A method is described of controlling ignition timing of an internal combustion engine when an abnormality develops in a system for sensing a reference crank angle position of a crankshaft of the engine, in which the timing at which an ignition coil starts and stops conducting is controlled on the basis of a first pulse signal generated once per at least two revolutions of the crankshaft at a predetermined crank angle position associated with a particular cylinder of the engine, a second pulse signal indicative of a predetermined reference crank angle position of the crankshaft for each cylinder, and a third pulse signal indicative of predetermined angular positions of the crankshaft.
