ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
Coking deposits inside the turbocharger turbine housing can impede vane response causing high or low instances of exhaust pressure. Unexpected exhaust pressure results can cause over-boost, under-boost, insufficient or excessive exhaust gas recirculation, or unexpected EGR valve position, resulting in these symptoms.
For F-Super Duty, Excursion, E-Series vehicles built on or before 9/29/2003, follow PPT KA in the PC/ED manual diagnostics. If the PPT in the PC/ED manual diagnostics leads to turbocharger replacement, use the Turbocharger Inspection Procedure first to check for internal turbocharger oil leaks. Then, determine if the turbocharger can be repaired with a center housing rotating assembly (CHRA) replacement or if it can be cleaned instead of replacing the entire turbocharger following the turbocharger reconditioning service procedure.
For F-Super Duty, Excursion, and E-Series vehicles built on or after 9/30/2003, perform the Powertrain Air Management Turbo Boost test and VVT test with IDS. Use of the VPS tool 418-626 along with IDS/VMM is required. Tool 418-626 was shipped in kit TKIT-2007VP-F and TKIT-2007TV-F. Dealers should have received one or the other of these two kits.
Refer to the updated online WSM, Section 303-04D:
for diagnosis, testing and reconditioning of the turbocharger assembly.
For F-Super Duty 650-750 vehicles, refer to the updated online WSM, Section 303-04B: for diagnosis, testing and reconditioning of the turbocharger assembly.
