Have taken the throttle body apart 100 times can't actually find what the intake solenoid is.

Anyone know what it actually is?

I know there's a eliminator kit for this code but what's the point buying it If I don't no where it goes.

Bike was in a crash last year and everything has been replaced including new handle bars and switch houses and wires.

Any help would be appreciated as am at my wit's end googling this and getting no were.

It has a karaken supercharger with the hose going to adapter under the MAP sensor.
Bike was running flawlessly up to the point of the crash.
Now that the code is there the bike runs like crap and won't idle it's the only error coming up on it.

Thanks

 

You live in Limerick, Ireland....???

If so, you have an HDI (Harley-Davidson International) model?

I believe the HDI models have an air control valve in their air cleaners.... Not on the manifold.... I believe it controls a flap in the air cleaner backplate..

I have no personal experience with that solenoid, or how it affects the tune... but...

Did you just put on the new air filter? Does that air filter use the OEM backplate?

I can understand how a broken air control valve, that is not opening properly in the air cleaner backplate, would cause your issues, but not sure how just removing it would cause your poor running issues... Unless.... the tune is set up for when that air flap opens/closes, and any time you remove it... you must retune the bike...

I believe the eliminator kit you speak of, just puts a load (1k ohm resistor I think) on the harness side connector to the air control valve which plugs into the air cleaner back plate. When the air control valve is removed, like when you switch to a high flow air cleaner, you will get the code and check engine light but it is missing, and the ECM can't see it... ... This false load tricks the ECM into believing the air control valve is still there...

Again... I don't see how removing the air control valve will make the engine run poorly... So if you just add the kit, eliminating the code, I don't think your engine will run better...

IMHO..... Either your air control valve is still present and not working (which could cause those issues), you just changed the air cleaner and without the air control valve the ECM NEEDS to be retuned (with no experience with that valve, I don't know if this is true), or you have another issue causing the bike to run poorly...

There is also an Idle Air Control module on the intake, but I don't believe that has anything to do with a P0661 code..

Hope that helps..

PS- here is a pic of the HDI backplate. That eliminator you speak of, will plug into the harness side of the connector #2 in this pic..

 

Thanks for your reply

The stock backplate is gone there is a hypercharger there instead.

It's the only code coming up what I was thinking why it was running so poorly.
I'll have to have a look over everything again to see is there any loose connections.
And yes it's an international model.

Any reason why it won't idle it backfires like mad when it gets a nice rev and coming off a high rev it starts spultering and just dies
as I said only code coming up is P0661.

 

Numerous things can cause that.. From a cracked fuel pump housing, to an intake leak, to bad plugs/wires, bad/dirty sensor, etc, etc...

Have you done any recent work on the bike?

Any recent mods?

Was it running great and then all of a sudden this happened....?

All I could find on that code, P0661, was the air control valve, and that kit to plug into the international models to alleviate the code/engine light...

Time to do a systematic assessment of the bike.... fuel, spark, and the compression...

Depending on the tools at your disposal, I would start with the easiest tests first...

I'd probably to a compression & leak down test just to rule out pistons and valves..

Then move on to the fuel system, checking fuel pressure, intake seal leaks, etc. Have you checked the plugs to see if you are lean or rich?

I would probably chase down electrical issues last, as they usually throw a code...

Many sensors like the IAC (Idle Air Control), IAT (Intake air temp), CPS (crank position sensor), VSS (vehicle Speed Sensor), and MAP (Manifold Air Pressure) may be in need cleaning before they throw a code...

Good luck with your diagnosis and let su know what you find out...

 

The bike was in a crash were the handlebars went through the tank.
Handlebars all switches and tank were replaced along with few cosmetic things such as rear fender and pegs etc.
I have all the tools at my disposal I'll go through everything again see what I can find.

Thanks for your reply.

 

In my experience, when the bike doesn't run right after I've done some work to it, the issue is usually something I changed, touched, or bumped during the work I did...

I'd expect your issue is with something that was handled during the repair...

I'd start with, and pay special attention to any electrical connectors that were changed, re-pinned, or handled during the repair.. Sometimes when you reconnect them, only one pin may bend and not make contact...

Also inspect harness wiring that could have been pinched, or stretched (which can cause a wire to separate inside the wire jacket/insulation....

Good luck with the repair...
