GENERAL DESCRIPTION
E30F80CC
The Wheel Speed Sensor (WSS) generates a waveform with a frequency proportional to the speed of the vehicle. The
signal generated by the WSS informs the ECM not only if the vehicle speed is low or high but also if the vehicle is or is
not moving. The ECM uses this signal to control the fuel injection, ignition timing, transaxle shift scheduling and torque
converter clutch scheduling. The WSS signal is also used to detect rough road conditions.
