A turbocharger protection system for an engine system that includes a particulate filter and a turbocharger comprises a delta pressure estimator that estimates a pressure difference in a particulate filter. A pressure factor estimator module estimates a pressure factor based on the difference and barometric pressure. A fuel limit estimator module protects the turbocharger by selectively limiting fuel injection to the engine based on the pressure factor.
