A method and apparatus for resistive short circuit immunity for wheel speed sensor interface on braking system. In one embodiment the apparatus includes a first circuit for transmitting a first current to a wheel speed sensor, and a second circuit for receiving a second current from the wheel speed sensor. Another circuit is coupled to the first and second circuits and configured to detect and respond to a near zero resistive short between the wheel speed sensor and ground. In this embodiment the circuit is configured to detect the near zero resistive short based on a direct or indirect comparison between magnitudes of the first and second currents to a first predetermined value, and based on a direct or indirect comparison between magnitudes of the first and second currents to a second predetermined value.
