Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM.
Possible causes:
1)EGR motor circuit open circuit
2)Open circuit in the wiring harness
3)Fuel Injector wiring harness shorted to ground, open circuit, or shorted to power supply.
Possible repairs:
1)Replace the EGR valve.
2)Repair or replace the engine harness.
