The thermonuclear rate of the $^{42}\mathrm{Ti}$(${p,\ensuremath{\gamma})}^{43}$V reaction has been reevaluated based on a recent precise proton separation energy measurement of ${S}_{p}{(}^{43}\mathrm{V})=83\ifmmode\pm\else\textpm\fi{}43$ keV. The astrophysical impact of our new rates has been investigated through one-zone postprocessing type-I x-ray burst calculations. It shows that the new experimental value of ${S}_{p}$ significantly affects the yields of species for $A\ensuremath{\approx}40$--45. As well, the precision of the recent experimental ${S}_{p}$ value constrains these yields to better than a factor of 3.
