Abstract

Methods are provided for holding an engine steady during a drive cycle to complete one or more diagnostic routines. The engine may be held steady while an operator torque demand varies if a sufficient number of diagnostic routines need to be completed and are enabled for completion. By holding the engine steady, an accuracy and completion of the diagnostic routines is improved.
