Thanks, I found the location. it's @ the top next to the fire wall.
I ran a 24" long hose with "loom" on it to (relive stress and heat).

no code is a Good thing!

I wish GM had a "cool" site like this!

Add me to the list of people this helped. Got rid of my P2004 code on my 2003 2.3L by cutting off the split end and reattaching to the nipple. Thanks!

i have attached a photo of the intake manifold runner control(located right before the back bottom bolt to the intake manifold). the vacume line that runs from the EGR to this is on the bottom side. the angle the hose has to bend at causes it to tear open throwing the code "P2004". in the picture i am holding it to were you are looking at the back and it is upside down. the hose on the top left you can notice is torn open. just whip out a knife and cut past the torn part and put it back on and you will have solved the problem.

I know its been about 2 years since the last post, but if anyone still looks at this, thank you for the diagrams and the video and the pictures. I know nothing about vehicles, but I fixed my check engine light for $4.37! And now I know what an intake manifold is and what it does. Thanks everyone!!!

Ok so I've replaced the control module for the intake manifold runner and the code still pops up... I'm extremely melt tired of this dang code and I've given up on it. What else could it be???

Did you replace the vacuum lines.

No but I've checked them extensively and they're in good shape

I'm at the same place you are, except I replaced both vac lines. Still have a CEL. When I pull the Vac line heading to the intake I can hear that there was a vacuum in the line, so I'm at a lose. I don't think the Intake Manifold Runner Control valve itself is bad. I'm thinking its something in the intake plume itself.

Does anybody know if there's an actuator or solenoid that controls the valve in the intake?

Yes, there is. At the very very back of the intake manifold, you can see an odd little bulb-looking thing with a three-pin wire harness connecting to it. Immediately behind that is a connection for the vacuum line.

If replacing the controller didn't fix it, then you're left with one of four possibilities:
a) The actuator behind the manifold is shot.
b) There is a short in the wire harness connecting the actuator or controller to the PCM.
c) The runner valves themselves are stuck.
d) Your PCM is screwing up.

The best starting point is to try moving the valves yourself. Move some of the wires out of the way and reach as far back behind that manifold as you can. Try to find the middle area of the very bottom where the manifold connects to the engine. You can feel the end of the plunger from the actuator and where it connects to the line for the valves. Try pulling it in to make sure it can. That actuator is spring-loaded, so there will be a fair amount of resistance. As soon as you let go, it should spring right back down. Again, some resistance. If it feels stuck or it's really hard to move, pull the manifold off and clean it thoroughly.

Checking the rest of it is a bit involved. I'm still trying to figure out the proper numbers themselves. With mine, it's not stuck open. It's just surging between open and closed when it's supposed to remain closed. Vacuum lines are fine and I'm not getting any codes. I just got a new actuator, but haven't been able to confirm it's the problem yet. I'll try to work out a procedure for checking all of it. Even with the workshop manual and PC/ED tests at my disposal, I haven't been able to pinpoint it yet. This is a gremlin type of issue.

The solenoid is connected to the runner control on the side of the manifold. The monitor is connected to the actuator behind it.

With KOEO, use a multimeter to check the voltage on the following pins:
- Swirl Control solenoid pin 1 (LB/OG wire). Should match battery voltage (12-ish V).
- Swirl Control monitor pin 3 (BN/WH wire). Should be just over 5V.

These are the reference voltages from the PCM. If they aren't corrrect, you have an electrical short somewhere. Replacing either component will get you nowhere. If they are fine, then check Swirl Control monitor pin 2 (GY/RD wire) for ground against pin 3.

If all of that checks out, poke a paperclip through the back of Swirl Control monitor pin 1 (WH wire). Make sure you have continuity between the actual pin and paperclip so you can measure it while it's plugged in. When you do, plug it back in and start the engine. The voltage should be very very low. Expect a number around .125V. Now, reach under the throttle body splash shield and open the throttle plate. Get the engine up to around 3,000 RPM and look at the voltage. It should be VREF from pin 3, a.k.a. 5V.

If either of those didn't check out, try disconnecting the plug while measuring the voltage. If it changes drastically, the actuator is likely the problem. That part can either be purchased from a Ford dealer (part number 1L5Z-9L492-AC), or with a new intake manifold. Most available manifolds will specify if they include it or not.

2002 w/2.3. cel on, code p1537. like new under hood. pulled out the IMRC. hiss of vacume from fwd hose/nipple when removed from manifold like in earlier post. the one pointing down is open to atmosphere/ leaks inside of IMRC. is this unit bad ? or is this normal until power is applied ? then it closes the loop ?. never seen open vacume like this and be good... The dealer wants $169+tax. non returnable.
Like Bikerbones said, the crooks/dealers say "never heard of that before" minimum 2 hours troubleshooting... thanks Roscorpian, that info is a great help ! does anyone know how to tell if this IMRC is good or bad ? is it in the manual ? already got a non-returnable $180 thermostat on the shelf. original had part in backwards from factory. Dealer said it was radiator, not covered under warranty... My girls truck, babied since new. Thanks C300

You need to attach the line that runs to the intake manifold runner actuator.
