Ford focus intake manifold sensor

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.

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

Your engine has IMRC (intake manifold runner controls) that are supposed to stay closed under 3000 rpms. Over time they get carboned up and can hang open causing poor performance. Try to manually close the valve, if it immediately opens again the diaphragm might be bad. It would require replacing that IMRC.

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

code p1518= intake manifold runner control (IMRC) malfunction (stuck open)

the intake manifold has two runners per cylinder, feeding each of the cylinder heads
the IMRC assemblies are located between the intake manifold and two air passages for each cylinder.
one air passage is always open and the other passage switches from means of a valve plate.
below 3000 rpm, this valve plate is closed to improve low speed performance.
above 3000 rpm, this valve plate opens to improve high-speed exceleration.
the valve plates are opened and closed by the IMRC deactivation by the powertrain control module
(pcm) if your car or truck is not affected by the error code, the pcm may need to be reprogrammed
so that the error does not come up again. or you can connect an obd2 scanner and reset ever y time
it comes up. good luck!

Check for Intake Manifold leaks with either a water mist from a spray bottle or Choke cleaner. Do this while the engine is running and you will know about a leak with an RPM change. I read about some intakes were 2 piece and the intermediate gasket leaks.

Also you could clean the MAF on the air intake with Electric cleaner. If you have an old fashion Vacuum gauge you could plug in and see how steady Valves are closing by watching the Vacuum bounce from misfires.

Would like to know results on this case.

Check for a vacuum leak around the intake manifold area.It could also be something to do with any of the sensors mounted on the intake manifold,although they should set a trouble code.Manifold air pressure sensor,throttle position sensor,mass air flow sensor,idle air control sensor,etc.Take some brake cleaner or WD 40 and while engine is idling,spray around the intake manifold.If the engine speed goes up or down in relation to your spraying,that's the area of the vacuum leak.Good luck.
