Ok so I know there’s been some threads on the p0100 and U0106 codes but I’ve tried everything that has been mentioned and still no luck. Truck is ******d and none on the nox sensors are plugged in but when I checked the nox modules the front one was full of crap and had some burn marks so I replaced the front module with a brand new one from Ford and checked the rear module and it’s bone dry and looks good. The #36 fuse wasn’t blow but I replaced it anyways just to be sure and I still have the CEL and as soon as I clear it it comes back. I checked all the wiring to the modules and nothing looks burnt or chewed or out of place. Any help would be greatly appreciated.
