Method for compensating a reference measurement including a measurement of angular position α and a measurement of time T1 that are simultaneous at the time t1, for an angular position sensor of the type including a toothed wheel, includes the following steps: determination of a first measurement α of corresponding angular position at the moment in time t1 when a reference measurement is desired; triggering of a software acquisition function; substantially simultaneous acquisitions of a second measurement α′ of the angular position and of a measurement T2 of the time by software acquisition at a time t2; estimation of an error ΔT; and calculation of the compensated measurement of time, T1=T2−ΔT. A Sensor for measuring angular position, of the type including a toothed wheel, implementing such a compensation method is described.
