I’m working on a 2009 4 cylinder Dodge Journey again. My cheapie scanner gave me P2004 OBD-II Trouble Code: Intake Manifold Runner Control Stuck Open Bank 1. The part to supposedly fix it is the actuator, Chrysler P/N 04884549 AD. Simple installation, get the big intake hose out of the way, and it’s just three screws into the end of the plastic manifold, and an electrical connector. I tore into it this evening. The old actuator seems to have a spot where it hangs up momentarily as I turn its 1/16" X 1/4" blade with a pair of needle nosed pliers. It is spring loaded.
Now to my question. The slot in the manifold that the actuator’s blade goes into only turns a few degrees with the pliers. Maybe 10º, I don’t think that’s far enough to actuate, open or close, the runners. Are the butterflies in the manifold actually stuck in an open position? If so, what is the remedy? I can turn the slot harder, but I am afraid to do it until I find out how far it’s supposed to turn.
This same. or a very similar, 2.4 liter engine is used in a variety of Chrysler vehicles, including Jeep, Neon, Stratus, Avenger, PT Cruiser, and surely some I can’t think of.
