P2004, P2006; Intake Manifold Runner Control (IMRC) Function and Diagnostics (CDT)

Intake Manifold Runner Control (IMRC) systems can be challenge to diagnose, especially when the service information available to you isn't accurate! In this training class we will explore how an IMRC system functions and how to approach diagnosing it properly the first time. Join us for the fun when we look at a 2004 Ford Focus with a sluggish driveability complaint and setting codes P2004 (IMRC stuck closed), and P2006 (IMRC stuck open).

[@Keiserm5]

I dont understand how yoy guys arent at the top when you google search p2006. Literaly found what i needed to know in 5 mins of scdollung through the video. Thank you!

[@sewardfriend1094]

This is so helpful. The breakdown of how the intake manifold works was exactly what I needed to know! Especially going over how the codes are actually meant for the swirl control system, that cleared up several headaches I’ve been facing while trying to diagnose this issue. Now I definitely want to get the manifold off and check out those flaps considering my engine has an oil leak and there’s a ton of that “gunk” you were mentioning around the intake and engine bay. I wouldn’t be surprised if the actuator or the flaps got stuck because of that.

[@W.Khairi]

Thanks to u guys, I finally understood this runner/swirl systems, Cause I had a 2011 sorento with these two systems and really threw me in a loop. Thank u very much guys, your broadcasts are as informative and as entertaing as always, Love it.

Stoney guys like you is always what it was all about! Thank you for the kind words, I will miss you guys. Mark Hicks

[@jon4915]

Great info. Especially concerning the confusion between how they named IMTV, IMRC etc. Made a new harness for an 05 Focus ZX4 ST, think I may have mixed up the wiring for the two solenoids lol. Gotta buy the OEM powertrain control / emissions diagnostics manual… workshop manual and wiring diagrams manual won’t cut it for this mess lol

Luv yur lessons. Thank you and God bless you gentlemen

[@marktorr5380]

I learnt a lot... cheers guys "keep them coming"

[@GoTechTraining]

Hey Mark, thanks!!! Glad we could help! Mike Becker, Technical Services Instructor

[@MrMacanna]

Just ordered the PCV valve and tube after I ordered a new manifold. When I removed the old manifold it had all the gunk in it. Car is 2004 2.3 Ford Focus zts. Rather than pay the $300 for the AH manifold I purchased an AM for $60 and plan to add one vacuum port on the top.

[@trail457]

I was looking for this info,Thank you for your great job.

[@jenniferjerome8544]

Congrats on the retirement!! I highly recommend it.

[@josephclay1341]

Hi Mike and Mark thanks I have a problem with a 08 f150 3 valve stuck open I'm going to pull the intake with a bit more info thanks for the help xl

Hey Joseph, thanks for watching! Mike Becker, Senior Instructor

[@donnasmith9285]

So I have a 2006 mazda3 2.3 and it was coading P2004,and it was coming up intake manifold Runner control,so it's actually the swerle control system,, correct... please help me

[@fredroejr7474]

What is the little white lever that actuator is connected to????

[@FransceneJK98]

I had the IMRC replaced with a new one and the check engine light keeps coming back on. 😢

[@stingingpluto5892]

I had a p2008 code and another saying my MAF sensor my car is misfiring and its driving me crazy i dont know what to do

[@kelconinc]

Thank you for explaining this! I did the pressure test on my manifold. The solenoid is activating the lower shutters/valves but when I apply manual pressure, vacuum the lower valves are leaking very slowly. time for a new one? I have a constant 500-1000 RPM idle fluctuation . thank you again

[@GoTechTraining]

Hey Jude, thanks for watching! Are you getting any trouble codes? I'd hate for you to go replace the manifold only to have something else causing your idle fluctuation. Mike Becker, Senior Technical Instructor

[@kelconinc]

@@GoTechTraining that's been my problem, no codes at all. Total vacuum problem. I pull the vacuum line off the actuator solenoid, car idles fine just sluggish due to open vacuum. That's the only thing I can think of since everything else is hooked up to the computer and should throw a code. Plus I already replaced just about every airflow sensor, Mas air, MAP, Knock and was probably going to do the EGR if I take the manifold out again.

[@cartersgarage392]

Ever seen a P2008 code? It's on a 2018 dodge 6.4 hemi. The code pops up even with the actuator totally removed from the manifold. Ideas?

[@jeffwatson151]

I had an intermittent lifter tick and first my IMRC was stuck open on bank one now it's stuck closed.

[@rebeccaholt9796]

DIY-er here - What is a runner? That definition would help with the concept of the system and what it's doing.

[@GoTechTraining]

Hey Rebecca, A runner is a flap or door in the intake manifold the moves during different loads and engine speeds. The movement changes the velocity and direction the air enters the cylinders which can help with performance and complete combustion. Hope this helps, thanks for reaching out Ryan

[@jgeorges3061]

MARK, wish you all the best in your retirement good luck and god bless my friend cheeeeeers.

[@GoTechTraining]

Thank you J Georges, I wish you the very best, God bless you and yours! Mark Hicks

[@bestofthebest3821]

08:31 the long runners are there for low rpm/idle when engine vacuum its strong and pulls the air through the long runners.. at higher rpms vacuun drops so it needs a shorter runners

[@jenniferjerome8544]

I have a 2004 Mercury Monterey experiencing the P2006 code. Does this explanation on that Ford be the same for my Mercury??

[@GoTechTraining]

Hey Jennifer, yes the P2006 will be the same for the Mercury. Mike Becker, Senior Instructor

[@highlife6951]

Hey there, if I remove the runner control valve, should it move when the key is turned on?

[@GoTechTraining]

Hey High Life, remember this engine has runner and swirl control. If you remove the valve that controls one, the other will still move. Mike Becker, Senior Instructor

[@Thunderroad8517]

What is p2015 hard fault?

[@cloudyandoracle]

I have a jeep patriot and getting code p2006 intake manifold runner control stuck close bank 1. Any idea?

[@GoTechTraining]

Does the runner solenoid get power and ground? Could be just a manifold issue. Mike Becker, Senior Technical Instructor

[@RBGgamerr]

Am having the same problem with a lexus is 250 07 Code 2006, 2004. Any help?

[@GoTechTraining]

Hey Gavin69, the first step would be to monitor the signals to the valves and see if they are being commanded. From there you'll need to verify the flaps can physically move. Mike Becker, Senior Technical Instructor

[@heinricherlmt]

Hey. So the answer was that the thing was just dirty and needed to be cleaned? I might’ve missed the part where they said that directly. All I could tell is that their message is to “search for the answer beyond the computer diagnosis.”

[@GoTechTraining]

Hey Leslie, cleaning may have saved this one...maybe. Hard to say for sure. Either way being dirty and sticky for all that time wasn't good for the actuators. Mike Becker, Senior Technical Instructor

[@johnnylemoine2478]

Thank Yall I enjoyed it .

[@GoTechTraining]

Thanks Johnny!! Mike Becker, Senior Instructor

[@mariothanasi2017]

Hello sir. I have exactly same ford focus 2004 2.0 . Show me Code p2004 . Do i need to take off manifold or is a valve? I changed both solenoids. Still show p2004 ? Do i need to take it out and clean it ? Does is works or just buy a new one

[@andrewhigdon8346]

Twice on my wife’s 2008 4 cyl. Mercury Milan the obd scanner noted a vacuum leak. Easily found them and replaced bad vacuum lines, near front top of engine in intake area. The first one may have been there for many months as the car had belonged to my. Ice before hand, and car maintenance was unheard of. Could these vacuum leaks contributed to all the extra gunk in the intake plenum?

[@hdsmotorsltd470]

very nice and very helpful, my car is VW Touran 1.4 TSI 2009 automatic i have my car code 2006 with engine lights, sometimes comes up and sometimes goes away for a while and need to delete it please guide me

[@dalodrin1346]

I have a p2006 code on my 2015 audi a7 what could it be

[@GoTechTraining]

Hey Dalordrin, it's related to the intake manifold runner system. You may end up needing to pull the intake and inspect the flaps? Mike Becker, Senior Instructor

[@dalodrin1346]

@@GoTechTraining I am not yet accustomed to all the parts of this car would you know what side the flaps would be on and if a recent intake filter change would have caused anything

[@davisonpartlocator]

can the intake runner casue the vehicle to stall in revesre

[@davisonpartlocator]

the vehicle has a code p2004

[@GoTechTraining]

I suppose it's possible. If the flaps are falling and blocking the intake port, sure. It only happens in reverese though? It could be something else? Vacuum leak issue? Mike Becker, Senior Technical Instructor

[@Baba_Yaga888]

awesome video learned a lot

[@GoTechTraining]

Thanks Michael L! Check out our recent stuff if you want to learn even more :) Mike Becker, Technical Services Instructor

[@jameybarisoff]

So what is the remedy? Clean the intake runners if not broken? Or you gotta replace it?

[@mighandball13]

Yes

[@k2thayle]

Can this issue be solved by cleaning, or was the manifold replaced completely?

[@GoTechTraining]

Hey Kyle, that depends on the condition of the runner assembly. If they aren't broken or loose, maybe a cleaning will take care of it. Mike Becker, Senior Instructor

[@pandikristo5005]

You right before replace need to clean the mechanics don't like to do this. I clean tomorrow and let me see.

[@karinestg100]

Anyone knows how long it takes to replace the intake manifold? I have a 2006 focus. My actuator is electronically controlled. I guess till 2004 they were vacuum operated

[@sh3llshockr167]

about 2 or 3 hours if your carefully following along with a video.. After your first time you should be able to do it all in under an hour. Fords are very simple and straight to the point engines I love em!!

[@karinestg100]

Thanx. Replaced my manifold a few weeks ago. All is good now. Went well apart an intake bolt that wouldnt come out. Finally got it. Took me 2h 👍

[@jgeorges3061]

the answer is C. now i need one of those shirt and thankyou.

[@GoTechTraining]

Hey J Georges! I'll make sure to get one sent out to you right away. I think I have an email from you. Thank you! :) Mike Becker, Technical Services Instructor

[@abdolhakwik9125]

Answer C forsure!!! constantly allowing a/f ratio into conbustion chamber giving more power and responsiveness but lacks fuel economy cause its wasting extra fuel!! engine studders because not all are stuck open so its uneven pressures inside! thats what i think! not sure if im correct but thats what makesense!! My sister has both codes on her 09 Mazda 3! yeah they expensive!

[@GoTechTraining]

Yeh, you are correct! It was C. They do get expensive to fix. If you ask me it's kind of a cheap design. Plastic that is constantly moving right next to a hot cylinder head is always going to wear and run into issues. Thanks for commenting. Mike Becker, Technical Services Instructor

[@kphillips7922]

Seems like the power valve is faulty and the accelerator pump is worn.

[@GoTechTraining]

Seems like a foreign language to me :) carbs are definitely not my forte! Mike Becker, Senior Technical Instructor

[@andrewhigdon8346]

Carbs man. Oh, the memories.

[@lgonzalez1154]

Could it cause the vehicle to stall when snapping the throttle?

[@GoTechTraining]

Hey Stand Alone, sure it might. Depends on what is exactly wrong with the flaps. If they are not moving, but in good shape it probably will just make the car lack power...but if they are broken, they could move and block the air entering...which could cause a stall condition. Mike Becker, Senior Technical Instructor

[@lgonzalez1154]

Wells Vehicle Electronics I've checked just about everything I'm having a tough time with it....the only stored code is high input on the fuel tank pressure sensor no other codes

[@GoTechTraining]

Yeh, I don't see how a fuel tank pressure sensor could cause that. What kinda car you working on? How are the fuel trims? Mike Becker, Senior Technical Instructor

[@lgonzalez1154]

Wells Vehicle Electronics 05 Cadillac cts 3.6 fuel trim at idle hover around -2.5 to 0

[@GoTechTraining]

That seems pretty normal. Any codes besides the one I assume is in there for the FTPS? Mike Becker, Senior Technical Instructor

[@andrewhigdon8346]

Homogenous mixture is the term they are looking for.

[@toniencheff4046]

Thank you!!!! C

[@MADTYGER66]

Their both correct

[@jerziballer24]

I diagnosed 1 on a ford it was stuck open. they are expensive.

[@GoTechTraining]

Yep, they can stick open or closed or both in this case. Thanks for watching Jason and for the comment. Need anything be sure to let us know. Mark Hicks Wells Vehicle Electronics

[@andrewhigdon8346]

Can’t it just be cleaned? Assuming the plastic bits aren’t broken?

[@brad2548]

[@mike197714]

I know my comment comes 5 years late: Hey that happened to me. I just fixed my 2007 Ford Focus 2.0L thermostat. It was $300 plus. After I got the bill. They cleared the code. Then what happened it came back with a another code. It said: Intake manifold control valve is stuck open. This was yesterday. I said We just paid to fix the thermostat. Now the intake manifold isn’t functioning. It’s really weird. I collect Social Security Income. My mom is stretched thin. I’m kinda stressed. I’m a person with emotional and behavioral disabilities that are sever. My poor mom. Is worried bout my aunt and uncle. She’s not doing so well money wise. I used to look to her on money.
