Abstract

Embodiments herein relate to a system and method for detecting an open circuit in a sensor measurement system. The system including a sensor (22a - 22n) having a direct current (DC) output, operably connected to a wiring harness (27a - 27n) and configured to transmit a sensor signal, and a controller (100), the controller (100) operably connected to the wiring harness (27a - 27n). The controller (100) is configured execute a method including receiving a sensor signal from the sensor, AC coupling an AC signal with the sensor signal to form a coupled signal, measuring the coupled signal, determining if an open circuit is present based on the coupled signal and characterizing the sensor as failed if the open circuit is detected.
