#1: ECU error P1518 inlet manifold runner control Author: Golfguy206, Location: PeterboroughPosted: Mon Oct 01, 2012 11:01 am ---- Ok start with the basics:
2002 Multiplexed 206 1.6 16v (tu5jp4) - corrected from my original post of s 15v (doh!)
Planet says this is the error I have but I'm lost.
What does it mean and how do I fix it?
I have read somewhere that it relates to the butterfly valve that controls the low engine speed - where the hell is that??
Anyone got a picture of the offending item and know how to resolve the problem?

Maybe it means that you've dropped a valve
#3: Re: ECU error P1518 inlet manifold runner control Author: Golfguy206, Location: PeterboroughPosted: Mon Oct 01, 2012 1:02 pm ---- doh! Ha ha! Ok, fair enough!
It is a 16v, but thank you for the spell check. ☺
#4: Re: ECU error P1518 inlet manifold runner control Author: Seabook, Posted: Mon Oct 01, 2012 1:17 pm ---- never heard of this before but could it build-into the throttle body?
#5: Re: ECU error P1518 inlet manifold runner control Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Oct 02, 2012 12:28 pm ---- Ill give it a week & see if anybody else actually knows the correct answer
#6: Re: ECU error P1518 inlet manifold runner control Author: Golfguy206, Location: PeterboroughPosted: Tue Oct 02, 2012 2:47 pm ---- Noooo MrBsi, please tell me now!!! It's eating my mind away as to what this is!!!!
#7: Re: ECU error P1518 inlet manifold runner control Author: V9977, Location: Athens, GreecePosted: Tue Oct 02, 2012 4:28 pm ---- Why is this moved to 'solved'?
+1 Warning to the mods from me, now at 2.
My bet is on throttle-pane stepper motor if it's electric TB.
#8: Re: ECU error P1518 inlet manifold runner control Author: MrBSI, Location: What's it to you? ? ?Posted: Wed Oct 03, 2012 1:54 pm ---- Still not solved I see
The phrase all the gear & no idea springs to mind, there's no point having diagnostic equipment if you dont know how to use it correctly or what your dealing with
#9: Re: ECU error P1518 inlet manifold runner control Author: V9977, Location: Athens, GreecePosted: Wed Oct 03, 2012 9:29 pm ---- I think he touched the butterfly with engine running (possibly cleaning it) and messed-up the stepper position
momentarily while it was holding lock at idling. This threw-up a code which caused the EML to come-on
until the batt was disconnected and idle position for the butterfly was re-learnt, but code is still stored.
It's a lemon-entry my dear Watson..

#11: Re: ECU error P1518 inlet manifold runner control Author: V9977, Location: Athens, GreecePosted: Thu Oct 04, 2012 5:25 am ---- Intake air-valve (IMRC) fault possibly stuck-open.
#12: Re: ECU error P1518 inlet manifold runner control Author: Abzynthe, Posted: Thu Oct 04, 2012 5:44 am ---- This is for a Ford, but may be helpful.
Code "P1518 IMRC stuck open" this is one of many codes could mean different things for different auto makers.
IMRC is the intake runner manifold control. They are the secondary butterflys in your intake manifold, sort of like the secondary butterflys on an old 4 barrel carburetor. It should only open at high throttle, 3000 rpm or so. They are showing stuck OPEN all the time.
This code is associated with throttle control in Ford Windstars. One or more of the following actions will need to be performed to fix this situation.
1. The (IMRC) is part of the the intake manifold and will either need to be cleaned or replaced. Excess Carbon is a primary factor in this sensors failure.
2. There may be other contributing factors to causing this sensor to fail. In some models the sensor is attached to vacuum lines. If these lines are leaking (broken or brittle) these lines will leak and cause the sensor to stick open resulting in a (P1518) code. Replacing the vacuum lines, cleaning or replacing the sensor is required to clear this code.
3. On other models there are bushing clips that hold butterfly linkage in place. These bushings can be obtained at parts stores such as OReilys Auto Parts. The O'Reilly part number is 47099. The package says Vacuum Retainers/Bushings.
The vehicle will have to be driven after this repair is made to clear the code from the vehicles computer. This is typically anywhere from 60 to 120 miles.To jump start the reset you can unhook the battery from the vehicle for about 30-45 minutes. If the code does not return immediately (within 10 -15 miles) you are on the right track.
If an inspection is pending the removal of the code from your cars computer, you may have to travel 60-120 miles before this code will permanently clear.

At last, a clue
#15: Re: ECU error P1518 inlet manifold runner control Author: Seabook, Posted: Thu Oct 04, 2012 9:57 am ---- sounds like a proper code read is needed?

Wow, genius!
Best idea yet!!
Pp2000 is a proper reader (#facepalm)
#18: Re: ECU error P1518 inlet manifold runner control Author: Seabook, Posted: Thu Oct 04, 2012 10:26 am ---- if you use PP2000 you should be able to tell what's wrong with it, just follow the step by step trouble shooting
#19: Re: ECU error P1518 inlet manifold runner control Author: MrBSI, Location: What's it to you? ? ?Posted: Thu Oct 04, 2012 10:29 am ---- Any EOBD code reader is easily good enough for this fault
We already have the fault code, there's another clue stuck under the bonnet in the engine compartment, you just have to find it

Thats what I would have expected, however it just said "no further information" or words to that effect - no help really !
#21: Re: ECU error P1518 inlet manifold runner control Author: MrBSI, Location: What's it to you? ? ?Posted: Fri Oct 05, 2012 11:55 am ---- Post a picture up of the complete engine compartment & ill give you a clue where you need to look for the answer.
#22: Re: ECU error P1518 inlet manifold runner control Author: Golfguy206, Location: PeterboroughPosted: Fri Oct 12, 2012 9:31 am ---- Just before I go do that, allow me to explain what I understand so far.
I have read somewhere that it has something to do with an idle speed air inlet valve or something (not sure if this is accurate concearning the 206)
All i need is someone to let me know where tollok for the "defective" part or how to fix it.
Any one else help with this??
#23: Re: ECU error P1518 inlet manifold runner control Author: macca1411, Location: Westhoughton, LancashirePosted: Fri Oct 12, 2012 10:26 am ---- I thought this would have been solved by now.
I'd offer MrBSI a gift via paypal for his advice and just get the problem sorted. I'm sure it will be cheaper than throwing everything at it or taking it to a garage.
#24: Re: ECU error P1518 inlet manifold runner control Author: chuckstar34, Location: London/Worcester/ GrimsbyPosted: Fri Oct 12, 2012 10:26 am ---- Can I ask what problem you have to need a ecu read?? It sound like the throttle ensor not play the game.

So you didnt bother to read my post above?
Im out, good luck solving this one as it looks like no sod on here actually knows the correct answer

Not everyone but someone
This engine uses a split intake runner for each cylinder. It has a long skinny runner for low RPM use and a short fat passage for high RPM use. The IMRC is a system to control the secondary "butterflies" in the intake manifold.
When the engine is started the Powertrain Control Module (PCM) sends a command to the IMRC actuator to close the "butterflies". Above 3500 RPMs, the PCM takes the command away and the butterflies open, using spring pressure. The actuator has a position sensor inside that tells the PCM if the IRCM actuator reacted correctly. The P1518 code means that when the PCM commanded the butterflies closed, it didn't see them move.
While watching the IMRC Linkage, start the engine and watch for movement. If there is no movement, remove the upper intake to gain access to the lower intake. Check the IMRC shafts for carbon or other reasons for the system to stick. Grab the shafts and try to move them manually.

Have you solved that issue? I have the same problem and I can't find any fix for it.
