My 2004 ford focus check engine light is on and i was told the intake manifold control bank one is open what should i do

is anything I can do? Don't know , do you know how to test electrical circuit's using a DVOM - digital volt ohm meter ? Do you know what a wiring diagram is an how to read one ? P2008 - Intake Manifold Runner Control (IMRC) Circuit Open (Bank 1) Description: This DTC indicates a failure in the IMRC primary control circuit. This DTC replaces P1520. Possible Causes:

• IMRC control circuit open

Diagnostic Aids: Monitor the IMRC and IMRCM PIDs. The IMRCM state should change when the IMRC is commanded open or closed. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test HU .

P2008 code on 2005 ford focus

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

Is your check engine light on ? Any codes ?

There are three basic types of intake air sub-systems:

• Intake Manifold Runner Control (IMRC) electric actuated system
  


• Intake Manifold Swirl Control (IMSC) vacuum actuated system
  


• Intake Manifold Tuning Valve (IMTV)

These subsystems are used to provide increased intake airflow to improve torque, emissions and performance. The overall quantity of air metered to the engine is controlled by the throttle body.

Intake Manifold Runner Control (IMRC) Electric Actuated System
The Intake Manifold Runner Control (IMRC) Electric Actuated system (Figure 107) consists of a remote mounted motorized actuator with an attaching cable for each housing on each bank. Some applications will use one cable for both banks. The cable or linkage attaches to the housing butterfly plate levers. The 2.0L (2V) Focus IMRC uses a motorized actuator mounted directly to a single housing without the use of a cable. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder. One passage is always open and the other is opened and closed with a butterfly valve plate. The housing uses a return spring to hold the butterfly valve plates closed. The motorized actuator houses an internal switch or switches, depending on the application, to provide feedback to the PCM indicating cable and butterfly valve plate position.



Below approximately 3000 rpm, the motorized actuator will not be energized. This will allow the cable to fully extend and the butterfly valve plates to remain closed. Above approximately 3000 rpm, the motorized actuator will be energized. The attaching cable will pull the butterfly valve plates into the open position. Some vehicles will activate the IMRC near 1500 rpm.



WARNING: SUBSTANTIAL OPENING AND CLOSING TORQUE IS APPLIED BY THIS SYSTEM. TO PREVENT INJURY, BE CAREFUL TO KEEP FINGERS AWAY FROM LEVER MECHANISMS WHEN ACTUATED.

1. The PCM uses the TP sensor and CKP signals to determine activation of the IMRC system. There must be a positive change in voltage from the TP sensor along with the increase in rpm to open the valve plates.

1. The PCM uses the information from the input signals to control the IMRC motorized actuator based upon rpm and changes in throttle position.

1. The PCM energizes the actuator to pull the butterfly plates open with the cable(s) or linkage.

1. The IMRC housing contains butterfly plates to allow increased air flow.

Intake Manifold Runner Control Circuit/open bank 1

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
--2012

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

take the car to autozone and see if they can erase the codes for you..

Try some marvel mystery oil in your gas this should free the stuck valve

Check the PCV hose from the manifold to pipe. It will get soft and collapse, leak. It will turn light on. Check while running.

Its possible that you need check this TSB.

Hope helps.
