Using the 9fb-1 data sample collected with the CLEO II.V detector at the Cornell Electron Storage Ring, we study the resonant substructure of the Cabibbo suppressed decay D0 → π-π+π0. We observe significant contributions from the ρ-π+, ρ+π-, ρ0π0, and non-resonant channels, and present preliminary results of the amplitudes, phases, and fit fractions for these sub-modes. No significant evidence for the σ(500) or any other heavy resonance was found. The preliminary measurement of ACP is consistent with 0 at 0.01{ - 0.07}{ + 0.09} ± 0.09 .
