P2004 - IMRC Intake Manifold Runner Control problems
Posted 04 October 2010 - 08:17 PM
I did managed to clean the flap and the intake, but the error didn't go away. Checked all the hoses of the frequency solenoid valve (part nr 9 in the picture below), disconnected them all, cleaned all the electrical connections. Nothing. The error was still there.
The car was running just fined, so I didn't bother for a while. When I cleaned the error the light always came on when the car was at normal operating temperature.
I finally ended up buying a new frequency solenoid valve, but that didn't worked either. Either way I left the new valve in the car
Then, one day the light went off by itself.
Coincidence or not I had changed the fuel brand two days earlier.
Still didn't know what happened. There's now more than 5 months and the light never came back. http://typeaccord.co.uk/forum/public/style_emoticons/default/ph34r.gif
If possible clean the intake and see if the flap moves freely. Check the solenoid valve, clean it and check the vacuum hoses. I remember I even cleaned the EGR.

Just to clarify you un-plugged the sensor clip from the Frequency solenoid valve and the hesitation went away. How was the car from a cold start.
Adam mentioned that there was an intermittent vac leak fault with the frequency solenoid valve and a vacuum leak I suspect will cause the problems suffered by a few people, especially with face-lifts described as jerking.
You had a friend with this problem and were looking at the EGR, have you tried disconnecting the sensor clip on your mates car yet ? This could be the very exciting news that many people have been waiting for !! Fingers crossed :lol:

I think i will email nick aka nesh cuz he was having the jerking problem maybe he has the same problem, anyway i have ordered a brand new valve from Honda for £116 inc vat. and will be picking it up tomorrow morning so i will keep this thread updated....

I will definitely have one fault show up as I bought a replacement MAF and it wasnt connected/i forgot to connect it when started it so this will obviously throw up a fault. However I have two MAF now, neither of which I believe are faulty.
Finally when you disconnect this device and the MIL comes on, will the car not just go into limp home mode??? Because when my car was in that mode (when MAF wasnt connected) it didnt show any symptoms of jerkiness, but then again it didnt have any power and I dont think the turbo spools as the car obviously goes into a safe mode with default settings.
Any thoughts comments appreciated.. Should I try or wait till HH????

If it still exhibits the problem, then you can ignore the fault code coz you know it's not that...
So I'm not sure i understand the problem actually?

Really easy to do, but I'm sure Waj is going to take care of the DIY on this.
I think a few rep points on this as it is sure to help many other members and save many Accords being part exchanged!!
Personally the problem was just showing itself and slowly getting worse and starting to drive me mad, I was going to get it put back to stock and diagnostics.
Question is whether you replace the filter as well as the solenoid ?
So it certainly is one possible candidate for the jerking issues, after replacing fuel filters first though ! It will be interesting how many people find this works for
Thanks to everyone involved

I've also just had confirmation from Waj that his problem is fixed by replacing the part. He will post pics up soon :)
Time to make this a sticky me thinks :ph34r:
