After my (authorized) service station has cleaned my throttle body the car is idling higher than normal (~900rpm - 200rpms higher) and the car is accelerating by itself (without pressing the accelerator) when rpms are lower than 1500! They have reseted the ECU and did the idle learn procedure but the Honda computer still reports that the "Idle Learn" as "not completed".

They have also replaced the whole throttle body with a new one but the issue continues...

I have done a lot of km/mi since then and the mechanic seems not to have a clue of what is going wrong...

Anybody here which had this issue?

TIA

2008 CR-V 2.0 Auto 4WD

 

The problem has been RESOLVED AT LAST (after 2 months...) using the method that is described below: you have to reset the TPS sensor with the Honda computer. After that the Idle Learn procedure started normally and was completed shortly after.


"ok so to everyone who has this problem i want to stop the insanity of hearing people replacing good throttle bodies and some saying the dealer has to reflash your pcm.. in some cases if you man handle your throttle body you could damage it but jeez im sure you guys are being careful RIGHT? So that being said im a tech and have been in the automotive trade over 25 years doing electrical diagnosis and tune up so when i cleaned my throttle body and my car started acting this way i naturally needed to find out why... first thing i did was a idle relean which did nothing n i did it 4 times..so i hooked up the scanner and looked at all my pid's n low and behold the tp sensors were not agreeing so i went into special functions on the scanner and did a tps calibration..fired it up and idle went down to 750 perrrrrrrffffffect...the rev hang was gone or back to normal cause as all of us know these 8th gens do that on factory tune.. unfortunately this action has to be done by the use of a scanner and no it doesn't have to be a hds from honda it could be any good scanner with bi directional controls a $100 scanner from the parts store wont work...so if you clean your throttle and notice your idle stays at 900 rpm and when you come to a rolling stop in neutral your rpms shoot up to 2500 rpm till you come to a complete stop or you use your front window defrost and throw a p0507 "idle higher than expected" all these problems are caused by the same problem "TPS CALIBRATION" to all of you that went to honda and they couldn't address this problem its a shame cause they should know this..Now i know people are saying the car fixed itself after driving it a couple months or whatever but really can you drive you car with it bucking along while trying to find a parking spot or going to a drive through and you guys that have this know what i mean..it will fix itself after a while but it will take a long time for the pcm to learn all the values needed..hope this sheds some light guys...peace."

 

Man I have a snapon verus , I am going to see if I can use that for the tips recalibration? And I also have an old Honda HDS , but I believe you said that won't do it? I will try with the snap on...thanks will let you know if it works..

 

Dude you are a life saver , take a thud lol.. I connected my Snap on Verus , found the TPS Calibration button and followed thru to a sweet idling 650 + or -5 rpm's.. It is running like she did when I first got her , even though I have 195,000 miles on it.. My 2008 CRV.. Someone else has the same issue and I will let them know to seek out your post and take care of the problem he is having with his CRV..thank you and enjoy your holidays..:

 

Would this work as well for an 04 Honda CRV? I am having same issues as above.
