Sebring Sedan V6-3.5L (2009)
Wheel Speed Sensor: Description and Operation
Wheel Speed Sensor - Description
Front
DESCRIPTION
The antilock brake system uses two-wire wheel speed sensors, known as active wheel speed sensors. The sensors use an electronic principle known as
magneto-resistive to help increase performance and durability. The sensors convert wheel speed into a small digital signal. A Wheel Speed Sensor
(WSS) is used at each wheel. A magnetic pole encoder serves as the trigger mechanism for each sensor. At each wheel of the vehicle there is one wheel
speed sensor and one encoder.
A front wheel speed sensor (3) is attached to a mounting boss on each front knuckle (4). The encoder is an integral part of the hub and bearing.
WSS air gaps are not adjustable.

The rear wheel speed sensor (2) head is mounted to the rear of the hub and bearing by a screw (1). The encoder is integral to the hub and bearing
assembly. The encoder is serviced as part of the rear hub and bearing.
