If you replaced the sensor and still have the fault after all wiring was checked . You may need to recalibrate the ECM to the latest revision. You will need someone with or a shop with Cummins insite pro to update the ECM calibration and monitor the sensors actions. I have had to recalibrate hundreds of engines after installing and pulling my hair out over this fault. 75% of the time the sensor reads correct. 25% of the time the ecm needs to be updated AFTER new sensor is installed.

They can also check the EGR cooler for plugging . Its a far shot for the cause but it is a possibility. due to excessive idle time... Just a FYI
