Default Diagnostic Trouble Codes

First, let me say that with respect to being uninformed by any diagnostic tool, my vehicle has performed flawlessly since I took possession 26 months ago. No service problems, no performance issues, and certainly no CELs or MILs. I was blissfully happy.

So, motivated by curiosity and boredom, I finally used my OBD11 tool on the vehicle for a full-body scan. It produced the following eight (8) DTCs. I used the URL following to try to understand the meaning of the codes; only three of them had matches.

I don't really know how to interpret the significance or severity of the log, other than I'm glad that all of them are labeled "intermittent". Can anyone advise me as to how to interpret the results and what to do next?

Thanks in advance.

I recognize/had a few of those codes, just "clear" them out with OBD11 and you're good to go, nothing to worry about. If I connected my OBD11 right now, I'm sure I would get some extraneous codes too.

As synergize said - clear them out.
However, if the code/s keep coming back then worry about it.
