Abstract
A method for determining the angular position of an internal combustion engine throughout an engine cycle, the method includes the steps of providing a crankshaft having a plurality of teeth, the crankshaft completing two revolutions per engine cycle. A camshaft is provided having a plurality of teeth, the camshaft completing one revolution per engine cycle. An engine controller is provided. A sample size of the engine cycle is set in each of two concurrent engine cycles. The teeth of the plurality of teeth are counted on the camshaft found in the sample sizes. The crank position is then determined according to the teeth appearing in the sample sizes.
