Claim 0:
1. A controller for controlling an engine having a plurality of cylinders, each cylinder having an associated intake valve and an associated exhaust valve, wherein the controller is configured to:
detect an exhaust valve actuation fault for a first exhaust valve of the exhaust valves during a first working cycle, the first exhaust valve being associated with a first cylinder;
in response to the detection of the exhaust valve actuation fault, direct fueling to be cut off to at least the first cylinder;
direct an attempt to actuate the first exhaust valve in a set of one or more engine cycles that follows the first working cycle, wherein the first cylinder is not fueled during the set of one or more engine cycles;
direct an electric motor to maintain at least one of a desired drive torque and a desired crankshaft rotation speed during the set of one or more engine cycles; and
determine whether to resume operation of the first cylinder based at least in part on whether at least some of the attempts to actuate the first exhaust valve in the set of one or more engine cycles are successful.
