Cummins ISB4.5 CM2150 Fault Code: 357 PID: 132 SPN: 132 FMI: 4 Engine Intake Air Mass Flow Circuit – Voltage Below Normal or Shorted to Low Source.
Posted by PerDiezel Solutions on
Circuit DescriptionThe mass air flow sensor is a frequency based device. A constant voltage is applied to a heated wire. This wire is positioned in the air stream and is heated by the electrical current that the voltage produces. As air flows across it, it cools down. The heated wire or film is a positive temperature coefficient (ptc) resistor. This means that the resistance drops when the temperature drops. The drop in resistance allows more current to flow through it in order to maintain the programmed temperature. This current is changed to a frequency which is sent to the ECM...
Cummins ISB4.5 CM2150 Fault Code: 3571 PID: SPN: 4334 FMI: 3 Aftertreatment Diesel Exhaust Fluid Pressure Sensor – Voltage Above Normal or Shorted to High Source.
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment diesel exhaust fluid controller provides a 5 volt supply and a ground to the aftertreatment diesel exhaust fluid pressure sensor. The pressure sensor provides a signal to the aftertreatment diesel exhaust fluid controller on the sensor signal circuit. This sensor signal voltage changes, based on the aftertreatment diesel exhaust fluid pressure supplied by the dosing unit. The afterteatment diesel exhaust fluid controller 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...
