Different years/engines/models have different fuel injection systems, and those different systems have different fault storage mechanisms. Depending on the system, even if the problem goes away, it may take a system reset to clear the fault. In other systems, just not having the fault (depending on which fault it is) may go away by itself, but it could take 30 engine starts.
The cheapest approach is to clear the fault. If it comes back, you've still got an issue. If it's gone, then assume it's gone. But we need to know the system to know how to clear it.
