at higher engine speeds, you will notice it smooths out, but is still active.

what is your time frame in that capture? it looks fairly long, i"m guessing around 30-60 seconds?

I am still collecting data on this fault code, thank you cure12 very good info here.

Capture is about 20 seconds or so. Car had been run for about 40 min before taking the log. I've got about 125 miles on it so far and no CEL.
