Disclosed is a camshaft toothed wheel, forming a target for a camshaft position sensor, the toothed wheel including a circular body including two opposite main faces, and at least six teeth distributed over the circumference of the circular body, each tooth including two edges, one corresponding to a rising edge and the other to a falling edge, as a function of a direction of rotation of the wheel, the toothed wheel having asymmetry of revolution. The six teeth are shaped so that the toothed wheel includes, considering the same main face and the same direction of rotation of the wheel: four edges of the same first rising or falling type spaced 90° apart, respectively; and six edges of the same second falling or rising type, respectively, spaced 60° apart, respectively.
