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?
thanks all
