This article applies to the Chevrolet Silverado GMT800 (1999-2006). A vehicle speed sensor (VSS) transmits the transfer case, transaxle, and/or wheel speeds to the truck's electronic control module (ECM). The on-board computer then uses this information to alter various engine and transmission functions, such as ignition timing, air-to-fuel mixture, and transmission shift points. If your Silverado's brakes are stiffer than normal, the transmission is slow to engage, the overdrive light blinks on and off, the speedometer stops working or behaves erratically, or the check engine light turns on, then the vehicle speed sensor (VSS) may have stopped working. You can make sure that the VSS is the root cause of these symptoms by pulling your truck's trouble codes.
