If you start at the tank, then the pump will be easy to find. bus or machinery such as cranes), as well as the AdBlue pump. The SCR Catalyst is the last canister of the Aftertreatment system and at the end of it, you will find the NOx OUT sensor.įor the DEF system, the tank location varies depending on application and manufacturer (eg. The NOx IN sensor is located either right after the turbocharger, or at the intake of the aftertreatment system. Engine has been running on non-Ultra-low sulfur Diesel fuel leading to catalyst coating deterioration.Diesel exhaust fluid deposits in the decomposition tube.Typical causes that lead to an active 3582 fault code are: Possible causes of Cummins Fault Code 3582 The ECM compares these two values, which allows it to determine the conversion efficiency of the SCR catalyst and DEF (AdBlue) dosing system. The NOx concentration in the exhaust gases is monitored by two sensors: NOx IN and NOx OUT. How is the SCR Conversion efficiency determined? Once it’s gone inactive, the derate will also go inactive. If the engine has been run with an active Cummins Fault Code 3582, then it is likely that a power derate will also be active (Fault Code 3714 – Engine Protection Torque Derate – Condition Exists).
