Just wanted to let everyone know what the real problem was. Here is my husband's description of solution to problem. Everyone was real helpful in this forum.

The code showed a problem with the Evaporative Emission Canister Vent
Solenoid Valve. Removed the canister (under the driver's seat), tested the
SV, it was OK. Tested the harness between the SV and the large bulkhead
connector that's about under the passenger's seat behind the driver and
found one wire to be Open. Note, this testing should be done with a test
light or something OTHER than a voltmeter. Pulled the wires out of the split
plastic sheath and found that one had had the insulation nicked and the wire
corroded in two. Spliced 'er back together, reset the code, and all was
well.

I can't imagine that this problem would appear in any other vehicle, as it
is most probably a one-time thing. The wire could even have gotten a minor
nick at the wire manufacturer's, before reaching Delphi or whoever. The
plastic sheath was not damaged in any way.

While under the car, I removed several largish stones from between the
straps and the plastic fuel tank.

Thanks,
