Question

Agency says evap control leak detected code P0456 -
Check engine light comes on and stays on - Cruise Control light flashes on and off at a steady pace

Answer 1

Hi there,

You need to have a smoke test performed to find the leak. The cruise light flashing is normal when the check engine light comes on. Subaru disables the cruise control as a safety measure. When the evap leak is repaired the check engine light will go out and then the cruise will also start working again.
