Abstract
A control system for an engine includes an injection control module, a processing module, and a malfunction detection module. The injection control module commands a fuel injector to operate in a split injection mode. The processing module that measures engine vibration during a period after commanding the split injection mode. The malfunction detection module detects a malfunction of the fuel injector based on a comparison between the measured engine vibration and expected engine vibration.
