A wheel speed sensor system (100) for a vehicle (10) and a method of operating the same, said system (100) comprising at least one wheel speed sensor (1) associated with a wheel (11) of the vehicle (10), the at least one wheel speed sensor (1) comprising first and second wheel speed sensing elements (2, 3) arranged in a single package to generate first and second sensed signals (2.1, 3.1); first and second signal treatment units (4, 5) processing the sensed signals (2.1, 3.1) and generating first and second wheel speed signals (4.1, 5.1); a signal combination unit (6) communicatively coupled to the signal treatment units (4, 5) and to first and second electronic control units (8, 9), to process and combine the wheel speed signals (4.1, 5.1) and simultaneously output a combined signal (6.1) to the electronic control units (8, 9); and a power management unit (7) independently delivering electrical energy (7.1, 7.2) to the wheel speed sensing elements (2, 3), wherein the power management unit (7) is connected to the electronic control units (8, 9) so that the electrical energy (8.1, 9.1) is transferred from one or both the electronic control units (8, 9) to the power management unit (7).
