Abstract
An engine control system includes a determination module and a detection module. The determination module, based on an engine vibration signal generated by an engine vibration sensor, determines a frequency of engine vibration and determines a crankshaft position corresponding to the engine vibration. The detection module detects engine oil aeration and starvation when the frequency and crankshaft position are greater than predetermined thresholds, respectively.
