2007 - 2013 Nissan Altima 2.5L Throttle Body Replacement & Idle Re-Learn Guide!

[@quick2review272]

1) Perform the Accelerator Pedal Released Learning procedure. This procedure tells the ECU what voltages to expect when your foot is off the pedal Foot is off the accelerator pedal Turn ignition switch ON and wait at least 2 seconds Turn ignition switch OFF and wait at least 10 seconds Turn ignition switch ON and wait at least 2 seconds Turn ignition switch OFF and wait at least 10 seconds. 2) Perform the Throttle Valve Closed Position Learning Procedure Foot off the accelerator pedal Turn ignition switch ON. Turn ignition switch OFF and wait at least 10 seconds During the last 10-second period, listen to the throttle body to make sure you hear it moving 3) Start the engine and let it run under the temp gauge is in the normal range. 4) Turn ignition switch OFF and wait at least 10 seconds. 5) With your foot off the accelerator pedal, turn the ignition switch ON and wait 3 seconds. 6) Then perform this procedure with the engine off, key in ON position. Repeat the following procedure quickly five times within 5 seconds. Fully depress the accelerator pedal Fully release the accelerator pedal. 7) Wait 7 seconds, fully depress the accelerator pedal and keep it down for approx. 20 seconds until the MIL stops blinking and turned ON. 8) Fully release the accelerator pedal within 3 seconds after the MIL turned ON. 9) Start engine and let it idle. 10) Wait 20 seconds. 11) Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications. Idle speed = 650 ± 50 rpm (in P or N position)

So when u do the relearn, only time u press the gas pedal is towards the end? I got a code reader today and this was one of mine on the list.

[@richbycelly]

Thank you for this tutorial! I was having code P101 and my local dealer refused to change or even take a look at my throttle body because I have a cold air intake installed.

[@TrickShiftGarage]

You're welcome, glad this video helped. You won because you saved a lot of money by doing this yourself 😉

[@richbycelly]

@@TrickShiftGarage Nissan chargers $500-600 just for an oem throttle body that’s 10 years old. They would’ve fucked me on labor

[@TrickShiftGarage]

Yup! That's how much I found it to be when I was shopping around. This Hitachi I bought on Amazon has been perfect so far, smooth driving. Fixed my high idle problem I was having. Thanks for watching bro! 👍

[@richbycelly]

@@TrickShiftGarage do you have any videos on refilling freon?

[@Voidhawk001]

Thanks for these qr25de videos, I have 2011 xtrail in Australia with the same motor and helps a lot

[@amustsuccess]

Thank you for the video. My car (Nissan Altima 2013) works fine in reverse, but does not get past 2 rpm on drive mode. What do I possibly do to fix the problem?

[@TrickShiftGarage]

Well, you can check the fluid level and make sure that is at the right level. Low fluid level could be the cause. Also smell the fluid while you're checking the level. If it smells burnt or looks brown the fluid overheated and needs to be changed out. If none of that is a problem, then you should take it in to a Nissan shop and let them diagnose what's going on. Take it to a second shop if your skeptical and would like a second opinion. Hope this helps, thanks for watching! 👍

[@amustsuccess]

@@TrickShiftGarage I appreciate your swift response. I changed out the fluid and added 8 litres, but still have the same problem. The 2013 NA takes 10 litres of CVT fluid after a complete drain, according to Nissan instruction. So, a 2 litres fluid will be added for proper gauge and would try again.

[@marklewis4664]

Have a 2010 altima push button hw do I do the rest sequence

[@MyQuietRiot]

same thing here, hiccups at 2000RPMs only every now n then... Replaced MAF sensor, reset battery/computer. Still doing it every other drive/trip. EVer figure out what it was?? AIrfilter is new, havent cleaned throttle body yet tho. no obvious cracks/tubes etc... what fixed yours?

[@JamesElizondo-mz7nq]

Would this video work for 2014? I'm not having issues right now but my Altima has 200k so I figured it's time. Thanks

[@TrickShiftGarage]

If your car has the same 2.5 liter engine, I would guess it's roughly the same. I can't say if the part number is the same or not but it can probably be used as a rough guide to replacing the throttlebody. Thanks for watching! 🙂

[@GolgiGuy102]

Does the throttle body still make a noise similar to the relearn noise when shutting your Altima off. I noticed my makes a similar noise when i shut the car off with the hood up. Not sure if it is new or just never noticed it before.

[@TrickShiftGarage]

I'm not sure, I'd assume it probably makes that noise every time the engine shuts off, but like you never really noticed or listened out for it before lol. I'll try listening the next time I drive it! 😉

[@GolgiGuy102]

@TrickShiftGarage Dude! Thank you for the reply, buddy. Yeah, it wasn't something I noticed until I had to work on it lol. Take care :)

[@chadnavaro4894]

If you change just the pedal do you have to do this relearning process?

[@TrickShiftGarage]

I don't think so. It shouldn't mess with the idle quality or speed because the throttle body isn't being unplugged. I'd say try it out and let us all know how it goes! Thanks for watching! 👍

[@chadnavaro4894]

@@TrickShiftGarage yeah I tried it doesn't seem like it matters I think you're right thanks

[@chadnavaro4894]

@@TrickShiftGarage and I ended up doing the throttle body and getting it to relearn was pretty tricky for me it wouldn't take until the last step and what I did I Rev the engine after 20 seconds couple times to about 3000 rpm then the idle just came down and it was just perfect so thanks again for doing the video really really helped

[@Pingaheimer]

do u have to do the relearn if you remove the existing throttle body to give it a good clean but don't replace it?

[@jeremyjones1017]

I have a p0443 evap purge valve and it's behind the engine so hard to get to what's the way to get to it and I have a 2010 nissan altima 2.5 so I watch all the video's

[@erikmaldonado246]

Question, I installed a new throttle body on a 2007 Altima. After installing, idle still fast when transmission is in park and haven’t been successful with relearning process. Any advice?

[@TrickShiftGarage]

Hello, I'd take it to a mechanic and have them reset the idle to normal. They should have a OBD scanner tool to do this. Hope this helps, thanks for watching ☺️

[@nicholasvonrhine6311]

Outstanding.

[@TrickShiftGarage]

Glad you like it and thanks for watching! 👍

[@vickod18]

Question, lets say i cant get it to relearn, will it relearn by itself after driving?

[@TrickShiftGarage]

I've heard that it will (as long as nothing is wrong with it) but I've never seen it before. If it doesn't and the relearn isn't happening, your local Nissan dealer has the computer to relearn it automatically, but they'll probably charge you something for it.

[@vickod18]

@@TrickShiftGarage thank you so much for the response

[@TrickShiftGarage]

You're welcome, thanks for commenting! 👍

[@hopLight2322]

I was wondering. I just bought a new OEM MAF for my 2012 Altima. Check engine light turned off for almost 3 months before it turned back on again with the same MAF code. Was wondering if maybe I should clean the TB? Would that help?

[@sidowsidow]

how you know the relearn process worked or not?

[@TrickShiftGarage]

You will know it worked when the engine idle is around 650 rpm +/- 50 rpm when it's fully warmed up. When I first drove it after replacing the throttle body, the idle speed wasn't too bad (between 900-1000 rpm). So it was lower than with the old throttle body (1250 rpm). Hope this helps. If you have any more questions, please don't hesitate to ask. Thanks for watching! 😊

[@rlrl4391]

What if you do not hear the throttle make that noise after the 1st step?

[@TheTruth4800]

How about on a 2008 Altima hybrid. Please help! thank you

[@adalatnawaz5793]

Hey brother! I need some advice. My sister was driving her 09 Altima coupe and suddenly it jerked then now is running rough n choppy. Starts right away, also when I opened the hood unfortunately the air filter box was open. Does this mean my throttle body could be dirty?

[@TrickShiftGarage]

Uh oh, that's not good. Some kinda debris or dirt could have been ingested by the engine. You're throttle body and more importantly the MAF sensor probably needs to be cleaned up as soon as possible (right behind the air box). There's MAF sensor and throttle body cleaner that you can buy at your local auto parts store. Is there a check engine light on?

[@andriy2562]

it that right 84 inch lbs for that bolts?

[@TrickShiftGarage]

Yes, 84 inch lbs is about 7 ft lbs of torque. Thanks for watching! 😊

[@katholderbaum7950]

Lol i had already done the math

[@SaintIvo]

This won’t work with a 3.5 engine?

[@TrickShiftGarage]

No, this works only for the 2.5 engine. Thanks for watching! 👍

[@robertellis1281]

This doesn't fit the 2008 Altima 2.5 ? Anyways that's what it says on Amazon ? Any help please thank you

[@ms1durfl]

I replaced my throttle body because my car would start but sounded horrible and when I pressed pedal I got nothing. Replaced it and still nothing. Any clues? It’s got new injectors, fuel pump, spark plugs, o2 sensors etc

[@TrickShiftGarage]

Hmm sounds, like replaced all the usual suspects lol. Is it throwing any trouble codes?

[@ms1durfl]

@@TrickShiftGarage no that’s what’s got me confused, no codes.

[@TrickShiftGarage]

Interesting. My guess would be either a bad ground somewhere in the electrical system or a defective ECM. Check over all the wiring and make sure nothing is unplugged or loose. Any wires that are showing the copper core is bad and should be replaced or repaired. Personally, I would take this issue to a shop and pay the diagnostic fee to have them tell me what's going on, and then see if you can do the repair yourself or pay them to fix it.

[@ms1durfl]

Can you not replace the throttle position sensor?

[@TrickShiftGarage]

Unfortunately not, it's built into the electronic throttle body itself. Thanks for watching 😊

[@lur3950]

Looks like you like to repair Nissan Altimas 2.5 2002 It takes me up to 20 times to start engine. There are detonations during this process. Finally Starts with hesitant revs little by little picks up & gets going. Strong gas smell. I have a p0300 code, p0720, p1574, p0138, p0118 I don't know what I can do?? Anybody knows what I csn do?

[@Jonathan-uq5bf]

Just fyi For the 2013 nissan 2.5 liter engine, the location and part is a little different. Since they changed the design of the altima in 2013

[@chuckmiller6462]

I can’t drive it at all after I changed it

[@TrickShiftGarage]

Is it starting up? Any trouble codes?

[@wesf543]

Same, very slow acceleration now from a complete stop. Once the car is moving it runs fine. Was fine before i swapped tb out, minus the up and down idle in park. Feel like I'm not doing something right

[@sidowsidow]

I have nissan 2008 and its 130K miles on it. havingAccelerate problem, it does not go above 40 mph ( and no more than 2000 rpm) … Specially going up hill … however, it looks OK when start car and drive for like 3 minutes, then I get car getting acceleration problem … I have no check engine error, no code errors …. Sparkplugs, transmission fluids all done few month ago …so frustrated , any help appreciate

[@TrickShiftGarage]

Wow, sorry you're going through that. To be honest, there could be a few possible causes to an acceleration issue. It could be a bad throttle body. But it could also be a fueling issue, i.e. fuel injectors, fuel pump or fuel filter (that's inside the gas tank). It could also be a transmission issue, a bad sensor or malfunctioning solenoid. You should probably take it to a shop and have them diagnose the problem to get to the root cause. I'd hate for you to buy parts and throw them in the car hoping it fixes the problem. Let us know if you figure it out! 😊

[@mikeblaz]

@@TrickShiftGarage I think when it doesn't go above 40mph (approx) may mean the Altima entered "Limp mode" which may indicate Transmission problems (Wants to protect the Trans) Of course it could be sensors etc.

[@TrickShiftGarage]

Yes, it could be that as well. Thanks for the suggestion Mike!

[@mikeblaz]

​@@TrickShiftGarage Off topic a bit and another thing I learned the other day about the FOB. (I didn't know this) If your car is locked and you press and hold the unlock button it will make your windows go down till your release pressure on the unlock button. This is great for me with these hot temps. I just lower my windows from the house so I don't have to enter a baking over car. (2009 Altima SL 2.5)
