• Vehicle Speed Sensor (VSS) signal to modify engine functions and initiate diagnostic routines. 
• The VSS signal originates from a sensor measuring transmission/transaxle output speed or wheel speed. 
• Different types of sensors have been used depending on models and applications. 
• On some vehicles, the vehicle speed sensor signal is processed in the combination meter and then sent to the ECM. 
• On some anti-lock brake system (ABS) equipped vehicles, the ABS computer processes the wheel speed sensor signals and sends a speed sensor signal to the combination meter and then to the ECM. You will need to consult the EWD to confirm the type of system you are working on.
