Answer 1

HI there

This code is for a problem with the vehicle speed sensor circuit. This car uses input from the abs control unit to the computer to tell what speed the car is running. This is usually a communication error between the control modules. Typically you need a scan tool to make a proper diagnosis that can see live data into the ECM and the ABS computer.
