2008 daf lf 55 with Cummins isb engine adblu fault

hi guys, with the wealth of experience on here, i thought id ask before i went down the rabbit hole…

i have a ablue light on with the following code:

1694 Aftertreatment 1 Outlet NOx Aftertreatment 1 Outlet NOx Sensor - Data erratic, intermittent or incorrect.

is there a common failure i need to look at first before i start tracing harnesses and checking voltages?

The type of truck is immaterial, the codes for the Engine is what matters !!!

If you can borrow a code reader ? You can reset the code, which will terminate the problem. You can also try these remedies as published by ■■■■■■■■

However if the fault reoccurs it may need a Technician.
