Silicon isotopic ratios measured in meteoritic presolar grains can provide useful information about the nucleosynthesis origin of these isotopes if the rates of nuclear reactions responsible for their production are known. One of the key reactions determining the Si isotopic abundances is Si(p,)P. Its reaction rate is not known with sufficient precision due in part to some ambiguous resonance strength values. In the present work, the strength of the 
= 416.9 keV resonance has been measured with high precision using the activation technique. The new strength of 
16 meV can be used in updated reaction rate estimations and astrophysical models.
