ABSTRACT:
A method and code for controlling the operation of a deactivatable valve lifter of an internal combustion engine includes determining an oil viscosity measure based upon an engine oil pressure achieved when the engine is operating at a warm engine idle operating condition; determining a minimum oil temperature for actuator operation based on a comparison of the oil viscosity measure with a stored value representing the oil's nominal viscosity; and enabling actuator operation when an instantaneous oil temperature is not less than the minimum oil temperature.
