Another Super Duty Glitch
Some 2011-2012 Ford F-Super Duty vehicles equipped with a 6.7L diesel engine built on or before 2-12-12 may exhibit a run-rough and/or misfire concern with or without DTCs P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 and P0308.
1. Inspect all eight fuel injector hold-down clamps for a broken ear.
2. If any broken ears are found, replace the clamps(s), re-seal the affected injector(s) and replace the injector-to-valve cover seal.
3. Pry the injector-to-valve cover seal out of the valve cover using a screw driver. The new seal can be installed using a 22 mm socket (rolling/pressing the seal in place).
4. Inspect the fuel injector return hose connection at the injector(s) for damage and replace if needed at this time.

Leaky Internal DEF


Some 2011 Ford F-Super Duty trucks equipped with the 6.7L diesel engine and built on or before 8-3-2011 may exhibit a MIL on with DTCs P20E8 and P202D. These codes are set by a small diesel exhaust fluid (DEF) leak internal; to the reductant pump assembly.
1. Using a scan tool, check all continuous memory DTCs. Are DTCs P20E8 and P202D both present with no other DEF-related codes?
a. No…do not continue with this bulletin. Refer to powertrain control/emissions diagnosis in the manual for normal diagnostics.
b. Yes…replace the reductant pump assembly. Refer to workshop manual section 303-08. When replacing the reductant pump assembly, the reductant tank must be removed. Tilting the tank down to gain access may allow dirt/debris to enter the pump supply port, causing a repeat reductant pump failure. The replacement reductant pump assembly is available as P/N BC3Z-5L227-D.
