Faulty Wheel Speed Sensor
Wheel Speed Sensor harness is open or shorted
Wheel Speed Sensor circuit poor electrical connection
Engine Light ON (or Service Engine Soon Warning Light)
The road situation is estimated with the help of a wheel speed sensor. The wheel speed sensor generates an AC voltage that increases with wheel speed every time there is a wheel rotation.
The frequency of the AC signal is used by the Electronic Body Control Module (EBCM) to calculate wheel speed. Engine Control Module (ECM) misfire detection diagnostic will be automatically deactivated once the wheel speed sensor detects a rough road condition.
