PROBABLE CAUSES:
1. failed intake manifold temperature sensor.
2. Intake manifold temperature sensor connector/harness.
3. EGR delta P sensor.
4. EGR delta P sensor connector/harness.
5. EGR system leaks (Check for soot).
6. Remove the DPF and check for blockage or contamination (Coolant, fuel, oil, etc…).
7. Check the entire exhaust system (including the EGR) for leaks.
8. Perform stationary regen.
