Nissan 2.5 Liter (QR25DE) Throttle Body - Full Cleaning Guide!

[@josephdoxy8670]

Watching this video did help a lot cleaning the throttle body on my 2014 altima . The two hoses attached to the throttle body are coolant hoses. I didn't realize this at the time. I did not use the relearn instructions because it seems like the computer corrected itself.

[@twelvepercentitalian2511]

You’re lucky. Mine did not on my 2012 Altima. It’s just an irritating process to perform.

[@billrimmer5596]

U would think that someone wants people to take their car to the dealer. What a crazy way to discourage people from working on their car. I have two scan tools that r supposed to do the relearn. And they didn’t work on a 2000 V-6 Altima. I finally gave up. But I am encouraged by your video. Thank u!! I have one I am working on right now. Yikes!!

[@wmonroe21]

Dude! In applications like this, a steam machine does wonders with half the effort. After spraying that throttle cleaner on, point that steamer nozzle onto the dirty area and watch gunk dissolve. Re spray throttle again and let dry. Good as new!

[@detailedbyj_]

Relearn Turn ignition switch ON for 2 seconds Turn ignition switch OFF for 10 seconds Turn ignition switch ON for 2 seconds Turn ignition switch OFF for 10 seconds Make sure gas pedal is released Turn ignition switch ON and OFF Wait 10 seconds for throttle body to make noise Let car run for 30 seconds to make sure car is still warm Idle air relearn Turn car off and wait 10 seconds Make sure gas pedal is fully released Turn ignition switch ON and wait 3 seconds Push gas pedal 5x in 5 seconds Wait 7 seconds and HOLD gas pedal in 20 seconds until CHECK ENGINE LIGHT STOPS BLINKING and is SOLID Once CHECK ENGINE LIGHT is SOLID turn car within 3 seconds Turn car on to IDLE for 20 seconds

For me, the idle ran higher than normal until I managed to get the idle relearn procedure down. I don't think disconnecting the battery overnight will do much for it. Thanks for watching! 👍

Do you have to do this procedure with all cars? For the throttle body

Hi everyone! It's the same procedure for hybrid vehicles? I have a 2008 Nissan Altima hybrid.

Hello there, since the hybrid Altima uses the same exact throttle body as the non-hybrid Altima, the procedure for removal and installation should be the same. Thanks for watching 😊

[@halflife2000]

i guess battery voltage at 12.9v when car is turned on?

[@TrickShiftGarage]

No, while the car is turned off. Has to be greater than 12.9 volts or the relearn procedure won't work. Thanks for watching! 👍

[@mattmgarza]

you probably don't have to worry about that unless your battery is really weak or something, you should be fine

[@halflife2000]

I've read the service manual and it says "Battery voltage: More than 12.9V (At idle)".at least for nissan primera p12 anyways a battery have an issue if its charged over 12.6 v which is 100% status

[@PiyalPushpakumara-y2u]

even if i clean throttle body , do i have do relearn ?

[@deebohoodrich4613]

I have a 2017 Nissan Altima Sr and I put a code reader on it the code P2119 came up does that mean I need a new throttle body or can I just clean it? And no my engine light hasn’t come on

[@TrickShiftGarage]

Code P2119 looks like a bad throttle control actuator. It could be carbon build up preventing it from opening and closing properly. I'd clean it up first and see if that fixes the issue. If that doesn't work you'll more than likely have to replace the throttle body. Hope this helps good luck! 👍

Hmmmm, I think something is going on with the engine, check over your spark, fuel and air, make sure they are good. I don't think it's your transmission, sounds like you keep up with the maintenance pretty good. It's hard to diagnose things like this because it could be so many different things.

[@tg3889]

Could this help with the P0101 code?

[@TrickShiftGarage]

Probably not as the throttle body is down stream from the Mass Air Flow sensor. I'd go the other direction and check your air filter, if it's really dirty or clogged up it could be the root cause and replacing it should fix it. If that isn't the case make sure there are no air leaks in the intake system, check all over for any air that could be entering. Check the electrical wiring and connectors too. If that looks good then clean the MAF sensor with some MAF sensor cleaner. And finally if that doesn't work replace the sensor 😉

[@rigobertochavez3578]

Actually Nissan recommends to clean the throttle if you have a check engine on. If this doesn't works, you have to update the ECM software.@@TrickShiftGarage

Eliminate the EGR valve. And your throttle body will stay clean. ;) So will the rest of your engine.

That seems insignificant. At least it’s working without other symptoms.

[@cumshot247]

Prolly because it can actually read it now. It didn't fluctuate before because it couldn't tell. It doesn't mean you're getting worse gas mileage.

[@WormSplatters]

I believe it’ll fluctuate based on how you drive. If it says 30 miles left and you’ve got the pedal to the floor then it’ll probably actually be 30 miles. If it says 30 miles and you’re going a steady pace or even downhill the number with go up a little bit since at that very moment you’re using less gas. It just calculates it based on your average mpg
