Take it to a factory Cummins shop and get warranty work done. They’ll do it right.
Opendeckin, Siinman, ducnut and 2 others Thank this. -
Take it to Kenworth...they'll fix it
-
First thing first! make a Cummins QuickServe Online account and add your ESN in then go to fault code search and put all 3 codes in. It will tell you what code to start with. More then likely code 1142 is the one causing all the other ones. Could be a bad injector to a bad return line to a bad wiring harness.

We checked the injector and harness and they’re good. So it’s giving us a head scratching moment lol. -
If its a dealer they should be following the 4 steps in the repair tree.Siinman Thanks this.
-
Well we have abd everything checks out so that’s why I’m asking
-
Are you running any after market sensors?
-
What shop are you taking it to?
A third party shop or a dealer or a cummins owned shop?Siinman and Midwest Trucker Thank this. -
