Some 2017-2019 F-Super Duty vehicles equipped with the 6.2L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P2004 and/or P2005. This may be due to a tear or crack on the intake manifold vacuum hoses resulting in a vacuum leak. Before performing normal diagnostics, inspect the intake manifold vacuum hoses. If a tear or crack is identified, intake manifold assembly replacement is not required. The vacuum hose assemblies are available as a lower level service part (base part 9E498).
