehicle speed sensor
so that sensor drive gear does not fall into trans-
axle. Should sensor drive gear fall into the trans-
axle during sensor removal, drive gear must be
reattached to sensor.
(5) Remove speed sensor drive gear from speed
sensor.
INSTALLATION
(1) Install pinion gear to speed sensor (Fig. 279) .
(2) Using a NEW o-ring, install the speed sensor
to the transaxle (Fig. 279) .
(3) Install the bolt and torque to 7 N´m (60 in.
lbs.).
(4) Connect speed sensor connector (Fig. 279) .
(5) Lower vehicle and road test to verify proper
speedometer operation.

DIAGNOSIS AND TESTING - TIRE AND WHEEL
VIBRATION
Tire and wheel imbalance, runout and force varia-
tion can cause vehicles to exhibit steering wheel
vibration.
VISUAL INSPECTION
Visual inspection of the vehicle is recommended
prior to road testing or performing any other proce-
dure. Raise vehicle on a suitable hoist. (Refer to
LUBRICATION & MAINTENANCE/HOISTING -
STANDARD PROCEDURE)

(a) Align the valve notch in the wheel cover with
the valve stem on the wheel.
(b) At the same time, align the two holes in the
wheel cover having the retaining tabs with the two
installed wheel nuts (Fig. 15).
(c) Press in on center of wheel cover until wheel
cover retaining tabs push past and engage rear of
previously installed wheel mounting nuts (Fig. 15).
This will hold the wheel cover in place.
(4) Install andlightly tightenthe three remain-
ing wheel mounting nuts, securing the wheel cover in
place (Fig. 12).
(5) Progressively tighten all five wheel mounting
nuts in the proper sequence (Fig. 16). Tighten wheel
nuts to a torque of 135 N´m (100 ft. lbs.).
(6) Lower the vehicle.TIRE PRESSURE MONITORING
(TPM)
DESCRIPTION
Some versions of this vehicle are equipped with a
Tire Pressure Monitoring (TPM) system. It monitors
air pressure in the four road tires (excludes spare).
Pressure in the spare tire is not monitored.
There is a sensor (transmitter) in each of the vehi-
cle's four road wheels. The system alerts the driver
when tire pressure falls outside predetermined
thresholds (pressure too low or too high). A message
is then displayed on the Electronic Vehicle Informa-
tion Center (EVIC) located in the overhead console.
For further information, refer to the Owners Man-
ual or the appropriate diagnostic information.
OPERATION
The Tire Pressure Monitoring (TPM) system uses
radio and sensor technology to monitor tire air pres-
sure levels. Sensors, mounted to each road wheel as
part of the valve stem, transmit tire pressure read-
ings to a receiver located in the overhead console.
These transmissions occur once every minute at
speeds over 20 mph (32 km/h). The Tire Pressure
Monitoring system remains active even if no tire
pressure related message is displayed in the EVIC.
If any road tire pressure has exceeded the low or
high pressure threshold (refer to chart below), the
TPM system will display a message in the EVIC and
sound a chime. This message will be displayed for
the rest of the ignition cycle, or until either the Low/
High Tire pressure condition has been corrected. If
the C/T, MENU, STEP or RESET button is pressed,
the message is replaced by the new message
requested; however, if the Low/High Tire condition
has not been corrected, the Low/High Tire pressure
message will again be displayed.
If a road tire is replaced by the spare, the TPM
system will detect the swap and the message9SPARE
TIRE IN USE? Y/N9(along with a chime) will be dis-
played.
For further information, refer to the Owners Man-
ual or the Appropriate Diagnostic Information.
TPM THRESHOLD PRESSURES
High Pressure ON Threshold 48 PSI (331 kPa)
High Pressure OFF Threshold 43 PSI (296 kPa)
Placard Pressure (Cold) 36 PSI (248 kPa)
Low Pressure OFF Threshold 33 PSI (228 kPa)
Low Pressure ON Threshold 28 PSI (193 kPa)
