Heres a TSB about it:

Subject: LBZ LLY Engine with Rough Idle, Poor Performance, Black/White Exhaust Smoke, MIL/SES Light On, DTCs P003A, P060B, P0230, P0403, P0401, P0606, P2146, P2149, P2152, P2155 (Reprogram ECM) #06-06-04-066A - (03/09/2007)



Models: 2006-2007 Chevrolet Express, Kodiak C4500/C5500 Series, Silverado Classic

2006-2007 GMC Savana, Sierra Classic, TopKick C4500/C5500 Series

with 6.6L Duramax ™ Diesel Engine (VINs D, 2 -- RPOs LBZ, LLY)




--------------------------------------------------------------------------------

This bulletin is being revised to add additional warranty information on the EGR learn procedure. Please discard Corporate Bulletin Number 06-06-04-066 (Section 06 -- Engine/Propulsion System).


--------------------------------------------------------------------------------

Condition
Some customers may comment on an illumination of the MIL/SES with one or more of the following symptoms:

• Rough Idle

• Poor Performance

• Black/White Exhaust Smoke

Upon further investigation, the technician may find one or more of the following DTCs stored in the ECM:

• P003A: Turbocharger Boost Control Position Not Learned

• P060B: Control Module Analog To Digital Performance

• P0230: Fuel Pump Relay Control Circuit

• P0403: EGR Solenoid Control Circuit

• P0401: Exhaust Gas Recirculation Flow Is Insufficient

• P0606: Control Module Internal Performance

• P2146, P2149, P2152, P2155: Injector Positive Voltage Control Circuit Group 1-4

Cause
This condition may be caused by a calibration issue.

Correction
Important: If the calibration update was for DTC P0403, then follow the service procedure in this bulletin to ensure that the P0403 code has been eliminated.

If routine diagnosis using SI does not reveal any obvious cause for the DTCs setting, then reprogram the ECM.

Reprogram the ECM with the latest calibrations if the above concern is encountered. An updated ECM calibration is now available to address this concern. This calibration, or any that follow, is designed to address this concern.

The new ECM calibration is available to dealerships in TIS2WEB (website version of TIS) version. If you cannot access the calibration, please call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided. As always, make sure your Tech 2 is updated with the latest software version.

P0403 EGR SOLENOID CONTROL CIRCUIT LEARN PROCEDURE
After the new calibration is installed for a DTC P0403, the EGR valve learn procedure should be performed four times before returning the vehicle to the customer. The EGR learning cycle occurs on engine shutdown. Technicians should perform the following service procedure to ensure that the DTC P0403 has been eliminated:

Start the engine. Let the engine idle until the engine coolant temperature is greater than 75C (167F). Then shut the engine off for one minute.
Once the engine coolant temperature is greater than 75C (167F), repeat this procedure four separate times, letting the vehicle idle for 30 seconds.
Evaluate the vehicle performance and EGR operation after the learning cycle has been completed.
