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.
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 sensor
2)Signal circuit shorted to sensor supply or battery voltage
3)Supply circuit shorted to battery voltage.
Possible repairs:
1)Replace the EGR differential pressure sensor.
2)Repair or replace the engine harness.
3)Replace the ECM.
