P2004 Check VSC on display. Code refers to "intake manifold runner control stuck bank 1" What do I try?

with the P2004 and P2008 code OBD-II Trouble Codes: Intake Manifold Runner Control Stuck Open Bank 1. The easiest fix is to replace the Intake Manifold Runner Control @ carparts.com for a total of $35 bucks. But first check the vacuum hose attached to the Runner Control. If its cracked or has some sort of leak it'll throw the codes.
Best to you.

P2006 = Intake manifold runner control stuck closed, Bank 1.
There is a set of 'choke' valves built into the intake manifold on the vehicle.
They are sticking closed, affecting the fuel to air mixture getting to the engine. The switches/solenoids may have failed so the will need to be tested or replaced.

code p 2004 refers to intake manifold air control actuator bank 1--actuator stuck open===causes --wiring--intake manifold air control actuator---mechanical fault
it also refers to intake manifold air control solenoid bank 1--solenoid stuck open=== causes --wiring---intake manifold air control solenoid---mechanical fault
reference auto data technical fault codes
I cannot find reference to the VREF or VPWR as they may be referenced in a ford workshop manual so you may have to ask a ford service person what they stand for but I suspect that they will come back to the same thing as listed in the causes

Intake Manifold runner control stuck open - bank one:
- Intake Manifold Runner Binding Or Sticking
- Faulty Manifold flow valve
- Manifold flow valve harness is open or shorted
- Manifold flow valve circuit poor electrical connection

There is a factory service bulletin for this problem for 2007-2008 Dodge Avengers. (JS)

It is attached to the intake manifold, it is a valve that adjusts the runner length of the intake for optimal performance and fuel economy.

code p2004 refers to intake manifold air control actuator bank 1---actuator stuck open===causes --wiring--intake manifold air control actuator --mechanical fault.
also refers to intake manifold air control solenoid bank 1 solenoid stuck open===causes--wiring intake manifold air control solenoid --- mechanical fault
you may be able to remove and clean the units to ensure they move freely otherwise replace them

code p 2004 has two references
intake manifold air control actuator , bank 1 --actuator stuck open====causes ---wiring---intake manifold air control actuator ---mechanical fault
second reference is
intake manifold air control solenoid , bank 1 --solenoid stuck open===causes ---wiring--intake manifold air control solenoid ---mechanical fault
probably means the same as what you have but in a more easy to understand method

code p2004 refers to intake manifold air control actuator-bank 1--actuator stuck open===Causes---wiring--intake manifold air control actuator---mechanical fault .I would check blockage and wire connections Then I would replace the actuator But I would not tear down the engine as it is between the air filter and the manifold. Check the air cleaner element

P2004 Intake Manifold Runner Control Stuck Open (Bank 1) check for a cracked or broken vacuum hose on the intake manifold, be careful, the little nubs they attach to are normally plastic so use care when removing, the dealer will say new manifold, But check for hose fittings or a cracked hose first
