Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 3571 PID: SPN: 4334 FMI: 3 Aftertreatment 1 Diesel Exhaust Fluid Pressure Sensor Circuit- Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Circuit DescriptionThe Engine Control Module (ECM) provides a 5 volt supply and a ground to the aftertreatment diesel exhaust fluid pressure sensor. The pressure sensor provides a signal to the ECM on the sensor signal circuit. This sensor signal voltage changes, based on the aftertreatment diesel exhaust fluid pressure supplied by the dosing unit. The ECM will detect a low signal voltage at low diesel exhaust fluid pressures, and a high signal voltage at high diesel exhaust fluid pressures. Component LocationThe aftertreatment diesel exhaust fluid pressure sensor is internal to the aftertreatment diesel exhaust fluid dosing unit and can not...

Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment diesel exhaust fluid return valve is controlled by the Engine Control Module (ECM). The return valve position determines where diesel exhaust fluid will flow as it exits the dosing unit. When the return valve is activated, the dosing system will purge and return the diesel exhaust fluid in the lines to the tank. Component LocationThe aftertreatment diesel exhaust fluid return valve is internal to the aftertreatment diesel exhaust fluid dosing unit and can not be serviced separately. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position or when the engine...
