Refer to section "Removal of the Intake Manifold AirTemperature Sensor" .b.No; Go to step 5.5.Disconnect the intake manifold temperature sensor harness.6.Inspect the intake manifold temperature sensor harness connector for bent, spread or corroded pins.a.If pin damage is found, replace the intake manifold temperature sensor harness connector and intake manifoldtemperature sensor. Refer to section "Removal of the Intake Manifold Air Temperature Sensor" .b.If no pin damage is found, Go to step 7.7.Compare intake manifold pressure to atmospheric (Baro) pressure. Is the intake manifold pressure within 0.4 psi of Baropressure?a.Yes; Go to step 8.b.No; replace the intake manifold pressure sensor. Refer to section "Removal of the Intake Pressure/TemperatureSensor" .8.Monitor the Exhaust Gas Recirculation (EGR) delta P voltage (pin 109).

The vehicle must be parked outside.16.Perform a High Idle Regeneration. Retain the log file and contact the Customer Support Center for further analysis anddiagnostic information. Refer to section "Performing a Parked Regeneration Using DDDL".

Run to the checks listed above as this could be a faulty differential pressure sensor or manifold sensor, as well as potential leaks within the charge air cooler and problems with the EGR system as mentioned above. You'll need to run through those checks in order to isolate and rule out each of these possibilities. 

I hope you find this information helpful. Reply back with the results of these checks if any further help is needed. It's a pleasure to help anyway I can.
