Why is it so hard to Get a sensor for 2019 2500 duramax.To be self employed and needing your truck.Its just bad news all around.

I’ve never had an issue getting either one from the dealer. Rockauto shows they have the upstream is that’s what you need.

Are we talking Knock sensors or Oxygen sensors?

Ironically, nox sensors are almost identical to oxygen sensors and the nox sensor on a Dmax will read oxygen levels like a gasser (l5p will, if have not looked to see if the lml will)
