Abstract
The disclosure provides a system for magnetic self test. The system includes an electronic control unit (ECU) including a controller. Only one sensor is electrically coupled to the ECU, wherein the sensor includes a sensing element, a signal conditioning element electrically coupled to the sensing element and the controller, and a wire-on-chip (WOC) device disposed next to the sensing element. The system further includes a WOC stimulus element provided in the ECU or the sensor to drive the WOC to create a WOC magnetic field, wherein the system is configured to compare an expected sensor output signal that is caused by the WOC magnetic field with an actual sensor output signal by the controller or an additional signal assessment element in the sensor to identify whether the sensor is still functioning correctly.
