Well a while back I took the intake off and cleaned it because I read that it could solve my issue. When we did this the runner seemed to move freely. I also ran seafoam spray through it after that because it still came back. Today I took the actuator off and tried to turn the runners with a screw driver, but it didn't move and I also turned the actuator and it springs back.

 

Well its not a physical aspect of the manifold I have taken it off, checked, cleaned it and it still comes back with the p2004 and p0420 codes. I have changed the actuator and throttle bottle numerous times and no luck. Does anyone know about electrical work on cars because I would like to see if I can track down the electrical problem.

I got stuck on step 13 on the guide on the first page of this thread. (K602) MFV Signal Circuit Shorted to the (F856) 5 volt supply circuit. When I tested the resistance between 6 and 5 I got nothing at all. So I went back to the top and tried the steps that I missed do to following the guide and I got to step 9. (K602) MFV Signal Circuit Shorted to ground and it showed no resistance to ground.

 

The runner shaft in the intake manifold turns smoothly opening and closing the vanes inside each runner? Or are they sticky? If the shaft and vanes are sticky you will continue to have this code (P2004) problem. Please recheck the operation of that assembly.

 

All - newbie, helping a friend with P2004 and P2017 on his 2008 Avenger 2.4. New solenoid didn't fix it. Stepping through the electrical procedure listed above but just realized I most likely performed an invalid test. Having found 5V in step 2, I am directed to step 7, checking for voltage at the MFV signal wire. Finding .50 while the connector is still disconnected at the control soleoid, I thought I had found an issue, but wouldn't that voltage only be present if the connector is plugged in? Yet the procedure doesn't say anything about that, which would require backprobing or poking a hole in the insulation. Can someone clarify? Thanks,

MT

 

While I can not speak for your electrical testing end of this situation, many folk have posted of this same code(s) troubles and have found it to be sticky runner vanes and seals of the shaft that is worked with the solenoid so many people have changed looking for the quick and easy fix. Being an 08 and probably high mileage, I would suspect and check for MECHANICAL problem before Electrical.
BUT that is just my OPINION.

 

I hear ya...thanks,

MT

 

Well just doing the electrical tests in the interest of thoroughness, as the car is my pastor's daily driver and doing the intake would require some careful planning. Want to be sure. Anyway, seems like all 5 circuits work, but the control circuit from PCM to the manifold flow valve (solenoid) has voltage with engine off. Is this right, or should it be only with engine running? Also, on the MFV signal from the solenoid to the PCM, with engine running, I get 1.1V, not 4.5-5V. I had no one to help me rev it, would have liked to see if it changed then. But anyway, I suspect getting any voltage there is probably proof that it works, but would appreciate any feedback, thanks,

MT

 

Hi all...Hey I had codes 2016 and 2017 on my 2008 Dodge Avenger SE 2.4L, I had a mechanic look and he replaced the Intake manifold runner control sensor...the code light still was on...I had to replace the whole intake manifold and that did the trick....I found on ebay, it was from TX . it was WAY CHEAPER than a dealer ...good luck

 

Yes sometimes that is the way to have to go, drop by the Newbie Check in Page and introduce yourself and ride to the whole forumz family!

 

Hello all, I'm new to forum and have a question. I have a 2008 dodge avenger 2.4L and am getting the code p2004. It seems that this means the IMRC is stuck open. Does that mean I have to replace the IMRC or is this something I can just regrease; or, could this be a wiring problem and if so, how would I go about checking that aspect?
Thanks ahead of time.

I hope this helps....i had 2016 and 2017 codes...same read...it said Intake manifold runner control valve...we replaced that and it didnt help, then replaced the whole intake manifold and that helped...just an FYI

 

Okay, I think I finally resolved the P2004 and P2017 on my pastor's 2008 Avenger. I swapped on an intake manifold from a 2009 Dodge Journey, P/N 04884495. The CEL is off and he passed Cal smog.

There's some great information/experience communicated in this thread. However, I think it's important to read the service bulletin related to this issue. The bulletin states that if you have a CEL on with DTC P2004, and no other symptoms, you may need a software flash update and an updated intake manifold. The bulletin covers some Avenger, Caliber, Sebring, Compass, and Patriot vehicles. For Avenger and Sebring, they recommend the flash update if your vehicle was produced through May 15, 2007, and the intake manifold upgrade if the vehicle was produced through March 22, 2007.

Also if you have an Avenger it helps to know a bit of history. I'm using Wikipedia for some of this. Apparently since the Avenger was re-introduced in 2008, Ma Mopar got a very early start on production and rollout; 2008 models hit the showroom floor as early as Feb 2007. As it happens, my pastor's car was manufactured in Feb 2007, so it seems apparent that he had the inferior intake. This particular vehicle also has 185K miles on it, so it actually lasted way beyond the normal expected service life. It may well be that most 2008 Avengers were in fact built early, and are subject to this issue.

Also, as far as I can see, the early manifold has metal flow flaps, whereas the new intakes clearly use some kind of plastic. Perhaps the plastic design does not accumulate the crud that the early one does; mine came off a wreck but was very clean and rotated smoothly without any binding. The $250 brand new units I see on eBay carry the correct updated P/N, and appear to have the plastic flaps.

I decided to focus on the intake and not the software update. My intake was $30, and $7 of that was the core charge. It has a sticker on the underside with the last four digits of the P/N, 4495. I didn't even mess with the injectors or fuel rail; I simply swapped the whole thing in. His throttle was also filthy so I cleaned that out as best I could, and the occasional hesitation he was feeling while driving is now gone. Not sure if it was the flow control or the throttle or both that was causing that, but it's now gone.

Based on magemorph's post, I disassembled the intake that came off the car, and of course it had the metal flaps and some crud. There may have been a very slight binding, but no side-to-side play. I removed the flap/shaft assembly and did see that on one of the plastic bearings, the inner diameter had separated from the rest of the bearing, so the bearing was wobbling on the shaft. So that's what will have to pass for 'differential diagnosis'! Thanks magemorph.

Anyway, check your engine bay for any dealer update stickers; maybe you already have the flash update and/or improved intake. Mine didn't. Thanks for all of the help; it was a life saver. BTW, I called my local Mopar dealer and they quoted only $340 for the intake.

 

Yup, this TSB is probably already here from the early beginnings of the forumz. As many of us here now were not here then, unless we read ALL original threads for ready recollection,maybe people coming on with such questions should search first and ask later.
Glad you got it straightened out for your "Pastor"!

 

Yeah, I'm an impatient type, usually don't dig too deep wanting my answers. It took me several months to unearth the TSB. Hey, forgot to attach that TSB. So maybe this'll help others like me...

 

I am sure that "fresher material" would always be welcome and helpful! Thanks!
