Single-particle properties of low-lying resonance levels in 14O have been studied efficiently by utilizing a technique of proton elastic resonance scattering with a 13N secondary beam and a thick proton target. The excitation functions for the 13N + p elastic scattering were measured over a wide energy range of ECM = 0.4 - 3.3   MeV and fitted with an R-matrix calculation. A clear assignment of Jπ = 2- has been made for the level at Ex = 6.767 (11)   MeV in 14O for the first time. The excitation functions show a signature of a new 0- level at Ex = 5.71 (2)   MeV with Γ = 400 (100)   keV. The excitation energies and widths of the 14O levels are discussed in conjunction with the spectroscopic structure of A = 14 nuclei with T = 1.
