An apparatus and method for resistive short circuit immunity for wheel speed sensor interface on a braking system. In one embodiment the apparatus includes a first circuit for generating a first periodic signal based on first current transmitted to a wheel speed sensor and a second circuit for generating a second periodic signal based on second current some or all of which is received from the wheel speed sensor. A circuit is provided for selecting the first periodic signal for output if a magnitude of the second current is greater than a magnitude of the first current, or the second periodic signal for output if magnitude of the second current is not greater than the magnitude of the first current. The selected first or second periodic signal contains information relating to a speed of a wheel that is associated with the wheel speed sensor.
