Abstract

A system includes one or more sensors that generate sensor measurement signals based on characteristics of one or more components of an engine control subsystem. The system also includes a controller circuit having one or more processors. The controller circuit is programmed to perform operations in response to instructions stored on a non-transitory memory. The operations performed by the controller circuit include acquiring the sensor measurement signals from the one or more sensors. The sensor measurement signals include electrical characteristics. The operations performed also include comparing the electrical characteristics of the sensor measurement signals with operational threshold corresponding to the one or more sensors, determining a set of candidate sensors having a fault based on the comparison, and displaying a troubleshoot window based on a select candidate sensor.
