We study the CP violation induced by the interference between two intermediate resonances K⁎(892)+ and K⁎(892)- in the phase space of singly-Cabibbo-suppressed decay D0→K+K-π0. We adopt the factorization-assisted topological approach in dealing with the decay amplitudes of D0→K±K⁎(892)∓. The CP asymmetries of two-body decays are predicted to be very tiny, which are (-1.27±0.25)×10-5 and (3.86±0.26)×10-5, respectively, for D0→K+K⁎(892)- and D0→K-K⁎(892)+, while the differential CP asymmetry of D0→K+K-π0 is enhanced because of the interference between the two intermediate resonances, which can reach as large as 3×10-4. For some NPs which have considerable impacts on the chromomagnetic dipole operator O8g, the global CP asymmetries of D0→K+K⁎(892)- and D0→K-K⁎(892)+ can be then increased to (0.56±0.08)×10-3 and (-0.50±0.04)×10-3, respectively. The regional CP asymmetry in the overlapped region of the phase space can be as large as (1.3±0.3)×10-3. [ABSTRACT FROM AUTHOR]
