Not in all cases, sometimes the clip comes off, reinstall the clip and you should be fine unless build up on the shutter valves are keeping them from openning, dearler cost is close to $300 to repair

You will have to replaced the imrc or the problem will not go away. your local dealer probably stocks the part and can install it for you in about an hour.

2004 ford f 150 5.4 3V pulled intake fixed vac hose came off replaced imrc & still show intake runner control closed bank 1 Still has no power when I get in it to pass something any ideas?


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.

How to fix the problem?


check that the engine vacuum is operating as this is what opens/closes the IMRC valve(s) , all hoses are connected correctly let me know how you get on

Code p1518



Trouble Code: P1518

Intake Manifold Runner Control Shutter Valve (Stuck Open)
Possible Causes:


IMRC control circuit shorted to ground or to system power (B+) . IMRC shutter valve actuator is stuck closed . IMRC vacuum hose is loose or disconnected. PCM has failed .From the Mazda Repair guides.

P1512 How to fix it?


The code involves IMRC runner valves in the intake manifold. I would do some internet research for the code and see if the repairs are within your abilities.

Mil comes on with p2004/ check valve stuck open. Where is the check valve located


P2004 - Intake manifold runner control (IMRC) stuck open (bank 1)
Description - This DTC is set when the IMRC is commanded closed, but the IMRC monitor indicated open. This DTC replaces P1518 and P1537.

Probable causes - IMRC monitor signal circuit shorted to PWR GND or SIG RTN
- Damaged IMRC actuator or solenoid
- Blocked vacuum hoses

Diagnostic aids - Monitor the IMRC and IMRCM PIDs. The IMRCM state should change when the IMRC is commanded open or closed.

This control valve generally is located on the back of the intake.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

P1512 of my 00 MPV, what is the solution?


DTC P1512 - VARIABLE TUMBLE CONTROL SYSTEM (VTCS), STUCK CLOSED
The air intake hose that goes from the air filter/mass airflow sensor to the throttle body they are common to crack. This air leak can cause a lean condition if that checks out ok then the issue is usually a faulty mass air flow sensor .This would need to be checked next.

Usually the actuator valve is stuck closed. These are the most common causes of the P1512 and possible causes are:
* ECT sensor malfunction.
* MAF sensor malfunction.
* IAT sensor malfunction.
* EGR boost sensor malfunction
* TP sensor malfunction.
* CKP sensor malfunction
* VTCS solenoid valve malfunction.
* VTCS shutter valve stuck closed.
* VTCS shutter valve actuator stuck closed.
* Short circuit between PCM and VCTS solenoid valve.
* PCM malfunction.

I would start with the mass air flow sensor this can cause all these issues. Then the cat. This would be the next step.

I hope this helped (remember to rate and comment this answer).

Obd 2 code reads p 15 18. There is no code number to relate to the problem. Do you have the answer? [ check engine light on 1999 ford taurus]


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!
