Scr nox conversion efficiency low 4364
Ya, it’s a catch all code for low NOx efficiency. It can be just about anything. I’ve had it since winter, mostly first thing on a Monday morning. I have Detroit Diesel Diagnostic Link, so I can eliminate some of the steps without going to the dealer. One of the early steps it said to replace the outlet NOx sensor as it was reading low.very common problem with the detroits, often in stationary burn with pass efficiency test just fine. you can force a burn and monitor or log your nox conversion + input output values, ADS pump speed and DEF pressure as well as pump demand in g/h, depending on how the graph develops you can check for nox sensor drift.
