Abstract

Various method for operating an engine responsive to transmission shifts under non-fueling conditions are provided. In one example, a method of operating an internal combustion engine comprises deactivating at least one engine cylinder, performing a diagnostic while the at least one engine cylinder is deactivated and while the engine is operating under high load, predicting a transmission shift, and responsive to the predicted transmission shift, reducing engine load below the high load and terminating the diagnostic.
