Redundant wheel speed sensors in a single package, in particular a wheel speed sensor system and a method of operating a wheel speed sensor system. The system comprises: at least one wheel speed sensor associated with a wheel comprising first and second wheel speed sensing elements arranged in a single package to generate first and second sensing signals; first and second signal processing units that process the sensing signal and generate first and second wheel speed signals; a signal combining unit communicatively coupled to the signal processing unit and the first and second electronic control units to process and combine the wheel speed signals and concurrently output a combined signal to the electronic control units; and a power management unit independently delivering electrical energy to the wheel speed sensing elements, the power management unit connected to the electronic control units such that the electrical energy is passed from one or both electronic control units to the power management unit.
