Lots of Crankcase Vent Sensor or Electronic Throttle Fails???

Came across this while looking for a 3UR powercurve diagram. I do not really believe these 2 items fail much mostly because I have not read much about them.

So do we think this is garbage BS or truth (here is brief article - read down to Problems & Reliability section?

Honestly never heard about either failing on here

 

I worked for Toyota off and on from 2007-2017 as a tech. I've never seen any issues with the PCV system whatsoever, besides rodents damaging hoses. They love to nest in the valley of the engine, on top of the PCV system. Here's a pic of the mouse nest my brother found when resealing my valley plate. Attached to this issue, it is very common for rodents to also attack the knock sensor wiring.
