Replace your worn or malfunctioning vehicle speed sensor with one of these Standard Motor Products vehicle speed sensors. Depending upon a vehicle's equipment, the vehicle speed sensor commonly called a VSS may influence or control more systems than any other single sensor. Early-model vehicle speed sensors were just used to regulate the cruise control and control transmission shifts. Now, with OBD-II, vehicle speed is considered a part of the overall engine operating strategies, affecting both fuel delivery and ignition timing. The operations of the idle-air control valve and canister-purge cycle are regulated, in part, by the VSS. Automatic transmissions need VSS data to provide the best performance and mileage. Torque converter clutch operation is controlled by the VSS. In an electronically shifted transmission, VSS signals, instead of hydraulic pressure in the valve body, are used to determine shift points. Don't take chances with your vehicle's performance--insist on Standard Motor Products quality vehicle speed sensors.
