Reading the shop manual Evaporative Emissions section 25-15, it looks like the EVAP purge solenoid is not working and the excess pressure is discharged via the filler cap. This purging would be a cause to fail any emissions test as you know. The code is kept on record, hence the engine light stays on.
See page 25-15 for a diagram of the Evaporation Control system.
The following is the full description of this fault.

I am no expert by any means but it is always interesting to look at possible causes of problems.
