How to service the intake air duct on 2004 Ford F-150 Heritage?

The first step to service the intake air duct requires removal of the accelerator control splash shield along with its bolts before preparing the shield's removal. The service process starts with removing the electrical connector of the intake air temperature (IAT) sensor followed by the positive crankcase ventilation (PCV) hose and the idle air control valve (IAC) inlet tube. Standfast the clamps while trimming off the air cleaner outlet tube and resonator. When installing the device verify that the outlet air tube seals tightly to stop unmeasured air from entering the engine. Before reinstalling the air cleaner system users must verify that both inlet and outlet alignment tabs fit together properly through the slots between the units.
