PCM throwing P0440 on DIC
I regularly run through diagnostics on my C5 to catch any issues as soon as they arise. I've been on vacation for 2-weeks (during which time the car was not driven). When I returned, I started it up and the DIC threw a P0440 code.
According to the generic OBDII data I have, this is a fuel EVAP issue(?)
The car drives fine... any ideas what is causing this?
Cheers,
Ian.

Could be somthing as simple as the seal on the gas cap "leaking" a small amount of air over that time period. Clear the code and see if it comes back. Make sure the cap is on good and tight. :)
