Check for a vacuum leak.
A vent hose might be cracked making it leak gas.

I had a code 0172 when I picked up my 850 Turbo but after driving it about 1000 miles in one day and fixing a vacuum leak, the code went away. Not sure why.

Sometimes but not all the time.
The vent hose I mean is on the fuel tank.
I will bet there is staining on the side of the fuel tank.
