Thank you so much for this

[@user-bu2cp3rn1y]

If you have a good scanner , it has an option called throttle relearn , it will relearn the idle

[@projectskadi9354]

I do and it didn't do anything I think coolant got into the connector cuz I had to take the throttle body out and coolant dripped into the valve connector and the wire harness and since then the code came on

[@AngelRuiz-hb9cv]

Wow, I love this video. It was straight to the point. Thanks

Thank you

Thanks bud for info and help....

Are those things possible causes for a car having cranking issues? Auto Zone gave me a paper with this code. My car has problems starting.

May I ask 2014 accord lx Where is located idle air control valve?

[@Elvys809]

I had the same thing and did the relearn idle and checked for leaks and nothing i did almost everything that says on the internet the last thing that i did. I went to the mechanic and with a computer he reset the throttle body and relearn the idle and then it got FIXED. Everything went back to normal

[@justingilmore7366]

How much did the reset and relearn cost ?

[@Gone_Rogue300]

How does someone do the relearn ?

[@Elvys809]

@@Gone_Rogue300 they do it by the computer 🖥️ with a OBD2 cable plugged into your car 🚗 they have to reset it and then do the relearn idle

[@Elvys809]

@@justingilmore7366 he charged me about $80 dollars he is my friend he didn’t charged me a lot like other mechanics

[@Gone_Rogue300]

@@Elvys809 all I did was take the battery post off and starter removing the exhaust manifold and removed the EGR hose and coolant hose to attempt to get tkt the starter from the top for an 08 Honda Fit! Then the idle started going nuts! When I put everything together.... Could this be just because I took the battery post off? Cuz I found a video on KZbin in regards to programming the relearning system and it worked for me.

Where is the iacv located of 07 odyssey?

[@sonora6702]

Is this an emergency or can i drive it for a few days?

[@keithnourse6829]

Do you know where the ideal air controle velv is on a 2010 Honda Civic with a 1.8l engine?

[@whyingo7964]

Some Hondas don't have an idle air control (IAC) but electronic throttle control (ETC). If yours has one, it will be located at the bottom of the throttle body.

[@keithnourse6829]

It has no throttle cable so I'm assuming that it is electronic throttle control

[@Snoop_was_here]

That code appeared after having the valve cover and gasket replaced. I don’t understand

[@WinstonGoesLive]

Same here Did you fix it?

[@Lucas-jy7cv]

Did it get fixed

[@icasualyt8875]

You likely didn’t put it on right used the existing original gasket which has worn down, if the code came up afterwards

[@sayingitlikeitis]

there's no idle air control valve for 2007 honda accord and i'm going crazy here

[@projectskadi9354]

Pretty sure it's built into the electronic throttle body from 03-05 it was a cable driven throttle body in 06 and 07 it was switched to drive by wire

[@dariomendoza1518]

Mines the weirdest High Idle it starts at normal and it goes all the way to 4.000 to 5.000 rpms or higher if I let it!!I replaced the idle sensor throttle and disconnect every known thing known to mankind and stiil Takes off on its Own!!! to 4.000 5.000 rpms!!

[@projectskadi9354]

Make sure you reset the computer after anything that alters that af ratio if you replave the iacv it needs a ecu/pcm reset and/or an idle relearn procedure same goes for a throttle potion sensor. If you replaced the tps you need to make sure it's voltage is set to the manufacturer spec if it says it needs to be at .50 volts it needs to be just that. You can most likely find a video or forum to learn how to do it
