Jeep Liberty KJ. Manual — part 1123
SENSOR- WHEEL SPEED-REAR
REMOVAL
1. Raise and support the vehicle.
2. Remove the wheel speed sensor mounting bolt (2)
from the rear support plate (1).
3. Remove the wheel speed sensor from the support
plate (1).
4. Disconnect the wheel speed sensor electrical
connector.
INSTALLATION
1. Insert the wheel speed sensor (2) through the sup-
port plate (1).
2. Tighten the wheel speed sensor bolt (2) to 12-14
N·m (106-124 in. lbs.).
3. Secure the wheel speed sensor wire to the routing
clips. Verify that the sensor wire is secure and
clear of the rotating components.
4. Reconnect the wheel speed sensor electrical con-
nector.
5. Lower the vehicle.

SENSOR-DYNAMICS
DESCRIPTION
The Yaw Rate and Lateral Acceleration Sensors are
housed into one unit known as the Dynamics Sensor
(3). The sensor is used to measure side-to-side (Lat-
eral) motion and vehicle rotational sensing (how fast
the vehicle is turning - Yaw).
Yaw and Lateral Acceleration Sensors cannot be ser-
viced separately. The entire Dynamics Sensor (3)
must be replaced when necessary.
REMOVAL
1. Remove the center console (Refer to 23 - BODY/
INTERIOR/FLOOR CONSOLE - REMOVAL).
2. Disconnect
electrical
connector
(2)
from
the
dynamics sensor (3).
3. Remove the two nuts (1) securing the sensor to the
floor.
4. Remove the sensor (3).

SENSOR-STEERING ANGLE
DESCRIPTION
NOTE: Steering angle sensor is part of the airbag clockspring and is not serviced separately from the clock-
spring.
Under transient cornering conditions the lateral acceleration sensor does not measure the true sway force on the
car. In order to compensate for this the system uses the driver’s steering command (Steering angle sensor) and
vehicle speed to estimate the true sway force. This signal is matched with the lateral acceleration sensor signal to
ensure a significantly-reduced transient sway of the vehicle body.
REMOVAL
NOTE: Steering angle sensor is part of the airbag clockspring and is not serviced separately from the clock-
spring.
1. For removal of the steering angle sensor (Refer to 8 - ELECTRICAL/RESTRAINTS/CLOCKSPRING -
REMOVAL).
INSTALLATION
NOTE: Steering angle sensor is part of the airbag clockspring and is not serviced separately from the clock-
spring.
1. For installation of the steering angle sensor (Refer to 8 - ELECTRICAL/RESTRAINTS/CLOCKSPRING - INSTAL-
LATION).
