Preparation

Before performing Idle Air Volume Learning, 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 12.9V (At idle)
Engine coolant temperature: 70 - 100 C (158 - 212 F)
Park/neutral position (PNP) switch: ON (Shifter in Park or Neutral)
Electric load switch: OFF (Air conditioner, headlamp, rear window defogger)
Steering wheel: Neutral (Straight-ahead position)
Vehicle speed: Stopped
Transmission: Warmed-up (Drive vehicle for 10 minutes.)

Operations Procedures

1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 second.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.
If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.

Accelerator Pedal Release Position Learning
Operation Procedure

1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds.

Throttle Valve Closed Position Learning
Operation Procedures

1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch to “ON”.
3. Turn ignition switch to “OFF” wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound.

Idle Air Volume Learning (Throttle Position Learning)

It is better to count the time accurately with a clock.

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Confirm that the accelerator pedal is fully released, then turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

Nissan Electronic Throttle Body (ETB) Re-Learn Procedure

[hillbobaggins]

Don't even need a stopwatch. You provide one! Haha. I followed everything you did in real time and it worked flawlessly. Thank you!

[drewutube]

Timing is the most critical step in the relearn process, and your tutorial was on point. I have successfully completed my electronic throttle relearn.

[jkthomas]

Just bought my 06 Infiniti G35 and had a high idle. After tune-up, oil change, air filter, intake hose and boot. I watched your video and voila!! I'm at spec. Really appreciate the tutorial. Please keep making videos that's very informative. Thanks for everything.

[brents]

You have no idea how helpful this video was!!! I tried about 3 of the other ones and they didn't work for me. This one worked and the process was easier too.

[jonrivera]

Sir you are a brother in arms. I did this to both my Z's - '12 sport tour, '16 nismo. They run noticeably smoother now, and actually identical to a brand new '20 base model one of my buddies just got. That gives me all sorts of peace of mind

[chrisd]

4 years later still helping people out! Thank you bro I just bought an 05 g35x had a few issues but all was fixed except the idle, this vid did the trick, thanks again im subbed.

[RicardoRodriguez-prwj]

After cleaning the throttle body on my 2005 Nissan Frontier V6 4.0l my idle went out of whack. The relearn worked the first time I tried it. I did it right beside your video and I didn't even have to look at my check engine light blinking. Timing is everything. Thanks!

[letsgetcookin]

Wow man, this really helped a lot. I recently finished fixing up my 2006 g35 coupe and realized that it the idle was being very weird. It jumped from 600 rpm’s to 1000 back down to 600, and made the car annoying at times. I found this video without realizing I had to relearn the idle, since I did remove the throttle body to replace valve covers. This video helped a lot and I just finished the relearn.

[PLATINUMU]

You saved me right at 200 dollars!!!I had replaced my throttle body with a new one. My car has 375k miles.. I was just gonna give up on it. But your video will be the reason I won't give up on my Altima.. Thank You!!😇😇😇

[Basshunter]

I tried this method on my FX35 and it worked like magic. Thank you very very much for making this video!!!!

[martyvee]

Thank you for making this process much more interactive! you made it easy. Thanks for taking time! This would be my 3rd time resetting it and you simplified it. Blessings

[Fresh]

Just replaced a crankshaft and tranny, and couldn’t figure out why the car was rough idling. Remembered your procedure, and she’s fixed! Thank the Lord, she’s fixed!!!

[raidenjr]

Boooy u're a star .. I had a high rpm on idle & the check engine light was on. So I followed ur procedure & it worked .. It went back to normal & the check engine light disappeared .. Thank God & thank u .. Definitely thumbs up 👍

[gs]

I cleaned the throttle body on my 06 G35x (107k miles). After doing so, I noticed that the rpm was a bit higher than usual on decel and idle. The car would propel itself and maintain speed on its own if you caught the rpm at the right time around 1300. After doing this the idle immediately went back to normal and the car decels normal. Thanks as always, your vids are easy to follow, informative and entertaining. Been watching for 4+ years :)

[garyantillon]

WHOS HERE IN 2020 HELL YEAH BROTHER BACK IN BUZINESS GOT MY G35 RUNNING RIGHT GOD BLESS

[ferretpunk]

My car was idling so badly and would die out after changing my camshaft sensor because I was messing with the throttle body. This fixed my issue in 2 minutes. 2003 350z, thank you!

[depsqu]

You made it so easy to do the re-learn appreciate that. M35 is back to normal🙏🏾

[ricco]

I found an even EASIER way to reset my throttle position sensor and idle air settings. I removed the Cable from both neg and positive posts. I REMOVED the throttle connector(s) on the HR models 07-09. And I waited 30 minutes. I reconnected the battery cables. Then I reconnected the throttle body connectors. I started the car up and the throttle was RESPONSIVE AF and the Idle was back to the right position.. I Believe it worked for the ECU too.. My check engine light was cleared as well.. Been 3 months and it's still going smooth

[julianpedro]

Thanks!!!! The only version that really works, you save me, I bought many car parts to solve it and it was only a simple relearn

[StandYourGrounds]

Hello.
2009 Murano here. Did everything, light did blink and then went solid but it didn't go away at the end. Light came on after cleaning throttle body.
EDIT: Tried once more after this and it did work. Light went away. Timing is the key. If you do this than you have to be super precise. Thank you Motordyne for this video!
