PCM code P0440 HC

Anybody have a list of codes handy?
I know the P is for the PCM
H is for History
C is for currant
But I need to know what the P0440 codes is?
Thx,
Tim

That's odd P0440 isn't on the list!
It might be something new for the 03's?
Oh well off to the dealer.
Thanks,
Tim

I had the same code after the car had been standing for 2-weeks while I was on vacation. It's a gas EVAP code and probably just a loose/bad sealing gas tank filler cap.

Ian.

I'll check it out.
The check engine light came on when I stepped on it at a stop sign.
The car had been running for awhile.
Thx,
