DEF Sensor Issues

Vanlieremead · 2021-08-17T03:41:42+0000

Has any experienced derate issues of the current Duramax diesel due to DEF sensor issues? With other makes, it's a big issue with derates to 5% when the sensor fails regardless of tank level.

  Should probably post this here too. This tells you what engines you can get with each trim. Certain engines again won't be available depending on trim. Like no 6.6 V8 in the Trail Boss for example. https://gmauthority.com/blog/2026/08/heres-2027-chevy-silverado-engine-availability-by-trim-level/
- AUX switch install

  Hello, wondering if anyone can help me with this little problem. I was trying to order the Upfitter Switch that has TC, Cargo Light, Blank, Aux 1-4.... Order was cancelled due to "not having it". The only available option to me now is the Upfitter Switch that has all these options, but in the blank space there is "Exhaust Braking". My truck is a gasser, so this is of no use to me. I need to find where Pin 4 and Pin 5 of the X2 connector run to (i.e X61A - X1 - Pins X & Y), and manipulate that somehow to get my desired outcome. Has anyone done this? Would there be any implications with me just doing nothing with it and installing it as is and never using it? I have gathered that it is "momentary" - so there are some considerations there. Please help!
