I had that same code once. After about 100 miles it went away. I don't know what happened. I do know that two months later my check engine light came back on with another code, this time it was a bad EGR valve.

I would disconnect the battery to clear the codes and see if it comes back. Let me know if the EGR code shows up soon too. This purge solenoid circuit code may be a prelude to the EGR code in some way. :confused:
