Using 2.7 fb{sup {minus}1} of data taken with the CLEO II detector, we have searched for {ital CP} violation in the charm system. We looked for asymmetries in the number of decays of {ital D}{sup 0}`s and {ital {bar D}}{sup 0}`s to the {ital CP} eigenstates {ital K}{sup +}{ital K}{sup {minus}}, {ital K}{sub {ital S}}{sup 0}{phi}, and {ital K}{sub {ital S}}{sup 0}{pi}{sup 0}. Confidence intervals (90%) on these asymmetries were found to be {minus}0.020{lt}{ital A}{sub {ital K}{ital K}}{lt}0.180, {minus}0.182{lt}{ital A}{sub {ital K}{ital S}}{sup 0}{phi}{lt}0.126, and {minus}0.067{lt}{ital A}{sub {ital K}{ital S}}{sup 0}{pi}{sup 0}{lt}0.031, respectively.
