Early detection and avoidance of turbocharger failure are provided by monitoring vibration of the turbocharger rotor using a vibration sensor and providing the output signal of the sensor to a controller programmed to periodically compare the magnitude of the vibration to a predetermined maximum limit. Upon the magnitude of the vibration exceeding the maximum limit, thus indicating a potential abnormal condition, the controller issues a command to a fuel controller for the engine to cause the fuel controller to place the engine in a predetermined safe operating mode selected to reduce the likelihood of turbocharger and engine damage from the abnormal condition.
