No the ECU can't tell.

Yes mate, It can still happen, if the passages in the air box in front of the throttle bodies, are blocked with goo. This is the passages that connect the two cam cover breathers to the Ventilation valve.
If you look at where the two breather pipes enter the box, it looks like they just go straight in, but they both go into a small passage that connects through a restriction to the PCV valve.
These are where the engine flows the crank case pressure, under full throttle as the PCV valve is closed then.
I would pull the air box off and clean out the breather passages.
Harvey.
