Fault code question

[DC Jeff]

I have a quick question: I recently replaced plugs and tubes and left one of the coils unplugged resulting in a check engine light. Found the loose wire and all is good now but will this check engine light go away on its own or do I have to have someone clear it?
Thanks in advance for the help

It will eventually go out on its own.
