Low diesel exhaust fluid pressure has been detected in the dosing unit.I think this month’s case study will have HD techs very interested. As everyone knows Diesel Exhaust Fluid (DEF) Pumps are now in use on every aftertreatment system out there today on the modern heavy-duty vehicle. They are used to supply pressurized fluid to the doser injector, so it can deliver the fluid in an atomized spray into …The DPF is an exhaust device that traps particulate matter such as soot and ash. How it works: Unlike the DOC, which is designed to be flow-through, the DPF is a wall-flow which means the exhaust flows into the filter through pores, and the soot and ash collect on the walls of the filter. The DPF has two jobs, catch soot and store ash.

If no fault comes up, then the problem has been solved. If you see the 520363 fault code along with the SPN 3223 FMI 7 code, then that means "Selective Catalyst Reduction Inlet NOx Sensor Circuit Failed Open.”.

The inlet sensor measures the nitrogen oxide (NOx) levels in the exhaust before it passes through the SCR and reports this data to the ECU. Based on this, the ECU determines how much DEF the doser should inject into the exhaust gas.
