Want to buy IAC

Fix-A-Flat, Just put a whole can in the gas tank!

Works better in the oil tank...

Possibly the new intake manifold seals did not fully contact with engine surfaces after installation because of friction force and misalignments, so they was leaking. Seafoam lubricated the seals and they slided down under clamping force and engine vibration so now they perfectly match the surfaces should be sealed eliminating leaks, so no idle issues and engine check light anymore. AZmidget91 fixed the error 34 reinstalling the intake manifold seals. There is no magic.

Sounds like magic to me

You know that works better than seafoam! This new magic wand I just got. It fixes flat tires, blown headlights, blown fuses even locked up engines. I got it in Harry Potter land.

didn't know if you were aware of this cole....but jon dorenbos who is the long snapper for the Eagles is one hell of a magician in his spare time. completely irrelevant to this thread but i just like typing the word snapper.

Did someone say "snapper".
Still waiting for the NZ snapper to clear US Customs..

Wasn't Snapper a lawn mower from days of old ?

Alright, it happened again. Recently I applied CRC valve spray cleaner in the intake of my motorcycle and next day riding I started getting check engine light with code 34 IAC position too low. Check engine light appears after about half an hour of riding, probably when engine is hot enough. Check engine light can stay for a few minutes and then disappears for a few minutes and then appears again for some time and so on. There is no any idle issues or RPM issues or performance issues, everything works as always before. I cleaned recently the IAC sensor and whole throttle body assembly thoroughly while replacing rocker cover gaskets, I also replaced throttle body intake gaskets. But it has not fixed the issue, the check engine light still appears with this error after some time after starting the engine. Do you think CRC valve cleaner damaged the IAC sensor? Any another possible issues can cause this error code?

2009 Buell XB12Scg, breather reroute mod.

yep


Any another possible issues can cause this error code?

nope

 

[TPEHAK]

OK, I replaced IAC sensor with new IAC sensor and it has not fixed the issue. How do I fix it?

 

[AZmidget91]

Did you read the thread?

Either you mucked up the new intake seals when you installed them or you need to spend some time with all that fancy schmancy engineering equipment of yours to insure the mating surfaces between your intake manifold and heads aren't warped.

I'd revisit the intake seals.

 

[TPEHAK]

Is there IAC calibrating process or IAC plunger length adjustment should be performed prior to installation? I can not find this info in service manual.

The engine idles and performs perfectly, no issues at all, so I believe there is no intake seal issues. Is that possible that the IAC plunger tip can stick in the hole? Probably it needs some lubrication, especially after breather reroute.

 

[Silverrider]

Will any of these work ?

Those LOWE IAC will probably work because it looks like it has correct holes allocation.

 

[TPEHAK]

When I was cleaning throttle body I kept throttle baffle open holding it by the baffle itself. Is that possible that I bent the throttle baffle and now it has bigger gap at closed position and IAC valve has to move lover the shaft to compensate more leaking air through the baffle, and ECM senses it any throws the code 34?

I also reused IAC port gasket, is that possible this gasket is leaking?

The code appears only when engine is hot.

Can I see IAC position with Buell Bluetooth dongle and ECM droid? What is normal IAC position at idle speed 1050-1150 RPM and 4 degree on TPS?

 

[TPEHAK]

Measured coils resistance on the old IAC sensor, it shows 50 Ohm on both coils. Is it OK?

 

[TPEHAK]

Measured coils resistance on the new IAC, it shows 56 Ohm for both coils. So it looks like the old unit coils resistance is probably OK.

Also both new and old IACs moves the same way when I turn engine switch ON.

If I press "Active Intake Test" in the ECM Droid should it move the IAC plunger? I press it and nothing happens with both new and old IACs, they do not move.

It looks like the IAC on the Buell performs self-calibrating each time you turn ON the engine switch. Once you have turned engine switch ON IAC moves plunger down more than moves it up and it does not put big force on the plunger, so plunger touches the hole surface, then yield steps on stepper motor and then moves back to particular distance. So that is why you want to wait until check engine lite came OFF and start engine only after this, because of IAC performs calibrating process, you do not want to start engine instantly before it will have finished this process.
