I have a 2007 Boxster. The CEL comes on often. It produces a p456 code
which is usually the gas cap. I have replaced the gas months ago and the light still comes on frequently. Does anyone know of another solution to the Annoying CEL. I have a feeling it has something to do with a valve/ flap on the gas tank refill neck, __________________ This post was auto-generated based upon a question asked on our tech article page here: Porsche Boxster Fuel Injection Fault Code Reading / Diagnosing Problems - 986 / 987 (1997-08) - Pelican Parts Technical Article |

This could be a faulty solenoid or hose. When the system is tested for evap leaks, a small one in present. I suggest smoke testing the system
