Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 1925 PID: SID 334 SPN: 3482 FMI: 2 Aftertreatment Fuel Shutoff Valve 1 – Data Erratic, Intermittent, or Incorrect
Posted by PerDiezel Solutions on
Circuit DescriptionBefore active regeneration of the aftertreatment diesel particulate filter, a diagnostic test on the system is performed. The aftertreatment fuel injector opens and relieves fuel pressure in the line. The aftertreatment fuel pressure sensor must be reading atmospheric pressure at this point in the test. The aftertreatment fuel injector closes and the aftertreatment purge air actuator opens. This pressurizes the aftertreatment fuel system to vehicle air pressure. The diagnostic then checks to make sure the aftertreatment fuel pressure sensor is reading vehicle air pressure. The aftertreatment fuel shutoff valve then opens and allows pressurized fuel to enter the system....
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 1926 PID: SID 332 SPN: 3480 FMI: 2 Aftertreatment Fuel Pressure Sensor- Data Erratic, Intermittent, or Incorrect
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment fuel pressure sensor is used to monitor the fuel pressure into the aftertreatment system. The engine control module (ECM) supplies the aftertreatment fuel pressure sensor a 5 volt reference voltage. When the fuel pressure is low, the sensor signal voltage is low. When the fuel pressure is high, the sensor signal voltage is near the 5 volt reference voltage. The ECM monitors the aftertreatment fuel pressure signal circuit voltage to calculate the pressure of the fuel within the aftertreatment system. Component LocationThe aftertreatment fuel injector is installed in the exhaust system in the turbocharger adapter pipe. The...
