CRUISE CONTROL SYSTEM, Diagnostic DTC:P0500

DTC Code DTC Name
P0500 Vehicle Speed Sensor Malfunction

The master cylinder solenoid (skid control ECU) converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of these pulse signals.
