Archived check engine light, low apps voltage

[RBassetti]

my 2001, check engine light came on during a road trip, stopped once and the light remained on when I started again. the next day the light was out. code was 0122 low voltage on apps. its been a week now. whats up with the light going out?

After 3-4 starts if the code isn't set the light will reset itself.
