06-19-6 6.0L - MIL ON - P0401, P0402, P0404, P1335, LACK OF POWER, OR SURGE. EGR VALVE CLEANING PROCEDURE.

Publication Date: September 11, 2006

FORD: 2003-2005 Excursion
2003-2007 F-Super Duty
2004-2006 E-350, E-450


ISSUE:
Some 2003-2007 F-Super Duty, 2003-2005 Excursion and 2004-2006 E-Series vehicles equipped with a 6.0L engine may exhibit one or more of the following symptoms. Malfunction indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P0404, P0401, P0402, P1335, lack of power, or surge.

ACTION:
Follow normal Powertrain Controls/Emissions Diagnosis (PC/ED) led diagnostics for the symptom or code identified. If normal diagnostics lead to replacement of the EGR valve, use the following Service Procedure to clean the valve instead of replacing it.

SERVICE PROCEDURE

Remove the EGR valve following Workshop Manual (WSM), Section 303-08.
Remove the EGR valve O-rings and gasket.
NOTE: THE EGR VALVE MUST BE HELD VERTICAL WITH ACTUATOR ASSEMBLY ON TOP FOR THE COMPLETE PROCEDURE. DO NOT ALLOW CLEANER TO ENTER THE WEEP HOLES IN THE BOTTOM OF THE ACTUATOR. (FIGURE 1)





Figure 1 - Article 06-19-6



Soak the EGR valve with carburetor cleaner or injector cleaner to loosen deposits. Do not use brake cleaner, this can damage the actuator seal. (Figure 1)
To clean the seats of the valve, hold the pintle shaft at the upper pintle head crimp (Figure 1) and gently push it open against the spring. Once open, insert a soft object to hold the valve open.
NOTE: IF SOAKING (SUBMERGING) THE VALVE MAKE SURE THE FLUID DOES NOT ENTER THE WEEP HOLES OR ACTUATOR SEAL. FLUID IN THESE AREAS WILL CAUSE THE VALVE TO MALFUNCTION. (FIGURE 2)





Figure 2 - Article 06-19-6



Use a non abrasive pick or brush to break up deposits.
Use carburetor cleaner or injector cleaner to spray away remaining deposits.
Dry the EGR valve with compressed air.
Wipe the EGR valve clean using a clean shop towel.
With new O-rings and gasket install the EGR valve following WSM, Section 303-08.
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 datalogger to take active command of EGR valve. Ensure valve passes EGR position test in Section 4 of the PC/ED.
NOTE: IF THE EGR VALVE PASSES THE POSITION TEST IN THE PC/ED THE VALVE SHOULD NOT BE REPLACED.



If the EGR valve does not pass the position test, replace the EGR valve.
The root cause of the coking 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).
