摘要： 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.

摘要： A diagnostic system includes a temperature derivative module and a heater use module. The temperature derivative module determines a derivative of a temperature of one of a fluid of an engine of a vehicle and a component of the engine measured by a temperature sensor after a vehicle startup event. The heater use module selectively indicates that an engine heater was used before the vehicle startup event based on the derivative.

摘要： A system includes a temperature determination module and a flow determination module. The temperature determination module determines an engine coolant temperature based on input received from an engine coolant temperature sensor and determines an engine material temperature based on input received from an engine material temperature sensor. The engine coolant temperature is a temperature of coolant in an engine, and the engine material temperature is a temperature of at least one of an engine block and a cylinder head. The flow determination module selectively determines coolant flow through the engine based on the engine coolant temperature and the engine material temperature.

摘要： A system includes a pump control module and a pump diagnostic module. The pump control module switches a switchable water pump from off to on. The pump diagnostic module diagnoses a fault in the switchable water pump based on a first difference between an engine material temperature and an engine coolant temperature when the switchable water pump is switched from off to on. The engine coolant temperature is a temperature of coolant circulated through an engine and the engine material temperature is a temperature of at least one of an engine block and a cylinder head.

摘要： A method of monitoring an engine coolant system includes modeling the total energy stored within an engine coolant. If an actual temperature of the engine coolant is below a minimum target temperature, the modeled total energy stored within the energy coolant is compared to a maximum stored energy limit to determine if sufficient energy exists within the engine coolant to heat the engine coolant to a temperature equal to or greater than the minimum target temperature. The engine coolant system fails the diagnostic check when the modeled total energy stored within the energy coolant is greater than the maximum stored energy limit, and the minimum target temperature has not been reached.
