Publication Date: October 12, 2007
FORD: 2003-2005 Excursion
2003-2007 F-Super Duty
2004-2008 E-350, E-350, E-450, E-450
This article supersedes TSB 06-19-6 to update the Service Procedure.
ISSUE:
Some 2003-2007 F-Super Duty, 2003-2005 Excursion and 2004-2008 E-Series vehicles equipped with a 6.0L engine may exhibit one or more of the following symptoms: lack of power, surge, and malfunction indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P0401, P0402, P0404, and/or P1335.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
Follow normal Powertrain Controls/Emissions Diagnosis (PC/ED) led diagnostics for the symptom or code identified. If normal diagnostics lead to EGR valve inspection and replacement or valve cleaning, replace it with a new EGR valve.
NOTE: NOTE: DO NOT CLEAN THE EGR VALVE.
Remove and replace the EGR valve.
Clear any DTCs and perform the key on engine off (KOEO) On Demand Self-Test to learn the new EGR closed position. Failure to due so could result in a false P0404 DTC.
Verify the repair by using IDS and running the EGR System Test.
If the root cause of the EGR valve replacement was related to coking, the cause must be corrected or the coking may reoccur. Check for TSB's related to coking and the other diesel operating systems that could contribute to coking (fuel, turbo, oil, air induction, vehicle maintenance).
