Here is the text of the TSB:
INTAKE AIR VOLUME LEARN WILL NOT COMPLETE APPLIED VEHICLES: All
APPLIED DATES: 2007 - 2012
SERVICE INFORMATION
If IAVL will not complete using CONSULT:
a. While the engine is running, disconnect “Mass Air Flow” (MAF) sensor for 10-15 seconds until MIL (P0102 or P010C) comes on, and then reconnect before performing “Intake Air Volume Learn” (IAVL).
• If vehicle has two MAF sensors, disconnect only one in prior step and leave the second one connected; then reconnect.
• Engine may stop running when idle reduction occurs. Reconnect MAF sensor and continue to step “b”.
NOTE: If P0102 or P010C were not stored when DTC was confirmed, repeat step “a” until idle is reduced.
a. Clear any DTC’s that may have set during MAF disconnect.
b. Perform IAVL.
c. Confirm that idle is now within specification for model and year of vehicle being worked on.
Did not work on g35 '07 sedan
Hey A Sea Rhinocerus,
There is a bug in the 2007 G35 and 350z ECU and the idle air volume learning will never run to completion.
Some have been able to get an ECU update at the dealer, or you can it updated by Eugene at Enthusiast Auto Care
(www.yelp.ca/biz/enthusiast-auto-care-concord)
One 350z viewer commented that he replaced his ECU with one from a 2007 350z.
Love your channel. It's extremely informative and it has saved me a lot of time and money.
Hey Veritas707,
Thanks for your kind words about my channel. I am glad it has helped you.
I cleaned my throttle body in my 3.7L Q50, had the high rpm issue. I tried the manual way 3 times. Wasn't having luck, but got the VP11. I had done the first two procedures in the morning, drove to from work, parked in driveway and ran the IAVL. It went to about 4000 in the NDS3 app, took well over a minute, and said it failed. Engine reved quiet a few times during the process but didn't return to 650 after restart. Ran it two more times, each seeming to fail. Next day though, I had to drive to work and its started idling between 600-650 after warming up. So I have no clue how it started working but YOU ARE THE MVP! Running like a champ, cant wait to do more DIY! Leaving this book here in case someone else runs into the same weirdness I did ;)
Nice! I'm glad you got it to work. The idle air volume learning can be tricky to get to run... The NDSIII app makes it soooo much easier :)
This worked perfectly the first time. I was nervous after cleaning the throttle bodies and getting the high idle. The car drove horribly. After doing the two manual relearns and this app relearn, everything is great. Absolute at .78, relative at 0 and idle at 650rpm. Thanks for what you did here.
Wonderful!! I'm glad you are happy. :)
Best videos, thank you from Russia!
Glad you like them!
Thank you! Fixed the high idle on an Infiniti QX56 after cleaning the throttle body.
Thanks for letting me know... It makes my day :)
Oommgggg, thank you so much. I’ve done the manual idle relearn a few times, and it always takes me around 10 times before she purrs like a kitten hahah
Thanks again
Hey muasboy,
I know exactly what you mean, I have also tried multiple times to get it to work, BUT this app makes it very easy!
Thank for your time
Anytime :)
Thanks!!
Hey itsmistersmoke,
You are welcome :)
Hello MotorvateDIY, I have a 2011 G37S Coupe but am not able to get the Idle Air Volume Learn function to enable as (turn green). I noticed when connecting the Status bar does also reads Get Params Failed and Get Regs failed as well. What do you recommend???
excellent thank you !! im going to get the Bluetooth scanner
Great! My favorite Bluetooth OBD scanner is the OBDLink MX+, and are expensive at about $80. BUT they have a 3 year warranty and come with a full featured app. (that I use a lot!)
Cheaper options are the VeePeak OBDCheck scanners at around $30-40
Autokcan OBD2 Bluetooth:
At $14 (from amazon.com US) this is also a good scanner:
Good luck with what ever you decide to purchase.
what obd bluetooth scanner did u get? Looking at cleaning my throttle bodys from ur other vid :D
Hey Peter Jordan,
My current favorite Bluetooth OBD scanner is the Veepeak VP11.
It is a fair price, fairly quick in data rate and has a reliable connection.
Hello, great vids as usual!! I was wondering which Bluetooth scanner you used in this video. Would really appreciate a reply thanks!!
For that video, I used a Veepeak VP11 Android only Bluetooth scanner.
Helped me out. Thanks. What's the difference between the paid version and the free lite version?
Hey John Zhu,
That's nice to her!
Off the top of my head, the paid version allows you to record video and overlay the gauges.
I think if you touch the video tab, a note pops up and explains the additional features.
Derek! I let the engine idle for 23 minutes without driving.
Before running Idle Air Volume Learning, the battery bolt is 11.8v to 12.0v.
After running Idle Air Volume Learning, you will get 14.0v.
It doesn't matter?
I captured the display screen, but I can't attach it to the comments~~~
Hey 이성원,
I think that should be fine.
Hi, Derek.
How have you been?
I have a question.
Before learning Idle Air Volume
Should I reset the ecu?
Hey 이성원,
There is no need to reset the ECU.
hi! will this work with my nissan grandeur qg16 engine? after i cleaned my throttle body and aicv i had an erratic idle. thank you...
Hey Oreo milk,
To be honest, I have no idea.... All of my documentation is for North America and a little of Europe.
If the QG16 has an electronic throttle, there is no harm is trying this.
Please let me know if it works.
Hey..man..with this app nds3..have you tried to do the vvt learn..did it work?..just wondering ..
Hey li san
Do you mean the "Exhaust Valve T/C Learn" that is for the VQ35HR engines?
I have not tried it, since I have the VQ37VHR.
The NDS III app seems very good and I would trust it.
Here is the description from the factory shop manual:
Exhaust Valve Timing Control Learning is a function of ECM to learn the characteristic of exhaust valve timing control magnet retarder by comparing the target angle of exhaust camshaft with the actual retarded angle of O exhaust camshaft. It must be performed each time exhaust valve timing control magnet retarder is disconnected or replaced, or ECM is replaced.
My manual 6mt g37 has no check engine lights but the rpms spike or fluctuate when I press the throttle a bit hard. Just changed spark plugs and cleanes tbs
Have you done the idle air volume learning?
Normally this gives a smooth idle.
Will BlueDriver’s bluetooth OBD work with the NDS android app?
As far as I know, the BlueDriver OBD only works with their app.
NDS requires an ELM327 compatible OBD scanner, so you may want to pick up a cheap ELM327 scanner :)
Should I do a relearn if I have put spacers on my throttle bodies?
Hey Alien8eD!,
That is a great question!
Since the throttle body spacer doesn't change the airflow at idle, I don't think it would be necessary to do the "idle air volume learning"
However, since the throttle bodies are off, why not clean them and do the "idle air volume learning"... then you are good to go for a while :)
Where can i buy a Bluetooth scanner? And what brand did you purchase? I was told by the app to buy a v1.2 or v1.4 b cause 2.1 are fake
Hey dgree100,
For this video I used a "Veepeak VP11" from Amazon. It works well with NDS III Lite, Torque Pro, Torque Lite and OBD Fusion.
I noticed that you used the elm327 module that was NOT recomended by NDS in their supported modules page, yet it works for you. Can you link to the company you bought your module from?
Hey Prestor John,
Sorry, but by accident I have misled you.
The ELM327 module shown in the video was not used with the app. It was an existing video
from another episode.
The adapter that was used and worked very well, was a Veepeak VP11.
Hi do you have the links where did you buy the veepeak vp11? Thank you.
Yes
Hey Lamberto Lopez,
OK, that's good.
I don't know why the slip and vdc light are on, but let's try to get the idle down to where it should be.
What car are you working on? (Year, make & model)
Have you tried this:
www.370zcoupe.com/TSB/1TN39.PDF
hello, i have a question..will the ecu relearn by itself? i changed plugs,cleaned throttle bodies and maf sensors and started car up and was idling erratically up and down a few times before doing it all over again...i did the IAVL and it stabilized the rpms alot lower (800 to 900 rpm)...while in drive and stopped its normal but coasting to a stop it idles around 900rpm...will it fix itself? over the course of days of driving?
Once the engine is fully warmed up, the idle should be between 600-700 RPM when in park/neutral.
I don't know what is normal engine RPM once it is in drive and costing to a stop, as my G has a 6 speed manual.
You could ask you question on www.reddit.com/r/G37/
thanks for the reply. i got it back down to normal with the last proceedure of the three..your videos are very informative and helpful. keep up the great work 👍

Failure to set Idle Air Volume Learning
To what temperature does the vehicle's engine have to cool down to?
Hey 이성원,
The engine coolant temp must be at least 70C.
In order for the idle air volume procedure to run and complete
Make sure that all of the following conditions are satisfied:
Learning will be cancelled if any of the following conditions are missed for even a moment.
• Battery voltage: More than 12.9 V (At idle)
• Engine coolant temperature: 70 - 105°C (158 - 221°F)
• PNP switch: ON (M/T models)
• Selector lever: P or N (A/T models)
• Electric load switch: OFF (Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is started the headlamp will not be illuminated.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
• Drive vehicle for 10 minutes.
My BT Ali adapter works with Scanmaster PC Win10 also with Car Scanner 1.45.6 Android But the Niss Data Scan application does not connect
Hey Luky ZorrroS,
You may want to have a look at the supported scanners on the NDS website:
nisscan.com/NDSIIA/index.php?content=supportedadaptors
Nissan DataScan emulates the Consult III protocol and not all scanners have the hardware to do that.
Derek!
throughtle closed learn.
Number 2. How many seconds do I have to wait after the switch is on?
Or is it off right after it's on?
1. Make sure that accelerator pedal is full.
2. Turn position switch ON.
3. Turn position switch off and wait at last 10 seconds.
Make sure that you want to do something.
Hey 이성원,
This video explains everything step by step :)
ua-cam.com/video/HIiaF0VaTlQ/v-deo.html
@@MotorvateDIY The manual says to switch on, and Derek's UA-cam says you should start the car, turn the water temperature to 67C, turn it off, and listen to the throttle body closed. Don't you understand?
Hey 이성원,
I am not 100% sure if I understand the question...
Here are the steps right from the shop manual:
WITHOUT CONSULT-III
1. Start the engine.
NOTE:
Engine coolant temperature is 25°C (77°F) or less before engine starts.
2. Warm up the engine.
NOTE:
Raise engine coolant temperature until it reaches 65°C (149°F) or more.
3. Turn ignition switch OFF and wait at least 10 seconds.
Check that throttle valve moves during the above 10 seconds by confirming the operating sound.
Will this procedure work on 2017 Honda Accord?
Sorry, but no... This is only for Nissan /Infiniti vehicles.
@Motorvate DIY Just to clarify, the engine should actually be running, right, not just in the on position?
Hey GeePeeZee,
Correct ! BUT please make sure the "pre-conditions" are met. See Episode 27 for all the details :)
In the other video, you mention putting the parking brake on in order to disable the DRLs. I have an automatic and the IAVL process with NDSIII failed every single time until I set the parking brake so it seems that it needs to be on anyway, along with the other conditions.
Hey Hall Stevenson,
Good to know... Thanks for the comment!
Derek, do you have another question?
Do I have to do a Pedal Releasescl rear and then continue to do a trot closecl clear?
Or do I have to do Pedal Relegasecl Erlen and wait until then do throttle closecl learn?
As I said yesterday, idle speed is maintained at 650 rpm,
If you take your foot off the accelerator when you are driving slowly and when the vehicle is blocked, you can quickly fall to 500 rpm.
I can't figure out why.~~
We can't even replace it with a throttle chamber, air flow sensor, pcv valve, ignition plug, ignition coil.
It's falling to 500 rpm, and there's a slight engine break.
I don't know the reason at all
Hey 이성원,
Sometimes getting the "Idle air volume learning" to run can be difficult. EVERY action mentioned in the video must be followed.
So, yes, do the pedal released learning, throttle valve closed position learning and finally the idle air volume learning.
When you use NDS III to run the idle air volume learning, does it complete?
The same symptoms appear in the stomach, even though the execution has been completed with NDS III.
Do I have to do key on 1 second when I study throughtle closecl learn?
Hey @@user-pm7pp5xk6x,
It looks like "google translate" isn't working well for your first sentence... I don't understand what you are asking.
When you use NDS III to run the idle air volume learning, does it complete? answer - Running NDS III is complete.
Closing the throttle valve When learning, can I just turn on the key for one second?
Hey @이성원,
If the NDSIII Idle air volume learning is "complete" you are done and and turn off the engine.
Hey!! I'm disappointed with the app. I have a Nissan March with a 1.6 HR16DE 2013 engine. I installed the app on my phone with Android 14 and the main function I needed didn't work. Idle Air Volume Learn (IAVL) function.
The button is not enabled for use. Can you explain to me the reason for this? I installed the NDSIII Lite version.
It looks like NDSIII doesn't work with your engine:
nisscan.com/vehicles/?v=3e8d115eb4b3
However, NDSII does list "FRA Nissan Note 2008 (HR16DE) - ECM"
You may want to reach out to the niscan.com folks for support.
If the original idle air was learned and stored in memory why does it need to be relearned? Or is it stored in RAM.
Hey Fernando Hood,
That is an excellent question!
Due to the crankcase ventilation (PCV system) there is a little oil in the intake air. This is why the throttle body gets dirty.
Over time, the ECU will adjust the throttle position (little more opened) to compensate for the carbon build up. When we clean the throttle body and remove the dirt, this will allow MORE air into the engine and the idle will be higher.
The idle air volume learning process allows the ECU to "reset" the throttle position to get the proper idle speed.
The idle air volume values are stored in non-volatile memory, so they are not lost when the battery is disconnected.
Hey I got the app and the scanner you used but I keep getting "ini failed" not sure how to fix this. Hoping you can help!
Troubleshooting over UA-cam messages is tricky... but I'll give it a shot.
Does the OBD scanner work in other OBD apps?
What year, make model is your car?
The NDSIII Android app only works on 2009+ Nissan/Infiniti vehicles
@Motorvate DIY hey no problem, I actually figured it out yesterday! My phone isn't compatible with nds iii so I was using nds ii but my car is 2016 and nds ii is only good for up to 2009 so I was out of luck in that part but I found a work around for getting it on windows for my laptop and now I'm waiting on an obd scanner for my laptop to come in the mail. Here's to hoping it all works out!
Good troubleshooting!!
Good luck on the next steps and please let me know how you make out.
What does the clear self learn do?
Hey dgree100,
What an EXCELLENT question!
Our engines are always adjusting how much fuel they need to run properly. This allows the engine control unit to compensate for wear.
These adjustments are called "Long Term Fuel Trim" and "Short Term Fuel Trim"
If you add both together, the result is the total fueling requirements of the engine.
Here is a video I made for my other channel that will explain it: ua-cam.com/video/E6BWhp3851M/v-deo.html
When the "Self Learn" is cleared it resets the "Long Term Fuel Trim" back to zero.
The "Short Term Fuel Trim" is reset to zero every time the car is turned off.
The "Long Term Fuel Trim" is saved in a special memory that isn't erased when the car is turned off.
What does the clear self learn button do ?
It clears the long term fuel trim.
Hi, Motorvate's
Do you have any questions?
Manual setting is 10 minutes when you are an automatic car.
If I use the app, can I learn the IDie air voome for 10 minutes without driving?
What is the engine coolant temperature?
Thank you.
Hey 성원 이,
In order for the engine oil, engine coolant, and transmission oil to be at the proper temperature a 10 minute drive is required. Idling for 10 minutes may work, but it is best to go for a 10 minute drive.
The engine coolant temperature needs to be 70 - 105°C (158 - 221°F)
and here are all the required precondition required for the idle air volume learning procedure to run and complete:
Learning will be cancelled if any of the following conditions are missed for even a moment.
• Battery voltage: More than 12.9 V (At idle)
• Engine coolant temperature: 70 - 105°C (158 - 221°F)
• PNP switch: ON (M/T models)
• Selector lever: P or N (A/T models)
• Electric load switch: OFF (Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is started the headlamp will not be illuminated.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- A/T models
• With CONSULT-III: Drive vehicle until “ATF TEMP SE 1” in “DATA MONITOR” mode of “A/T” system indicates less than 0.9 V.
• Without CONSULT-III: Drive vehicle for 10 minutes.
- M/T models
• Drive vehicle for 10 minutes.
Thanks!!
Anytime :)
Thank you very much motorvate diy
Do you have another question?
- A/T models
• With CONSULT-III: Drive Vehicle unit undtil "ATF TEMP SE 1" in "DATA MONITOR" mode of "A/TITOR" system
Does this mean transmission fluid temperature above 80°C?
Hey 성원 이,
The factory shop manual doesn't mention a specific transmission oil temperature.
If you can't drive the car for 10 minutes, then I think the next best thing would be to let it idle for 15 or so minutes and then do the idle air volume learning.
Good luck!
What bluetooth OBD scanner do you recommend?
For the NDS III app to work, any cheap "Classic bluetooth" or "Android only" adapter should work.
Here is one example: www.amazon.com/Bluetooth-Detector-Automobile-Diagnostic-Suitable/dp/B08V95PDQX
@@MotorvateDIY thank you!!
Hey! Derek.
When I set up Easy Idle Air Volume Learning, I have a question.
#One day, when Idle Air Volume Learning is activated, the reaction of the Alphiem and the engine will be completed and the battery bolts will be 11.8v to 12.0v.
#One day, when Idle Air Volume Learning is activated, the battery bolts are set to complete without any reaction from Alphiem and the engine (then the battery bolts are 14.0v to 14.2v)
I don't know if this is the right setting...
Hey 이성원,
I am really sorry, but I don't understand what a "Alphiem" is and can't understand your question.
Hey Derek
I am really sorry.
I think my question is wrong.
1. During Easy Idle Air Volume Learning, there are times when the engine RPM moves up and down and becomes set (at this point the battery voltage is 11.0v to 12.0V).
2. During Easy Idle Air Volume Learning, the engine RPM is set without any movement (at this point the battery voltage is 14.0v to 14.2V).
1.2 Do you want to know what's right about the bundle?
Hey 이성원,
Thank you for re-word the question, I think I understand now :)
The ECU controls how much power the alternator generates and that is why the voltage changes.
If you let your car sit all night and measure the battery voltage in the morning, what is it?
Using NDS III does the idle air volume learning complete?
@@MotorvateDIY I tested two methods under the same conditions.Setting using NDS III will result in engine eddy. If you set the existing factory manual method, there will be no defect. You don't know why?
Hey 이성원,
Sorry, but I don't understand what you tested: " I tested two methods under the same conditions."
What does "engine eddy" mean?
That works rpm going down .two light slip off VDC and I push de pedal rpm doesn't respond until 1800
Hey Lamberto Lopez,
I am sorry, but I don't understand what the question is. Please try asking in a different way.
My Rpm’s is rising up and down rapidly, it also just keeps on saying ECU busy. Is there a way I can contact you please ?
That sounds like the ECU is trying to lower an idle that is too high. Please scan for codes and see if you have a P0507 (idle too high)
It can be tricky to get the idle air volume learning to run to completion. Some of the comments on this page mention trying it over 20 times, before it worked. Kind of weird.
BUT you do need to follow the pre-condidtions exactly, if anything isn't correct, it won't run to completion.
Is there no other way to do this without a scanner?
Hey Jonah urban,
Yes there is! Here is a link to that episode:
G37 & 370Z After Throttle Body Cleaning: Motorvate’s DIY Garage Ep.27
ua-cam.com/video/HIiaF0VaTlQ/v-deo.html
I have low idle after doing the idle relearn, would you know why ? I don’t have any codes.
How low is low? What engine / car?
@@MotorvateDIY 2011 g37x and it’s at 500 when I put it in drive.
Idle speed is measured in park or neutral, with the engine fully warmed up.
With the transmission in drive, it is normal for the RPM to drop a little.
To me, it sounds like it is normal.
@@MotorvateDIY ok thanks
I followed the instructions but they two signals in a car dashboard slip off and vdc the pedals not respond only 1800 rpm sorry for that
Hey Lamberto Lopez,
Let me try to understand:
• The "Slip Off" and "VDC" dash lights are on.
• After cleaning, your idle is 1800 RPM
• The gas pedal doesn't make the engine rev
Ami close?
Hi, will doing this remove the check engine light that is currently displayed on my dash ?
There are 100s of reasons why your check engine light is on. Scan it to get the trouble code, and troubleshoot from there.
The check engine light will go out on its own, once the issue is fixed and the car completes 2-3 drive cycles. (google it for your make and model to see what it is)
@@MotorvateDIY sorry for being so vague. I cleaned my throttle body recently and the check engine light came on because of that. If I do the idle relearn, will it remove the light ?
What was the code?
@@MotorvateDIY there is no code, only the light is on and it came on after I cleaned the throttle body.
If the check engine light is on, there is a code. Maybe the OBD scanner didn't pick it up?

It looks like you need to use the 22693-EY00A A/F sensor.
So you mean you can't use it?
Infiniti says the parts are not interchagneable, so I don't think so.
The sensor output could be different, or maybe the connector.
Eric, thank you always. I thought that the engine and horsepower of the 2008 G37 Coupe and the 2008-2009 G37 sedan were the same, and the sensor looked the same, so the a/f sensor would be the same. It's been working and it's been fine for a few days, but I got some engine trouble when I was at idle after driving. I need to get it out.
Hey 이성원 이,
Before you remove it, can you retrieve the code? A cheap OBD scanner ($15) and app (like OBD Fusion or Torque Pro) would allow you to see the actual trouble code.
Then we can have a look at this together and see if the code is A/F sensor related.
There is a small chance that sensor might work.
I don't know if Idle Air Volume Learning setting has failed.
Repeated stop start during slow and traffic jam.
If you step off the Axel Paddal, it quickly drops to 500 RPM, and as soon as you return to normal, your car will experience some trouble.
Idle is normal at 650 rpm.
Hey 이성원,
It doesn't seem like the idle air volume learning has completed.
It only works when ALL the preconditions are followed exactly.
See the reply below.
I don't think all the preconditions are complete and working.
However, when the m37 engine is started, the battery bolts move from 14v to 11.8v.
It is maintained from 11.8v to 12.0v
It is not conditional on 12.9v. Does this matter?
And I always set Idle Air Volume Learning
The temperature of the engine cooling water is higher than 90c and the automatic gearbox oil temperature is 70c to 80c.
Hey 이성원,
In order to increase the fuel efficiency, our cars control the power output of the alternator
So, the traditional voltage output ( 14+ volts engine running, 12.4+ volts with engine off) can't be used to determine if the charging system is working properly.
If there is high idle e.g 1500rpm will this work?
Hey Fernando Hood,
First check: Make sure the engine is fully warmed up. a 10-15 minute drive should be good.
If the idle is too high, the idle air volume learning won't run to completion.
To temporarily lower your idle, you can create a small vacuum leak by unplugging the PCV system at the intake, or by allowing a little air in at the throttle body. (Loosen the clamp and partly pull off the rubber boot until there is a little opening.
Others have had luck by unplugging the MAF, starting the car and getting a check engine light. Then plug in the MAF, clear the code and the idle might be a little lower.
@@MotorvateDIY I tried unplugging the maf and the rpm remained unchanged. I thought more air equals higher idle.
This engine (VQ37VHR) is very smart. It has the ability to run without the MAFs connected. (at idle anyways) It converts from a mass air flow based system to speed density.

Did you try the steps in this document:
• www.370zcoupe.com/TSB/1TN39.PDF
Did it work?
What are the downside of not doing this process?
A high, unstable and rougher idle.
It keeps on saying ecu busy for like 10 min lol
That's odd... Are all of the per-conditions met?
@@MotorvateDIY I just did all of them again it worked 😅 thanks for the easy guide
I'm glad you got it to work... They can be tricky!
Enjoy your smooth idle and improved initial throttle response :)
did not work
Hey Lamberto Lopez,
I'm sorry, but I am out of ideas. You best option is to take it to a mechanic and have them scan all modules on the car's network.
Good luck!
