The vehicle speed sensor (VSS) in a 2005 Chevrolet Silverado is a magnetic generator responsible for monitoring rear wheel speed. When the vehicle is moving, the VSS produces an AC voltage with a frequency proportional to the vehicle's speed. This signal is transmitted to the speedometer on the instrument panel, where the vehicle's speed is displayed. The power-train control module also uses the signal to monitor various other transmission and engine functions. Replacing the VSS in a 2005 Silverado is simple and straightforward.
Raise the Silverado with a jack and lower it onto jack stands to secure it.
Lift the hood and prop it open. Locate the VSS mounted to the side of the transmission case.
Pull the connector out of the VSS electrical fitting.
Remove the mounting bolt with a socket wrench. Remove the VSS from the side of the transmission case.
Install the O-ring supplied with the new VSS. Attach the VSS to the transmission case.
Reposition and tighten the mounting bolt with a socket wrench.
Push the connector into the VSS electrical fitting. Close the hood.
