Abstract
A diagnostic system for performing engine material temperature sensor diagnostics includes a coolant flow sensor configured to provide an indication of coolant flow within a coolant system; an engine state sensor configured to provide an indication of an operational state of an internal combustion engine; and a diagnostic module in communication with the coolant flow sensor and engine state sensor. The diagnostic module is configured to use the indication of coolant flow and the indication of an operational state of the internal combustion engine to estimate an amount of accumulated energy within the internal combustion engine.
