This doesn't seem to be a fuel system problem..

I replaced the purge solenoid. It is difficult to examine closely the wires and hoses due to where the valve is located. But as best as I can tell they appear to be OK. I replaced the gas cap thinking the seal might be bad, allowing the vapors to be released. I still get the error code. Because our temperature has dropped greatly here in Minnesota, I can not tell if the cap solved the gas smell problem. I don't notice it now.
