Cummins ISL CM850 (2003-06) Fault Code: 2271 PID: 27 SPN: 27 FMI: 3 Exhaust Gas Recirculation (EGR) Valve Position Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at the EGR valve position sensor circuit. The EGR valve position sensor shares Supply and Return wires in the engine harness with other sensors. Open circuits and short circuits in the engine harness can cause multiple fault codes to be active. Possible causes: 1)Open return in the harness, connectors, or sensor2)SIGNAL wire shorted to sensor supply or battery voltage3)Failed EGR valve position sensor4)Failed ECM. Possible repairs:...

Cummins ISL CM850 (2003-06) Fault Code: 2272 PID: 27 SPN: 27 FMI: 4 Exhaust Gas Recirculation (EGR) valve position circuit – voltage below normal or shorted to low source. Low signal voltage detected at the EGR valve position sensor circuit. The EGR valve position sensor shares SUPPLY and RETURN wires in the engine harness with other sensors. Open circuits and short circuits in the engine harness can cause multiple fault codes to be active. Possible causes: 1)SIGNAL circuit open or shorted to ground2)SUPPLY circuit open or shorted to ground3)Sensor shorted to ground. Possible repairs: 1)Replace the EGR valve assembly.2)Repair or...

Cummins ISL CM850 (2003-06) Fault Code: 2273 PID: 411 SPN: 411 FMI: 3 EGR valve differential pressure sensor circuit – shorted high. High voltage detected on the EGR differential pressure sensor circuit. The EGR differential pressure sensor shares supply and return wires in the engine harness with other sensors. Open circuits and short circuits in the engine harness can cause multiple fault codes to be active. Before troubleshooting Fault Code 2273, check for multiple faults. Possible causes: 1)Open return in the harness, connectors, or sensor2)Signal circuit shorted to sensor supply or battery voltage3)Supply circuit shorted to battery voltage. Possible repairs:...

Cummins ISL CM850 (2003-06) Fault Code: 2274 PID: 411 SPN: 411 FMI: 4 EGR valve differential pressure sensor circuit – shorted low. Low signal voltage detected on the EGR valve differential pressure sensor circuit. The EGR valve differential pressure sensor shares supply and return wires in the engine harness with other sensors. Open circuits and short circuits in the engine harness can cause multiple fault codes to be active. Before troubleshooting Fault Code 2274, check for multiple faults. Possible causes: 1)Open signal circuit in the engine harness, connections, or sensor2)Supply circuit open or shorted to ground3)Sensor shorted to ground. Possible...

Cummins ISL CM850 (2003-06) Fault Code: 2292 PID: SPN: FMI: 16 Fuel Inlet Meter Device – Data Valid but Above Normal Operational Range – Moderately Severe Level. The flow demand is higher than expected. Causes of this fault code include the following: High inlet restriction, plugged fuel filter, low lift pump pressure, low resistance to the electronic fuel control actuator, stuck or restricted electronic fuel control actuator, system return (excessive return flow from the injectors, high-pressure pump, or rail pressure relief valve), or tampering. Fault Code 2292 sets when the ECM commands the electronic fuel control actuator to open more...
