Abstract
A control system for an engine system includes a temperature sensor and a diagnostic module. The temperature sensor measures an outlet temperature at an outlet of a cooling system. The diagnostic module estimates the cooling fluid temperature, determines the cooling performance based on the outlet temperature and the cooling fluid temperature, and selectively diagnoses a fault in the cooling system based on the cooling performance and a predetermined threshold.
