P1050 - Reductant sensor malfunction

26K views 13 replies 8 participants last post by  wallj77  
I have a 2016 Z71 with about 115k miles. Recently have a P1050 code active, indicating a malfunctioning DEF level sensor and my def level indicates . . Would any of you know the resistance range for this sensor? I'm not worried about the DEF level, I'd rather bypass with a resistor and trick it into thinking the tank is always full. I have the wiring diagram and terminal diagram but cannot find the resistance range anywhere or a test procedure to indicate a full value.

Any help would be greatly appreciated
