The three-body resonance of K̄NN system is investigated by using the K̄NN - π YN coupled channels Faddeev equation. The resonance energy is determined from the pole of S-matrix on the unphysical sheet. It is found that the pole positions of the predicted amplitudes are significantly modified when the three-body dynamics is approximately treated by introducing the effective K̄N two-body interaction.
