Five Minute TPMS Relearn Using Reset Tool For Nissan Frontier And Xterra
Vložit
- čas přidán 2. 04. 2021
- In this video a TPMS relearn tool is used to reset the four tire sensors in all wheels on a Nissan Frontier/Xterra 2005-2019. This has been found to work on early 2000 Nissan vehicles like the Pathfinder, Nissan Z, Altima, and more.
The relearn tool is around $13 and the whole process takes only five minutes to complete. There are many of these types of tools out there but I purchased this one from Amazon.com. The Nissan Frontier/Xterra TPMS computer can only set four sensor so a spare tire or summer/winters tires cannot be set.
The tool that is used is a VXDAS model and has a transmit and low battery LED. The device can read 315 MHZ and 433MHZ sensors.
Note:. If pointing directly at the stem does not work try moving it down to the tire and left to right on the tire. the TMPS senor is about 3 in long so moving it around may help get the roll over the device that's inside the tire. - Auta a dopravní prostředky
Okay, so this worked for my 350Z. I bought the same tool and after about three years of dealing with that annoying blinking light, I finally got it fixed. The blinking light would eventually go solid. I used a paperclip to connect to the TPMS connector just like you did in the video. The connector is under the passenger dash. You have to remove some panels and use a Phillips head screwdriver to take off a few panels on the side of the floorboard. It's super easy, and there are plenty of videos showing how to do this part.
Like others mentioned, I had trouble getting the light to blink for more than a minute. So, I ended up deflating the tires as recommended: 34 psi for the front left, 31 psi for the front right, 29 psi for the rear right, and 26 psi for the rear left. I don't think this step was necessary, though. I probably just messed up the sequence initially and was trying the old method by driving around. Then, I saw your video last night and had the tool overnighted to me.
Today, I tried again with the same lower psi in each tire. This time, I was able to force the TPMS into relearning mode (continuous TPMS flashing past 1 minute). Following your video, I pressed the button the same way you did, and, no kidding, the hazard lights came on for each tire, and now the light is off. I didn't even have to drive the car. When I turned the car on, the light was steady and then turned off.
Once I get it on the road, I expect the light might turn solid again until I get the correct tire pressure. I’ll post an update, but I’m so stoked. I've wasted too much time on this problem for far too long.
Hey just glad that my video helped.😅
I know what you mean about wasting a ton of time... My video on front end noises came about because my radiator support bolts were loose and rattling my front end over uneven road. I did many hours of testing until I found one post where someone had said that they removed the front bumper and had to tighten those bolts due to similar sounding frontend noise I had. After all that I built the video covering the problem.
Update due to the deflated tires the light did come back on. However once I added proper air pressure in each tire with the car running after the last tire I check the dash and the light is off. Been driving it all afternoon and night multiple restarts no light! Again this is the best way to do it! It’s way better than the old way.
Great to hear!
Thanks so much for this. I was tired of the grounding / staggered tire pressure technique and I was sure there must be an easier way to do this.
I agree it can be tedious and if you don't get tire pressure just right you drive around 15min for nothing. If you are switching winter and summer tires this device for around 15$ will pay for itself in time not spent having to drive to set the sensors.
Thanks for the information. This worked first try for me no problem. Less than 11 bucks delivered and no more trips to the local tire shop for this. 👍
Great.
You may also notice when the battery starts to diminish you won't get a great read right away and will have to get closer to the side wall. I have one set that has great batteries and another set had poor batteries and eventually I could no longer read them.
Took me 3 minutes todo all four! Thanks man, super easy and quick
Awesome.
Thanks brother I just purchased the same one for my Pathfinder.
Let me know how it goes. It should work just fine but maybe won't work on the latest model.
New Sub. 2007 Frontier 292k odo. TPMS stays lit solid even proper inflated. Thnx
If everything is probably inflated then one or some of your sensors are bad. If they are more than six years old then it's probably time to replace them.
@@autoxadvice4159 bought new, 17 yrs old now. I will buy tool n test out. Like your blue fronty ! Thnx for quick feedback !
Sounds like you will need new ones but buying the tool is cheap and you can use it on any vehicle for 315mhz TPMS.
Thx appreciate you stopping in and committing in my truck.
Thanks for this video. Question for you, if I have to replace the TPMS Sensors on my 2007 XTerra (batteries on current sensors are dead), and purchased a set of new Nissan Infiniti OEM TPMS sensors (315 Mhz), do I have to do anything other than install on the rims, reinstall tires, ground the reset connector, and use the VXDAS transmitter to have the car learn the new sensor frequencies? I'm getting different stories from my mechanic and from Nissan as to whether the new sensors need to be programmed in some way first.
If they are new 315 MHz sensors from Nissan there will not need to be any special programming. Just follow the process you outlined and what is in the video. The only time you need the special programming are on some other vehicle models or when the sensor is a dual sensor (315 & 433mhz) which will do multiple vehicle types/
Good information
Thanks for stopping by and leaving a comment.
Thanks for the great information.
Just a quick question. In what order do the tires need to be programed? I saw that you started at the front right tire but not sure which tire you went to next.
It appears I wasn't clear on the programming sequence.
Riders front
Riders rear
Drivers rear
Drivers front
Thanks for stopping by and watching.
That work for programed new sensor ? ?
As long as the sensors are already set to 315mhz yes it will work. If you buy dual sensors for 315mhz and 433mhz then you would need a programmer that would set them to 315mhz first.
What pressure would you set your tires at before using the tool? Is it the same staggered settings if 36,33,29,26 psi?
When using the tool the tire pressure didn't have to be staggered like I mentioned in "free tpms reset" video. I would advise to air them to the pressure required so that all tires are ready to go when you complete the relearn.
Thanks for stopping by and watching the video.
I cannot find the white wire I found a clip on the obd but it has multiple wires coming from it and I have a 2014 Altima sv
This procedure may not work on your Altima. This process was made for the Frontier/Xterra/Pathfinder. It could work on some of the other models, but not sure on the 2014 Altima.
I can’t successfully ground out the connector with a paper clip like you’re doing. Every time I try, it blinks until a minute and stays solid. I can’t get it to keep on blinking passed then minute mark.
What vehicle are you trying this on? If it's the Frontier I could only suspect that your paperclip isn't pushed in far enough to touch the end of the white wire. It's either that or your sequence of events is too slow.
My 2015 Pathfinder has that connector but it has 4 wires, any idea on which one or ground all?
Interesting. I would have to see an electrical layout.
Id suggest that you go out to nicoclub.com and pull your model service manual. That SM should have what that pin connector is used for and more details of pin out.
my 2006 frontier has a leaking schrader valve on one of my tpm units,can I just replace the valve?😎thank’s
Yes you can get a tool to remove the valve without having to pull the whole tire tpms valve.
Thanks for the video. In an XTerra 2013, I got the first step right as the tpms light starts to blink, but after that I cannot get the arrows flashing, even for one tire, I have tried the device from all positions. Would it be that the tires sensor batteries are too low? I just tried again and now I cannot even get the tpms light to flash anymore, I am doing the same steps. Any recommendations are appreciated, thanks.
Yes, it can be the batteries on the tires are too low. What I've find is that of you get 8yrs out of the batteries then that's about as good as it gets (depending on the brand). Also, I've find that with new sensors I can point the device at the valve stem, and has batteries age have to move the tool closer to the side wall of the tire.
If you want to make sure the device works as it could be bad you could order some TPMS sensors for your X and test the sensors before they are installed. You should be able to go through the process with the sensors out of the box. Watch out for programmable sensors that can do 315 or 433 MHz sometimes you need a special tool to get them programmed before use.
I think the sensors' battery were the problem since I got some to work but not all, I've ordered new sensors, thank you!
No problem.
I’ve followed this several times on my 2013 Frontier and I can’t get it to work. I have the tool and can get the truck into relearn mode but the tool does not reset the sensors. Reading the comments, it seems as if positioning is key, however I feel as if I’ve held the tool in every possible position. Not sure what else I can try or the the sensors are actually toast
How old are the your sensors? If they are more than 8 yrs old then they may have low batteries. I had to do all 4 sensors on my winters because the batteries were so low the tool wasn't able to sense them.
Now with that said, have to tried to position the tool lower on the side wall (rubber) away from the end of the valve. The sensor more in middle part of the rim anyhow.
Last resort is to buy new sensors (like at Amazon) and then test just to make sure your TPMS tool works.
How to use this tool in Nissan Versa S 2019? I have this tool but I can't find the wire for ground.
More than like your versa doesn't have this wire. Look in your owners manual and see if there is a way to trigger the reset. Sometimes there is a dash button or other process to do so.
Hi, Amazon describe this tool as for GM vehicles (Chevy / Buick / GMC / Opel /Cadillac) But do you think it will still work on my 2010 altima? Thanks!
From my reading the 2010 Altima TPMS operates on 315 MHz the same MHz as the Frontier 2nd gen. So if the device reads 315mhz it will work. With that said if the reset procedure in the Altima is the same then the device you are getting "should" work, but can't guarantee it. If you read through the comments here others have confirmed other makes and models from Nissan.
@@autoxadvice4159 Great! I will give it a try then. Thanks for sharing!
Can't find the reset wire on my 2010 Nissan Rogue. Any advice?
Check out this link www.nicoclub.com/service-manual?fsm=Rogue%2F2010%2FWT.pdf
Its the Nissan Service manual for the 2010 Rogue. On page 9 it shows the reset wire under the dash.
I don't know enough about the Rogue so I am just going off what their SM states. If you cannot find it directly under the drivers leg check inside the fuse box too as it maybe behind there.
Good luck and let me know what you find.
2020 Pathfinder has a bunch of wires and the connector is mounted. Is this method obsolete in this case?
I suspect that with later model trucks outside the vq40DE that it will be different unfortunately. The new 3.8 in the Frontier is different and this process will not work, as an example.
What years of the Frontier would this work on? I have a 2008.
This should work on 2005-2021 Frontiers, and 2005-2014 Xterra.
Would this procedure work for a 2013 NISSAN Altima?
I'm not 100 percent about how to do the reset tpms procedure on the Altima, but the reset tool will work as the Nissan Altima sensors are 315mhz. Let me know how it goes.
Got the identical Tool in your Vid. Unfortunately, it did not work. The EL-50448 did not interface with my 2008 Nissan Xterra via the flashers. The EL-50448 TX light did not flash as well when I pressed the button. It simply lights up, but does not flash. Any additional suggestions?
How old are the sensors? Also, I've noticed on sensors that have low battery you really need to move the reader down to the tire sides. This year I had to replace all four sensors on my winter tires as they all had very low batteries, I thought the reader was bad. Replaced the sensors and the reader read all just fine.
The reader, unless it's bad should read all 315mhz just fine.
Bought new tires at Discount Tire just before Xmas. The said they “rebuilt” the sensors. I made sure about that because I had the tire light on for ~ 6 years. I bought the car used back in 2016. So, i cannot swear that they are original. I tried the manual method multiple times, but obviously no luck there either. I appreciate ur maintenance vids. I believe I am subscribed. Thx for posting
Here is what you can do. Buy a set of Amazon with free returns, then test them out and see if they work. If they don't work, I'm assuming your reader is bad, if they do work then the sensors are bad.
I can't think of a reason why this should not work and since you mentioned the manual way doesn't work either (which can be finiky) then I'm thinking sensors.
Good luck and let me know how it turns out.
Hi. I replaced only one TPMS in the left-front whell, which was the bad one, according to my mechanic. I have the same tool, and I followed your video, but the blinkers flashed only with that TPMS. I drove now for over 30 miles, but the dashboard light is still on. Any ideas? Thank you!
The reset process requires all 4 tpms sensors to check in. What you need to do is to make sure the other sensors check in with the blinkers flashing to confirm. If the batteries are low in the others you may need to get a bit closer to the sensor. Move the tpms tool lower on the tire away from the valve stem. Try that. If that doesn't work you may have batteries too low to operate.
Thanks for stopping in and asking.
@@autoxadvice4159 Thank you, this makes sense. As I was I was trying another other time, actually 3 of the sensors blinked.. But not anymore. Let me try your advice.
@@autoxadvice4159 YOU ARE AMAAAAAZZZZZIIIINNNGGG!!! Thank you so much. Getting the tool up the tire a couple inches away from the rim edge helped. You da boss-man, boss 😁 Since you are so nice, do you know how to set a 2012 Prius C into the relearn mode. This car is new to me, and pushing/holding the TPMS button does nothing. I cannot find any good info. Thank you!!!
Great to hear it worked for you. The only thing that I can you on the Prius is probably what you already found out on the internet. Sounds like you need to turn the car to the On position but don't start it. Then hold the tpms reset till the light comes on on the dash. Good luck on that one.
Cheers.
I have a 2008 frontier . I bought a new set of 4 and that tool at Amazon. Will it work with that tool? Just like you explain? (Brand: Marsflex)
If you bought 315mhz sensor then yes.
If you haven't installed them yet you could try this whole process with them outside the tires but they do need to be spread out a bit.
It worked, I paid $100 to have them installed in all 4 tires, and then I use the tool and light went off. Thank you so much!
Great to hear it works.
I just bought the same TPMS tool and did the procedure however I have no flashers go off on my 2008 Frontier 4x4 Crew cab? The low pressure light flashes even after scanning each tire. Then when I turn the key off and back on again the tire light stays lit solid.Is there a time limit on how long you have to hit each tire with the scanner?
How old are the tpms sensors?
I've noticed that if the tpms sensors are lower (med to low) on battery you will need the tool pointed not near the stem but lower on the sidewall of the tire.
If you have the system in the relearn setup and point the tool around the be tpms sensor you should hear a confirmation of the 4way flasher click. That indicates the tpms sensor is recognized by the TPMS computer. If the 4way flashers do not click then it means that it did not recognize the sensor or battery is dead.
@@autoxadvice4159 Great I will give it another try and I've had the truck since New and yup they are original sensors. Thanks for your quick reply, I will update you once I try again.
If those are the originals I'm going to say you received everything out of them and are due for new. 😆
@@autoxadvice4159 Well you are 100% correct 15yrs not bad, but I had no idea they had a battery in them! Is there a brand name you recommend I usually buy from Rock Auto. Thanks for the help from up here in Vancouver👍
I don't. Though OEM lasts, I just did not want to drop 80$ on them so I bought some aftermarkets.
Hello I have a 2010 Nissan Rogue and was curious if this tool would work on my vehicle because I’m trying to stop the tpms light from blinking then going to solid on my dashboard
If you can put the computer into reset mode and the sensors are 315mhz it probably will work. It's been reported that this procedure will work on Altima and Maxima. I can only assume that it will work for Rogue as Nissan reuses lots of parts across platforms.
@@autoxadvice4159 how do I put the computer into reset mode
It would be like I showed in the video "if" you can even reset it like that. I haven't worked on a Rogue 2010 but you also could have a reset button too. Check under your dash for the connector.
@@autoxadvice4159 do you have an email address so I can send you a picture of underneath my dash cause I’m trying to figure out which one deals with the tire pressure sensor

I wonder if this will work with Nissan Altima 2012?
Nissan did carry over different electricnic components across models. Which makes sense to save time and money.
Check under the dash for a single white connected wire. That would be key. Let me know what you find.
Will this work on a 2015 infiniti qx80
Does it have a white reset plug under the dash or a dashboard button to reset? If they do, I could only suspect it to work as I haven't tried that model.
Anybody have experience programming TPMS on a 2022 Nissan Kicks?
I haven't heard on most of the newer models. Some cars have had their own reset button you may want check what the owners manual says for the tpms light.
Though if you are having issues with the light yours is still under warranty and I'd take it in to get checked out.
If my light is already blinking do I still need to ground the white connector
Yes that starts the reset process.
Thanks for replying. I have the orange tool and tried the process. Now my tpms light starts on solid and don't blink. The reset tool does blink the red low battery one quick time after the green light finishes. on each tire. Thanks
So the process is to turn the ignition on but start the truck. Ground out the white wire six times. The tpms light will start to blink. Then use the reset tool at each wheel. Once the wheel tpms is learned the 4-way lights will fash.
Now you may have to move the tool around near the valve stem and below over the outside tire in the area where the tpms sensor is.
I had rotated my tires to winter tires last night and this worked for me.
I’ve tried this yesterday after getting my new oem tpsm installed. It didn’t work
Are you sure the tpms installed was 315mhz or if it needs to be programmed to use 315mhz.
Also you may need to move the scanner to the tire below the valve. I've found that my Nissan sensors require this more than my aftermarket. My aftermarkets are more point at the valve, where my OEMs are more of moving over the outside of the tire.
Will this work on the 2016 Altima?
I've heard it will work on some other nissan's but I haven't tested it. I belive if you read lower in the comments I've talked to one person that had tried and it did work.
On my 2008 Nissan Sentra the flashers don't flash for any of my tires , Do you have any advice ?
Does any of the tpms sensors replay a buzz, chime, or beep? It may not be there 4 way flashers on all Nissan models.
You could have a dead tpms sensor. The tool I show in the video wakes up the sensor to start reporting and the tpms computer will capture that tpms ID.
@@autoxadvice4159 I have the same tester as you do , Have you ever had a tire sensor display a low battery light ? , I did not get a low battery light on any of the sensors , they are probably all the original sensors, I do not think that I heard a chime or a beep , but I will double check tomorrow . Thanks for the advice.
During usage of the tpms tester none of my sensors tested as a low battery. I do winter summer tire change over so at some point I expect this to come up.
UPDATE , After doing this relearn process a few times , I finally got three out the four sensors to wake up and trigger the 4 way flashers , I do have 1 totally dead sensor , I believe that these are the original sensors so I am going to replace all of them with Denso Brand sensors. as far as the low battery indicator on the tester , I read on another website that the indicator is for a low battery on the TESTER. Thank You for your responses and help.
@@asportsnut1960 thanks for sharing your experience with the Sentra relearn. I'm going to check into that looks battery indicator. I was under the impression it was for indicating the sensor has a low battery. However, since I hadn't had a low sensor I could not test it out.
Thank you. The VXDAS tool does not work on my Pathfinder - new battery in it :-(
What year Pathfinder? Does it have the reset under the dash? Are the batteries good in the tpms sensors. Did u try all 4 wheels and move the device lower below the valve stem on the tire?
I'm not sure this will work on the newer model Pathfinder works on the P w/vq40de.
@@autoxadvice4159 Thanks for the response. It is a 2012 R51 LE. The tires are from my brother's Pathfinder and work on it. I will try what you suggested
Alright Sir, got it working. It was the way I held the device. If the valve stem is up, device needs to face the ground. If the valve stem is down, device needs to face up. That worked for me.
Thanks for the video again
SWEEEEEEET. I had that situation as well where I just pointed the device at the top of the valve stem and nothing happened. The actual sensor is down in the tire along the outer tire sidewall.
Cheers
I have 2020 frontier and have no small connector by OBD port any suggestions?
I haven't worked through a 2020+ Frontier tpms reset. Id have to look it up. Sorry can't be more helpful.
Thank u f reply. dealer said 170.00 it's not under warranty:(
I guess we need to figure out the cheap and easy way. 😂. I'll take a look when I have some time.
Any update, also have 2020 pro and swapped with new sensors
I've read through the 2020 owners manual and that wasn't helpful. The MHz (communication) frequency is still 315 so I suspect that the TPMS unit is still the same one that was used pre 2020. So somewhere there needs to be a reset and I suspect that it's still there maybe tucked away nearly into a wire harness.
The 2021 model TPMS model was updated to 433mhz so this is why I think 2020 still uses the old system.
Id have to find the 2020 service manual in order to figure out further.
It is for pathfinder 2006 too ???
It should be as. Check under the dash first to see if you have the white single connector to start the reset. Nissan TPMS all (at least a lot of their models) run on 315mhz so the procedure should work.
Let me know how it goes. Someone recently asked for their Sentra and the procedure worked for them.
Note:. If the tpms battery is dead it will not provide a horn beep, a 4way flash click, or other noise, indicating the sensor was set.
Followed these steps with my 05 350z, everything goes as planned and i have pressure readings until i restart my car and they go away. Do you know what i might be missing?
So turning off your 350z and back on your TPMS pressure readings all go away? Does your TPMS light illuminate show a rising light (or other injection)?
If you are losing your TPMS data by turning the car off then it could be an issue with the tpms ECU losing power (like a disconnected battery). That's just my initial thought.
@@autoxadvice4159 The TPMS light goes out after i sync all four wheels, and didn’t come back on after restarting the car.
If you’re right thats a bummer, sounds like a bigger issue. I’m going to redo the steps again a go for a drive to see if that changes anything.
Yeah try the steps again. It's really odd that the sync of the tpms works (though I have never done it on a Z to confirm), but then fails at a restart. The only thing that I could think of is the Z maybe requires a final step or a fifth wheel tpms like a spare to complete the TPMS sync. Though still odd you get the pressure readings to appear.
@@autoxadvice4159 So after a couple days to confirm this process does work on the 350z. When the car is started the gauge cluster will read blank until a few minutes after the car has been in motion. After the car moves the TPMS info appears on screen. I don’t remember what exact TPMS sensors i have in my winter wheels or if that even affects anything. But i have TPMS readouts again.
@steveshaeffer6850
Ah yes... That makes sense. Most toms sensors don't announce their presence until the wheels are in motion. This process conserves the battery.
Where do you get that tool? I need that
The TPMS tool was purchased off Amazon.

Hi, this'll work for 2006 nissan pathfinder??
As long as the Pathfinder has the white plug under the dash to reset the tpms system.
Thanks for the quick response boss.
also do i need to have new sensors??
You need to have good working sensors. If your current sensors are more than 5-7yrs old you should consider new ones.
Thanks a lot
Sure thing.
👍👍👍👍👍
👍👍👍👍😁
FYI and anyone else. YOU DO NOT NEED TO ADJUST THE TIRE PRESSURE IF YOU ARE USING THE CHEAP TOOL. KEEP IT AT THE REGULAR PROPER PRESSURE.
Hey, there is no reason to yell. We are listening😅
i did couple of times not working. no luck for now
Can you go into some more details of what sensors you have? Did you hear the clicking of the four way flashers. You could possibly have a bad sensor (s).
Anyone's done it on a 09 Sentra? Thanks
If you can reset the tpms system through the cable I show or a button. Also, depends on how new too.
@@autoxadvice4159 ok. I need to check the car and also check the manual
This doesn't work on nissan pathfinder 2019 .there's no plug
I have been made aware that the plug was removed on the 2020-21 Frontier and this is probably what to expect on the Pathfinder too.
I have an old xterra (2006) Ive seen in other CZcams channels how “batteries” are dead . How do you tell if this procedure will work or if you need to do something else with sensors themselves … meaning I don’t know but I can’t imagine batteries as the power source . But maybe this other CZcamsr just confused something else as a batterie …. Hint this guy didn’t replace anything he just blocked the light via taking the instrument cluster out …. Which I’d rather save as a last resort , but dont wanna buy a specialized tool no matter how cheap if it hasn’t got a chance at working due to some other issue in the system.
Also looking on amazon there are many models of that make of reset tool . Even a couple at $13 that advertise as gm or Ford etc but not Nissan. But if you read description most say Nissan , no other species like car models or years … I guess if you have the model number of the tool that’s be great , but if not does just that range of hertz mean it’ll work ?(all assuming my above comment doesn’t negate the necessity for for the tool ie : needs parts replaced “battery” or whatever ) thanks
315mhz is what you need as that is the frequency the tpms operates on. This tool has a low battery sensor detector but it doesn't directly detect a dead sensor. However, when you walk around to each wheel and do the sensor read the 4-way flashers will blink and click. If this doesn't happen at a certain wheel then that is a bad or dead sensor.
Here is the exact reset hardware that is used in the video.

@@autoxadvice4159 thanks
What if this doesn’t work?
If it doesn't work then you have a low battery or dead TPMS sensor.
@@autoxadvice4159 I have new sensors that were supposed to be programmed and ready to install when I got the but they are not doing anything

You are welcome.
Now I am working on the Air Bag Blinking light. I may have to surrender this one to Nissan. Yuk!
Never give up.
How old are the TPMS sensors? If the battery is dead then yes you must get them replaced and they will reset the sensors for you.
I got you on the airbag. Go to airbag 360. I assume it’s the passenger seat sensor. They make a bypass connector. There is two wires down below the seat one for the seatbelt and one for the airbag. It’s just plug and play. I have on 2008 350z. This works I’ve had it installed for over month now. I’m about to try this trick right now on my z but the TPMS switch is under the passenger dash.
