Ok so not true DTCs?

The CEL went away on its own.

Hi following up on this - what do you guys think?

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.

Before CEL cleared
After CEL cleared

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 ...
