Standard Motor Vehicle Speed Sensors

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.

Holstein Parts Vehicle Speed Sensors

Vehicle speed sensors measure wheel speeds and provide this information to the vehicles ECU (Electronic Control Unit). The ECU then calculates ignition timing, transmission shift points, and air/fuel ratios for the vehicle. Data from the Vehicle Speed Sensor is also used in cruise control systems to maintain a constant speed. Holstein Parts focuses on using only the highest quality materials, manufactured to exacting standards for an aftermarket product that is truly built to match or exceed the OE part. Holstein Parts vehicle speed sensors line has superior coverage for domestic and import applications.

ATS Diesel Performance TPS Signal Conditioners

ATS Diesel Performance TPS signal conditioners are designed to help repair and prevent hunting in and out of torque converter lockup between 3rd and 4th gears. This is done by conditioning the TPS signal, which allows the transmission to have better shift characteristics. The factory TCM tune is very sensitive. By adding ATS Diesel Performance TPS signal conditioners the signal to the TCM will not be as dramatic.
