Update on my brothers LML, He replaced the wrong sensor. Had him swap with the sensor 2 inchs away on the other side of the exhaust from the Def injector, same codes.... but it drove, so he drove it around and the check engine light went off, drives like a bat.
My findings... EGT before the turbo(not #1?), EGT on downpipe, EGT opposite the Def injector(and the harness runs a loopty loo right into one of the connectors on the Def injector!!!), EGT middle of the particle filter, Egt at end of filter. 5 Sensors i counted.
