Abstract
Methods and systems are provided for monitoring a fuel injector of an internal combustion engine. In one embodiment, a method includes: receiving a set of feature data, the feature data sensed from a fuel injector during a fuel injection event; processing, by a processor, the set of feature data with a machine learning model to generate a prediction of a fault status; and selectively generating, by the processor, a notification signal based on the prediction.
