New IMRC Actuator Still Get Code P1518
 
Hey everyone, this is my first post. Great site, tons of info on here.

I've searched for this, but I can't find anything like what I'm experiencing. I had two codes for oxygen sensors and IMRC stuck open. I fixed the O2 sensors and tried to fix the IMRC box, but my light stayed on and the car runs like crap. So I ordered a new actuator from Tousley Ford, put it on, and it still doesn't work. The cable does not move, I even unplugged the connector while it was running to see if it would open, but it already was open. Is there a fuse for this or anything else I should look for? I'm running out of patience.

Hi AlfPrev, welcome to the site. I had the same codes on my car when I purchased it. I had the IMRC stuck open, I took the box out and opened it up and did a repair the I found on this site. Link- http://www.focusfanatics.com/forum/showthread.php?t=222180 If your not getting any power to it, take a voltmeter to the connector that goes to the IMRC box and test for power. As for a fuse, it should be fuse #10 on under your dash. Let me know if any of this helps.

Thanks for the reply. I did open two boxes and do the repair and it did not fix the problem. I just checked every fuse in the car and I did not find any bad ones. I had someone start the car for me while I looked at the cable and it does pull initially, but then let's go after a few seconds. Everything I've read says it should stay pulled until 6000 rpms. I read another thread that states it could be the idle valve, I have no idea what or where this is. I also checked the IMRC plug for power with a test light while it was running and two wires have power. I swear I read somewhere that someone had a problem with it working initially and the opening, but I can't find that thread now.

The idle valve im assuming your refering to the Idle Air Control Valve (IAC). The IAC basicly controls the cars idle, and when your rev your engine, it allows the engine to slowly rev down. Here is a link to a thread here on focus fanatics that shows you the location and how to clean your IAC. Keep me posted on your progress.

whats the specific IMRC fuse number and location spot?

EDIT: took me 2 seconds on google. Location #18? but they said under the hood not under the dash

I'm still trying to figure this problem out. I cleaned all the ground wires I could find except one that's so rusty the bolt is stuck( got pb blaster on it). I also cleaned the MAF and I removed the IAC and cleaned it, I also cleaned the throttle body which was gummed up. I took it for a ride and it does run better. Smoother idle and more low RPM power, but the IMRC is still not actuating and I still have a CEL.

As far as which fuse the IMRC is I don't think it's #18. I'm pretty sure that's the heated O2 sensor fuse.

crap well got that info from a thread here...

anyone know what number is it??? is it under dash or under hood???

Bump. I'm still having this problem. IMRC actuates upon start up, then deactivates a few seconds later. I have a CEL and getting code P1518 IMRC stuck open. I was able to remove the ground cable on the engine after heating the bolt, it was badly corroded. I cleaned it and reassembled, but the light is still on and I can see it is not working correctly. Someone has to have had this problem before, any more suggestions? Thanks

Are you sure the imrc is getting power?

AlfPrev 10-30-2012 08:01 PM

Yeah I checked with a multi meter. I'm getting 12 volts from two wires and about 2 volts from one, the other two are grounds. This is with the key to the run position and with the car running. Also tried another actuator and it does the same thing.
