2023 RAM 2500 NOX sensor 2 replacement instructions

[rauan]

Hi there. I got a code stating my sensor 2 has failed. I checked under the truck to find a location of the sensor and found that there are two sensors next to each other where one of them is NOX and another one is something else. The problem is I can't even reach with my hands to disconnect the electrical connections because they are located on top the exhaust pipe and from the angle I was looking at it I couldn't see how to remove them.

I would appreciate if anyone had experience removing it and can share how to remove without breaking anything.

I checked online and in this forum for prcedure how to swap the sensor, but can't find it for my model. All I found is this drawing with sensor and electrical module placement.

hate to say it, but you have to drop part of that section of pipe to get to them. you'll have to disconnect the pipe just past the scr (so you can push it back) and then the flange after the catalyst (the DEF tank cross-brace). There alot of other connections up there you'll have to disconnect to be able to drop it down to get to those sensors otherwise you'll destroy the harness. Take a look at this vid..

Starts at about the 19min mark.

Any luck changing the down stream nox sensor. I’m about to do it and could use some pointers!
