    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.

    摘要： A diagnostic system for an engine includes a stage transition module and a control module. The stage transition module generates a command signal based on a fuel control signal. The command signal commands a fuel system of the engine to intrusively transition between rich and lean states during a diagnostic test that includes first, second, and third stages. The first, second, and third stages are defined based on transitions between the rich and lean states. The control module during the second and third stages detects: an error with a first oxygen sensor based on a comparison between the command signal and a first oxygen signal from the first oxygen sensor; an error with a second oxygen sensor based on a second oxygen signal from the second oxygen sensor; and an error with a catalytic converter based on the first and second oxygen signals and a manifold absolute pressure signal.

    摘要： A temperature comparison module generates a temperature difference between an engine coolant temperature and a radiator coolant temperature. An energy determination module determines an energy value corresponding to heat energy generated by an engine. The heat energy increases at least one of the engine coolant temperature and the radiator coolant temperature. A diagnostic module generates a comparison of the temperature difference and the energy value and determines a status of a thermostat associated with the engine based on the comparison.
