99 Caravan 2.4L - service engine light with code 55??

99 Caravan 2.4L, 38K miles. Service engine light went on. Gas cap was
loose, almost off completely, so I tightened it. I checked the codes
by 1) holding Reset and Trip buttons on odometer, 2) key to ACC, 3)
release buttons after 5 seconds, 4) push Trip button. Odometer flashes
only 55. Is the 99 Caravan 2.4L an old style code, i.e. 55 means "end
of codes"? But the Service Engine light is still on. Is there a fuse
I can pull to reset the PCM and clear the code? I don't have the skill
or guts to disconnect the battery myself.

Thanks much. -R.

It would have to see 2 good trips (start up from cold and reach operating
temp) before the lite will turn off if it was the loose cap.
