Previously posted re: Cummins engine check light - discovered code: SPN 4364 FMI 18 SA 0. After replacing those parts the SCR conversion code popped up only and then we replaced the Inlet NOX sensor. 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, 1569Monitor the NOx conversion efficiency. Is the NOx conversion efficiency above 85%? a. Yes; this fault was likely caused by the DEF build-up in the exhaust which was cleared by the parked regeneration procedures. Perform a Parked SCR Efficiency Test to clear the regulatory fault. Refer to section "GHG17 Perform Parked SCR Efficiency Test".

FMI 18. FMI 31. Code Description: Aftertreatment SCR Catalyst Conversion Efficiency data valid but below normal operating range - moderately severe level. Best case scenario: Do a forced Regen and be on your way. If the Code comes back: if the code reappears you will need to consider getting DPF filter changed or getting it cleaned.Monitored Parameter NOx Conversion Efficiency Typical Enabling Conditions Closed Loop DEF Dosing Monitor Sequence None Execution Frequency Always Enabled Typical Duration Two Seconds Dash Lamps MIL Engine Reaction None Verification Parked SCR Efficiency Test Check as follows: 1.

4364 1 fault occurs when the outlet Nox is higher than expected. This is, be caused by either a faulty Nox sensor or poor quality DEF contaminating the system and potentially causing problems or failure with your scr and after treatment components. I would start with a replacement sensor as that is a common cause.Selective Catalyst Reduction NOx Conversion Very Low. Table 1. SPN 4364/FMI 1. SPN 4364/FMI 1. Description.
