Abstract
A method for diagnosing an engine (102) including the steps of sensing a first set of parameters of the engine (102) and determining a modeled value of a first operating characteristic. A second set of parameters of the engine (102) is sensed and used to determined a modeled value of a second operating characteristic. The modeled values are compared to actual values and the engine is responsively diagnosed.
