A check-engine light turning itself off doesn’t mean the problem fixed itself.
Many faults are intermittent. If the computer stops seeing the problem for enough drive cycles, the warning light may shut off—even though stored codes and diagnostic data can still provide clues about what happened.
That information can be especially valuable before codes are cleared or the battery is disconnected.
If your warning light comes and goes, don’t ignore it just because it went away.
