By comparing the Q-values for the ~(46)Ti (~3He, t)46V and ~(47)Ti (~3He, t)47V reactions to the isobaric analogue states the Q-value for the superallowed Fermi decay of 46V has been determined as QEC(~(46)V) = (7052.11 ± 0.27) keV. The result is compatible with the values from two recent direct mass measurements but is at variance with the previously most precise reaction Q-value. As additional input quantity we have determined the neutron separation energy Sn(~(47)Ti) = (8880.51 ± 0.25) keV.
