Throttle body cleaning and idle relearn 2007 Honda Civic 4D/5D 1.8 i-vtec R18A

[@jptrainor]

As an fyi for the comment readers: It is possible to do this with the throttle body left in the car, perhaps not optimal, but possible. Disassemble the intake as you see here to access the throttle body. Then depress the accelerator pedal to open the butterfly valve and reach in with a small brush to clean the throttle walls and valve. Be aware the you will have turn on the car (not start.. just on) to move the throttle valve to the open position. If the MAF sensor is unplugged when you do that then there will be two codes that you'll have to clear after you put everything back together. Avoid the codes by plugging the sensor in when the car is on - or just clear them if you have and obdii scanner that does that. Also note that Honda's service manual state to avoid getting cleaner in the throttle valve bearing area because there is lubrication in there that can be washed away.

Jim Trainor yup I had my wife put the pedal down to open the butterfly sprayed on a rag and cleaned the throttle body... put it all back together started the car and got a MAF sensor code... rest the code idle and everything runs smooth

[@billn9n]

I did this and the Idle is not jumping after I let go of the gas. Any idea? I didn't take it off just cleaned with the value open as u said.

[@jptrainor]

@@billn9n Give the car time to relearn the idle. Honda says idle relearn takes five minutes after the car is warmed up to operating temperature. Leave lights, ac, and fans off (anything that loads the engine at idle) while it relearns. If that does not do it then I don't know.

[@billn9n]

@@jptrainor OK I will try again. Should I do the relearn as shown in videos with holding the rpms to 3k for 3 mins and what not?

[@jptrainor]

@@billn9n The 3k rpm for 3 minutes is to warm up the car. I don't think it's really critical that it be exactly that as long as the car is warmed up before you leave it to idle. But the car does have to be warmed up to operating temp to relearn the idle. Honda's normal cold idle is around 1500 rpm when you first start the engine. It drops down to 650 or 750 rpm as it warms up. The exact warm idle speed depends on the engine and your location. Colder climates have a higher warm idle.

Great Video! I did it yesterday and the video was a huge help. thanks

[@UCARby]

Thanks. Glad that it helped you

[@jmadelacruz]

Can we do idle learn without the honda diagnostic system app? thank you!

[@StandFastable]

Are you fking kidding me it's so much easier on plenty of other cars 😩

[@guyelsenburg9196]

Yeh i think its a shop job for me lol

[@mr.superstar7919]

You can do it yourself without removing the whole throttle body

[@rTravtrj]

I've always heard you should never spray the cleaner directly into the TB and only onto the towel. I have a 9th gen so if it's different for the 8's please let me know

[@szilvipeter7876]

How do you connect the laptop to the car?

[@shamanjitsingh7267]

Please share the software and equipment used for idle learn procedure.

Hi your video was helpful where did you get the honda program is there a way to get it will it work with any computer on any os?

[@nipsey3221]

Replaced Pcm Now It’s Saying I Need Idle Relearn Will This Help ?!

[@Trojak91]

Hi can you tell me what interface hds you using I'm trying to buy something to my civic 2009

[@marktoth8235]

Can you do this with other programs? Can you connect lets say a delphi obd2 with this program?

[@PericoDeLosPalotes-z7i]

Thank you!.

[@user-qc7hr4my7r]

Will cleaning throttle body fix a tps sensor code?

[@Gary_Fergusons_Lover]

It can. Just clean the rim of the plate and where it sits in the housing.

[@kainhall]

No

[@nikoslagis]

Very good video ! Where can we find the Honda Diagnostic System and obd2 interface , i guess honda is not selling them on retail .

[@UCARby]

Thanks! Sorry for the late reply. I've used chinese copy of this device, which I ordered here: www.aliexpress.com/item/2014-Newest-Version-V3-012-023-for-Honda-HDS-HIM-Diagnostic-Tool-with-Double-Board-HDS/1838749350.html

RoadRiveR thank you very much! Going to order one !

[@nobilitas16]

+RoadRiveR does that software have access to vtec, fuel injection, etc?

[@mkrp4]

My crazy neighbor ordered this software to change a key code on my car 2007 Fit (so I would not able to start it). However his software was fake and counterfeit (made in his native country) and it did not work. As he was trying to figure out why, the cops arrived. They confiscated his laptop and master keys. (He was not arrested because of mental illness)

[@sumdooky]

Do what now?

[@rodniejorge1922]

Greetings, question: Does the throttle body of the 2007 honda civic have the IAC valve integrated?

[@fzghbkhvgfhhgv3524]

Did u ever get your question answer , I’m thinking about cleaning the IAC on my 2006 civic also and don’t know if it has it

[@kainhall]

Electric throttle body's usually just crack the butterfly open for idle air control . But I'm doing this job... I'll reply back in an hour or 2 to let ya know . If I don't reply.... their is NO iac valve

[@fzghbkhvgfhhgv3524]

@@kainhall Thks bud

[@kainhall]

@@fzghbkhvgfhhgv3524 no IAC.... just the EVAP purge valve and butterfly . Helped a TON on this car . Also, I didn't need to remove any of the wiper panel stuff.... but I work on cars for a living (so small spaces aren't a big deal)

@@fzghbkhvgfhhgv3524 also... I'm 6 foot 5 So to save my back.... I just got on my knees . WAY more comfortable Just don't let your shop buds see ya . Might get some "ya practicing??" Comments LOL

[@thomasmanges3891]

The air cleaner housing has a bolt in the top left, it doesn't appear to be for a socket of any kind. Does it just pop out? Or how did you remove this?

[@PEN1_Ontario_909]

Thomas Manges it's a damn rivet with a rubber seal I pulled mine off but couldn't get that rubber seal back through when I put it back on... i said fuck it pushed it down and put the other 2 bolts on

[@kainhall]

@@PEN1_Ontario_909 use a little white lithium grease or oil on it . Pops right on

[@unknwnoutcast4388]

Is this process need it also for a 2006 4 door?

[@shivaan3000]

Yes

[@markbautista7660]

Does the relearn procedure apply to a 2007 crv?

[@E_P1]

английский русскоговорящего годаздо понятнее)

[@LuisRodriguez-bn8be]

I have done this with a scanner tool and my idle goes around 750. But whenever I turn off the engine, and turn it back on it comes back to around 900. I do the reset with a scanner and the relearn just like you show on this video, but never seems to work after I turn off the engine.

[@tommyboubou]

it’s normal it’s post start idle

[@kainhall]

After you start...it will "high idle" for a few mins . It's warming up the cat and o2 sensors . After a few mins / After temp warms up It will drop back down

[@Trojak91]

Hi I do throttle reset without cleaning but hds shows all time time idling relearn is complete.. do I need to reconnect and clean throttle first ?? Another question is what is a standard idling rpms ? On hot engine ? I have something like 650-679 rpms and my car shakes a bit on idling. Thanks for your answer;)

[@thephoenixcycle8854]

I think this is probably what my Honda needs because when the air conditioning is on at idle, like at a stoplight for instance, the car shutters the revs drop momentarily in the car feels like it's going to die. It hasn't actually died yet but it's very disconcerting. After watching this video. This is not for the home mechanic. At least not this home mechanic

[@AudreysKitchen]

Hello. I was wondering if you had work done or got this figured out. Thanks

[@Dada-gk9ic]

Did you manage to solve your issue??

[@kevinward7498]

Holy shit, all that just to clean a little gunk off the throttle body and valve? I miss my CRX! Computers weren't made to simplify our lives, but to complicate them apparently.

[@idrisb07]

The lack of room under the hood of this car is ridiculous

[@UCARby]

Totally agree

[@jaustin8421]

Or use cleaner spray and no need to remove half this stuff!

[@prestondarnell95]

What's the link to the website

[@cloud-ny5ux]

could you feel any boost in performance?

[@UCARby]

Probably I felt just a slightly faster response of the engine when pressing the accelerator pedal. But now I think it was just a placebo effect))

[@kainhall]

It's not gonna make more HP . Just idle smoother

[@dd___dc]

Y do u have to do a relearn idle positions

[@kainhall]

Because if you dont...it will idle too high or too low

[@ROMA2MECANICA]

How much is that computer

[@AndreiGog]

And they say BMWs are complicated haha

[@ivands7249]

Who says bmw are complicated? They're pieces of shit, not complicated at all 🤣🤣🤣 lil honda would outlast that pos still...
