Abstract

See full text

Methods and systems for diagnosing operation of an exhaust gas recirculation system of an internal combustion engine are described. In one example, the EGR system is diagnosed while an engine that includes the EGR system is not rotating and combusting fuel. The EGR system is diagnosed when the engine is not operating so that vehicle passengers are not disturbed by the diagnostic and so that flow estimates through the EGR system may not be disturbed by pressure changes that may be related to combustion within the engine.
