Hi,
After I did a valve adjustment I had a CEL related to emissions (per rdx screen below speedometer). I plugged flashpro into laptop and started datalogging. No error codes came up, and when I went to the obdii window, it showed a CEL and 3 DTCs, but again no codes.
The CEL has since gone away (after driving 30 miles or so and starting car approx 5 times) but it still shows that I have 3 DTCs without showing any codes.
I have screenshots on my laptop at home that I can upload later.
Any idea what's going on here? Thanks

Have you looked at the error codes window?
Re: DTC codes not showing
Yes the error codes window is blank as well. The second attachment didn't load - I'll reupload it. The window can be seen in that screenshot.

Hi following up on this - what do you guys think?
Re: DTC codes not showing
The CEL went away on its own.

I think it is a fault with the way Honda reports stored error codes using mode 3 (DTCs) and mode 7 (stored DTCs) where the counter shows errors but none are returned.

Ok so not true DTCs?
