CRUISE CONTROL SYSTEM (except 1WW), Diagnostic DTC:P0500

DTC Code	DTC Name
P0500	Vehicle Speed Sensor Malfunction

DESCRIPTION

The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ECU. The skid control ECU converts these wheel speed signals into a pulse signal and outputs it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of this pulse signal.
