[ BEST ] IMRC P1077 P1078 FIX 2002 Honda CR-V / RSX (🙏 donate if i helpped you link in description)

[@leonsamuel8558]

Still relevant to this very day, can't say how much I appreciate the time you took to share your knowledge about this problem. Thank you

[@DFRxSTANCE]

No prob bro i seen 1-2 videos on it and they weren’t that good so I decided to inform you all the best i could.

[@ndaddy273]

It was very helpful .I drive Crv in Russia. Most of the Russians drive Hondas assembled in Europe,so couldn't foud a good video review about that problem with russian blogers. You did a great job man!!!

[@graysonbagwell5344]

This is one of the best auto fix videos I've ever seen

[@PaulA-um9zw]

Where did you purchase the diaphragm from? Also, Could you have removed the IMRC by removing the power steering pump first then slide the IMRC out from the side of the intake manifold?

[@russdavis2087]

Excellent video and explaining the issue and the repair process . Definitely one of the best repair videos I have seen!

[@RickDavila]

very clear communication, easy to follow instructions, and a strong recap. I really appreciate that you took the time to make this, as I recently had this code trigger our check engine light on.

[@hammar324]

I had my intake manifold off less than a year ago to replace my starter!!! I'm so pissed off I didn't think to inspect the intake manifold / IMRC when I was doing that job. Now I have to take it off again!!! I can't believe it only took you 20 minutes. It took me all afternoon. Great video though! Thanks for posting.

[@mcilveenjd]

Really great video, I am a total rookie but not afraid to learn and try. so even showing the simplest things like loosening the bolts by the rad to wiggle the manifold out was very helpful- I didn’t figure that out the first time. Also when you say clean out , it might be helpful for newbs like me if you show what product to use and how to clean. Awesome and helpful

[@DFRxSTANCE]

mcilveenjd thanks I’m hoping you guys like the how to videos also if you guys would like to see me work on the car more please comment

Many thanks Delwin!! Your very instructive video made changing the "heater pipe" o-ring (Florida car), thermostat, and thermostat housing way easier and faster than going by the book. Verified IMRC was functioning & cleaned the IAC while they were accessible.

good video but where did you get a replacement diaphragm? i cant find them for sale anywhere.

Great Job. This will help me a lot. I specially like the fact that you show that you can take the manifold out without taking the latch bracket off.

Great video! Very helpful! But, where did you find the diaphragm? I have the same problem. I've already disassembled the IRMC valve and removed the torn diaphragm, but I can't find a new one. I don't want to spend $350 to replace the entire IRMC Rotary Valve.

[@DFRxSTANCE]

Thwy don’t sell it alone i got it from a junkyard

Hey. This video has been an incredible help. Do you have any tips on removing the lid at 6:50. I started on mine, quickly abandoned that idea thinking I’d break the plastic. Thanks man!

[@Para-ni5lx]

Wow THANKS for this detailed informative fix Sir. I replaced my starter today and P1077 appeared. This will be might next project.

[@degreco4199]

how do you replace the diaphragm? it looks like it's a non-serviceable unit. in other words you've got to anti-up for the whole imrc. i can't find a honda part anywhere.

[@JDMovation]

DeGreco I had the same issue with diaphragm being torn. I bought some krazy glue and a inner tube tire from bicycle. Cut a small patch and glued it on the outside and inside of the tear. Has been working great for about 8months now. I only spent $15.

[@DFRxSTANCE]

I used dawn dish soap 🧼

[@mattgoodman6161]

What did you use to clean the runner with? Brake cleaner?

[@DFRxSTANCE]

No never use brake cleaner i would use dish soap.

[@mattgoodman6161]

@@DFRxSTANCE I ended up using a non chlorinated brake cleaner which is safe for these molded plastic parts. I sprayed down the entire accessible inside of the intake manifold which was gunked up pretty bad and the IMRC as well and let them air dry before reassembling and installing back on the vehicle. Worked great and made the 600+ miles home without a hitch. Thanks for your response tho!

[@valgonzalez4673]

What are the steps to use the vacuum pump to install a new imrc

[@RandallFlaggNY]

Great Video! Where do you get a replacement diaphragm?

[@DFRxSTANCE]

Junk yard because they brand new you can not buy it separately it comes built onto the runner

[@cesarz188]

I replaced the IMRC on my 06 RSX but I forgot to apply vacuum before installing, is that the reason why my check engine light came back on and won’t accelerate when I punch the gas pedal? Or would this be a different issue with the connectors ?

[@DFRxSTANCE]

Yes you have to apply the vacuum

[@MrBuddhistzen]

Thanks so much for the video! Where did you find a new diaphragm to put in? Or did you replace the whole unit? New it’s $1000 from Honda for the whole unit

[@DFRxSTANCE]

Whole unit is about $350 from honda 1st time i took the diaphragm off one at the junk yard. Lasted about 1.5 years 2nd time i replaced the unit unit costed $350 local shops would charge $375 to install it. $725 plus tax was like $780 or so total.

[@littleghosdt]

@@DFRxSTANCE$350? 😮 from the dealership or hondapartsnow? Dealership told me $800 for the part

[@samuelgallardo8526]

How did you test the position sensor?

[@MapleMarmite]

Really great video on this! I had seen others that made it look like a much bigger job and I've been putting off doing it but this makes it look very achievable. Nice that you explained how it all works as well. Liked and subbed. If the CRV is your car, I'd like to see more vids on work you do on it. Question; If I go the same route and pick up a used diaphragm, how do you remove it from the body? There looks to be a finned circular piece of plastic holding it down - does that unscrew or pop out or what is the method? Thanks again!

[@DFRxSTANCE]

Hello were you able to fix it?

[@MapleMarmite]

Hi. I'm up to my butt in snow with no garage right now so it's a job I'm leaving until spring if all keeps going okay. I had a bad knock sensor as well which was affecting the running a bit but I managed to change that out and it seems to have helped.

[@bear_bois3147]

Great video. Very informative, very clear and went all through showing everything. One of the best videos I've seen

[@necrostheman04]

What does the hose that is connected to the intake pipe run to, you remove it at 1:49

[@DFRxSTANCE]

Dustin Langer i can check tomorrow morning normally a hose thats on the intake would be to vent the valve cover but ill check for sure. Are you talking about the hose thats comes off the the throttle body intake tube?

[@DFRxSTANCE]

Dustin Langer i see the one you mentioned ill check tomorrow.

[@mikewatanabe9273]

Great video I should have watched before I took it apart. I took all the bolts off and it popped off the internal arm. Is there any clocking sequence I need to know before I put it back together?

[@DFRxSTANCE]

Their is a vacuum clocking sequence

[@tracywalker5431]

What kind of Vaccum sequencing? Where can I find that? Really great video!

Hi, super cool video, very well explained! I have i question about my accord 2003 2.4l .When im driving with steady speed at around 80-90km/h sometimes the car slighlty shakes untill i let off the gas pedal and also the rpms are jumping up and down a bit for example at 90km/h the rpms jumping between 1900 and 2000 but i don't have check engine light popping. Do you think it can be caused by the IMRC or its some other sensor maybe?

[@DFRxSTANCE]

mitakks what shakes steering wheel, engine, brakes / tires

[@mitakks]

@@DFRxSTANCE feels like engine shakes and the gas pedal...like the engine doesn't have enough air or fuel something like that and rpms are jumping just a bit when the speed is steady

You can check to volt resistance when to the sensor that rotates the runner control module.

The separate diaphragm is not for sale, that's what the problem is. You need to buy whole thing and that stupid part is around $300. A bad design, Honda dropped it later on. Thank you for the video
