P1000 Engine Code 29 IACV Connector

[cwalton]

Sometimes I get a check engine code of 2 long and 9 short blinks. Does anyone have an idea of what this means?

IACV circuit malfunction . Rough idling
29-1 . Loose or poor contact of the IACV connector 4-25 . IACV or its circuit malfunction

Consider joining our club as a lifetime member, we have a pdf of the service manual available. I believe the membership is discounted until year end.

Thanks for the advice Neohio, I think I just became a lifetime member.

Where is the pdf of the service manual located?

@cwalton I tagged you in the thread.

I am not very good at maneuvering around this forum, so if that helps, thanks. Thank you and Snuff for all your help. Next job will be digging into the buggy and figuring out the code issue.

I have found broken wires going to the IACV connector. I dont know what these connectors are called to begin finding new pins and crimp tool. Can anyone help?

 

[Neohio]

I had the a website saved that sold pins and pliers.
If you into my profile and find the thread i started about fuel injectors, i may have posted it there.
If not, i will check my pc at work tomorrow and see if i still have it saved.

 

[cwalton]

Did not see website info for pins on your thread about injector issues. Did i read it correctly when you said Honda may want to change harness for bad plugs?

 

[Neohio]

Correct, the proper repair according to my dealer is replace entire harness. My dealer was zero help on my issue due to diagnosing it myself.

Edit, hit up ebay and look at used harness pictures to see if you can find a cheaper harness to rob connectors from. Africa twin should have an iacv valve. Might be able to buy a small section and replace entire plug.

Edit 2.
Here is the connector in the club store

IACV connector for Honda SxS/UTV Honda Pioneer!

The IACV valve found on most all Fuel Injected Honda ATVs and SXS's has a habit of going bad. The issue for the Pioneer line is the wire will break inside the insulation causing a non-visible fault. Once you cut the head off the wire will fall apart. Our kit includes upgraded 18 AWG wiring...

Ok, thanks for the advice.

Pins should be universal across many lines from same manufacturer. Wouldn’t hurt to have 10-20 spare pins and seals for future use.

Hopefully you caught my 2nd edit above with this link

I believe they are called molex pins, should be able to get remove and install tools for the housing.

That is a cool site, think @cwalton needs the Yazaki 1.5 system. Go to By application/use and pick the connector.
We used to have a electronics store local that you could walk into and get anything. It was great.
