A system includes a turbocharger and at least one sensor disposed adjacent the turbocharger. The at least one sensor is configured to detect one or more resonance frequencies of the turbocharger. The system also includes a controller configured to receive a signal from the at least one sensor representative of the detected one or more resonance frequencies of the turbocharger and to analyze the one or more resonance frequencies to determine one or more characteristics of the turbocharger.
