LGLG519A

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.

DTC DESCRIPTION

E24AFA68

Checking output signals from wheel speed sensor or ABS control unit or VSS every 30 sec. under detecting condition,
if an signal is in the detecting condition for more than 20 sec., PCM sets P0501. MIL(Malfunction Indication Lamp) turns
on when the malfunction lasts till cosecutive 2 driving cycle.
