An absolute steering angle sensor includes a single main gear having first gear teeth with a first pitch, second gear teeth with a second pitch, wherein the first and second gear pitches are different. A first magnet gear is driven by the first gear teeth, wherein the first magnet gear has a first gear profile and a first diameter. A second magnet gear is driven by the second gear teeth, wherein the second magnet gear has a second gear profile and a second diameter. The first and second gear profiles are different, and the first and second diameters are different. A first magnet rotates with the first magnet gear and emits a first magnetic field, and a second magnet rotates with the second magnet gear and emits a second magnetic field. A sensor assembly measures strengths of the first and second magnetic fields and calculates an absolute steering angle.
