I got the same problem on my 99 V70XC that I'm trying to track down without paying the dealer $100 to diagnose the problem. Any luck so far?

I wouldn't be surprised if that error code resulted from not having the gas cap on tight enough temporarily compromising the closed evaporative control system.
