Abstract
A method and control module includes a manifold absolute pressure comparison module that determines a function of the manifold absolute pressure and an average manifold absolute pressure for a plurality of cylinders and that compares the manifold absolute pressure parameter to a manifold absolute pressure threshold. The control module includes a misfire event module that compares the misfire parameter to a misfire threshold. A hardware remedy module performs a valve actuation hardware remedy in response to comparing the manifold absolute pressure and comparing the misfire parameter.
