If your vehicle has 4 high resolution wheel speed sensors, why does it need a vehicle speed sensor? Modern vehicles with 11 speed transmissions, all wheel drive, transfer cases, and more need to know the vehicle speed now more than ever. This “vehicle speed” is also known as the output shaft speed. These sensors are also used for the odometer on the vehicle and if not functioning properly, the vehicle mileage and speed will not show up.
