P0720 output speed sensor in Nissan and infiniti problem

[@TrinityParaziader]

I hate to tell you, but both sensors in the front of the valve body are input speed sensors one and two. The output speed sensor bolts to the back of the transmission and takes it's signal of the park pawl. You have to remove the extension housing to replace it. I did that already and that is how I know it's there. That didn't fix it and I ended up having to replace the TCM on the valve body. Here's the thing, there is a lot of "refurbished TCMs and valve bodies available on Ebay and they are dirt cheap. You get what you pay for. If you scroll down you will notice that all of them are made in China. If you like doing the same job twice then that is what you will buy.

@@TrinityParaziader hi mate I always prefer to buy valve body from Nissan I did this before 2 time after market valve bodies are wasted.by the way I never seen input sensor outside in these models i think 1 you are talking about it’s crank sensor with 3 wires

[@sheldonunrulygaza2395]

My car having the same problem what the name of the parts you replace

[@KWADONE]

Same issue with my Q50 I replaced the speed sensor and I’m still having the same code pop up Does this mean the tranny needs replaced?

[@akdov9149]

been doing research and suppose that you have to change the valve body , lmk if you have figured anything out , having that issue right now on my q50

[@R-A-H_-]

If you have changed the valve body, and code still pops up then it’s time to change transmission. People often change the transmission before spending money on a new valve body with a new sensor, it’s more convenient. And it’s 50/50 with changing the valve body. So your wasting money if the new valve body doesn’t work, you can spend 1k on a new transmission and never have the code again

[@R-A-H_-]

And no, neither changing the valve body and transmission won’t need to be programmed, unless you get the wrong part

[@АндрейИванов-ж4э]

P0720 is a output speed sensor DTC. Output sensor located between AT and transfer box. Why you tell, that sensor located on valve body? It is input speed sensors. Or I am wrong?

[@brownmechanicsdxb]

Yes you are right but this car is 2wd no transfer case 2nd there is sensor in front output shaft before propeller shaft but this valve body have built in 2 sensor input and output.

[@ricardoherrwra1559]

So the output sensor is not inside the valve body?

[@jkjjkj08]

Hi I had the same problem and fixed. Any idea why this issue comes? That too in my 98000 kms only car

[@brownmechanicsdxb]

Because of ATF temperature this part get fried

[@jercelabellana2396]

Do u need to reprogram the tcm that comes with new valve body?

[@brownmechanicsdxb]

Not required

[@Erik9264581]

as long as its the same stock VB, if you use another model (ex. Q50 Q60 G37) then yes it will need reprogram.

[@Berto3.7]

@@Erik9264581 do you know if i need to program my 3.7 q50 i swap it to a 2019 3.0 trans and its drives shifts hard when going to gears and car doesn't go pass 80 or after 3th- 4th gear

[@nyifizzabostick1376]

I have a 2017 Infiniti qx80 car not shifting into gear 3 & 4 any help with that?

[@abuGhassan-]

1Check the trans fluid level 2 if oil is old and black change it as well Before do no 1 and 2 scan with scan tools look for any code

[@ricardoherrwra1559]

Does anyone know where the output sensor is on this car?

[@faalam]

Nissan patrol 2016:P0720 (out put speed sensor) P1807 (VHCL speed SEN-AT) any suggestions need to change valve body or transmission.. kindly assist as this happens 2000km away from my home..

[@faalam]

Vehicle gear are not shifting and can go up to 55 Kmph and RPM is at 3

[@brownmechanicsdxb]

I can’t say exactly anything without checking.but if transmission is not repair from 2016 till today and you crossed the mileage up to 250K KM then go for full transmission replacement.otherwise drain the oil check if the is clutch burn smile or metal particles.

[@Cookieboii]

I’m having the same issue with my 2015 q50 base 3.7 I replaced the speed sensor but I have the same issue

[@brownmechanicsdxb]

Did you check the wiring harness or found any metal particles in transmission oil

[@albdabs710]

I’m having the same problem and it’s 65k miles on the trans , all my friends are recommending a different transmission not from q50 but eithe g37 or vr30

[@12MRJERSEY]

​@@albdabs710It's the TCM, not the transmission.

[@albdabs710]

@@12MRJERSEYyessir but a new tcm cost just as much what the shop charged me for Vr30 trans swap on my car, I wasn’t gonna run the same tcm just to go through the same problem again that is very common with the 3.7 trans

[@busalove2013]

​@@12MRJERSEY. It's the valve body! Very expensive!

I have infinity qx4 2000 and my part looks way different can you tell me is it the same or not thanks a lot

[@brownmechanicsdxb]

I think its 2 wire sensor located on the transmission before the propeller shaft

I'm having rhe same symothons on my g37 do I need to replace just the tcm or valve body?

Do you have same falut code

[@fahadhamdan4426]

I got same this issue yesterday on my car QX50, it's means same problem!! I have to change the valvebody or sensors only Please inform me I checked I got same code P0720

@@fahadhamdan4426 yes it’s can

[@mohammedabdulla8494]

⁠@@brownmechanicsdxbi have got the same exact issue that mr. fahad’s got it. I have got infiniti qx50 with same problem code .. so can i only change the speed sensor (the small black part with the 2 pins or i have to change the whole control module?

[@brownmechanicsdxb]

@@mohammedabdulla8494 yes if it’s located outside the valve body.only switch can be replaced this car have built in sensor that’s why I replaced full control valve

[@joseisraelmejia1174]

i have a infinity g37x 2012 and the speedmenter doesn’t work but i don’t have any lights on it’s just doesn’t show me my speed

[@brownmechanicsdxb]

If ECU getting speed signals trough Abs it’s will shift the gear.check the fuses or might be instrument cluster have problem but first you have to check speed signals trough obd

[@mujtuu]

hello bother i have a 2013 nissan patrol platinum its sometimes not shifting gears and showing 4wd light, i already change the acuator motor but still problem doenst shift properly help me

[@brownmechanicsdxb]

In platinum most of the time wiring issues come up try to check the complete wiring harness between TCM and transmission/4WD underneath

[@mj12mj]

Hello brother I change the full gear for my Nissan patrol platinum and still this code showing (I installed used transmission) kindly help me out what can be the problem now?

[@brownmechanicsdxb]

Do have problem in shifting I mean you changed because of only fault code

Yes it can be replace only speed sensor but before you need to check properly the falut and live data
