Slide under the car, and look up, at the rear of the passenger side below the trunk and right below the fuel tank filler-neck where you add gasoline. There is a black plastic box, a little smaller than a shoe box. Unlatch the bottom-cover by sliding the little button-ears under the latches. Look for the solenoid, which will look like an iron core with a lot of copper wires wound around it. Unclip the solenoid and the wires. Pop off the front end of the solenoid, clean the o-ring with alcohol, and lightly regrease the o-ring with di-lectric grease or vasoline jelly. Re-install everything and clear the codes. This worked for me. My trouble code was something like "small leak at the evap purge valve." That was 50,000 miles ago and it has not returned.
