The code popped up again with the NOX outlet sensor code and then we replaced the Outlet NOX sensor located in the exhaust. After the truck ran for a few hours then a bunch of codes came back on SPN 4340, 4342, 4344, 4094, 4364, 1569 ….

Long story short, these fault codes mean that the efficiency in the aftertreatment system, aka the 1-Box, is not operating within the required threshold (70%).
The most common way to reduce diesel engine NOx out emissions is to use SCR. SCR operates by injecting aqueous Urea solution, 32.5% by volume (AUS-32), that evaporates prior the catalytic surface of the SCR-catalyst. Due to a catalytic reaction within the catalyst, NOx is converted nominally into Nitrogen and Water.• AS018 Selective Catalyst Reduction (SCR) Inlet Temperature • AS019 SCR Outlet Temperature • AS035 SCR Inlet NOx sensor • AS036 SCR Outlet NOx sensor • AS101 NOx Conversion Efficiency WARNING: ENGINE EXHAUST To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is …However, SCR efficiency can be less than 100% at low temperatures in general, and at higher temperatures with high exhaust SCR catalyst space velocities. At the low temperatures where NO x conversion efficiency is low, it may be advantageous to reduce the alpha ratio to values less than one (less NH 3 than is needed to convert …
