New gas cap.

Outside temperature can affect almost anything electronic or mechanical. Check the gas cap first then move on to the Evap system.

The evap system diagnostic is only enabled at ambient temperatures of 40F or above. If a component went bad over the winter, it could just now be showing up due to warmer weather.
