  The thermonuclear rate of the $^{42}$Ti($p$,$\gamma$)$^{43}$V reaction has
been reevaluated based on a recent precise proton separation energy measurement
of $S_p$($^{43}$V)=83$\pm$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 between A$\approx$40--45. As well, the precision
of the recent experimental $S_p$ value constrains these yields to better than a
factor of three.
