A method of correcting a crankshaft position may include determining first, second, and third crankshaft positions, determining first, second, and third cylinder pressures, determining first, second, and third cylinder volumes, determining the logarithm of the first, second, and third cylinder pressures and cylinder volumes, and determining a relationship between the third cylinder volume and the first and second cylinder volumes. The first, second, and third crankshaft positions may be provided during one of a piston expansion stroke and a piston compression stroke within a cylinder. The logarithm of the third cylinder pressure and cylinder volume may be evaluated with respect to a predetermined limit of a line defined by the logarithm of the first and second cylinder pressures and first and second cylinder volumes.
