Tpms light on - reset or new sensor needed?

I was driving last night and the tpms warning light for one tire began flashing and then stayed on. Wondering if it makes sense to be trying to reset it manually or have the dealer reset it or is this pretty much a dead sensor.

The manual reset procedure sounds like a pain to accomplish and im sure the dealer will charge an arm and a leg to reset it. Should i just save money for a new sensor?

Its an '07 mo with 165,000km. Back in November i had new tires put on and replaced the tpms sensor gaskets and had the tires sealed with that tar-like paste. So they are not loosing a drop of air. I would hate to take one tire/rim apart to have this done again.

What're your tire pressures? I find I have to be at least 2 pounds over to make light go off and it takes like 10 miles driving to register.

It may just be coincedental but you should not be putting any or too much tar like paste on the bead which could stick to the sensor and block its function. Air pressure usually comes out of the valve itself anyways. Then again, one of my tire tpms sensor acts up once in a while for the past 3 years now. After a long drive it sometimes just goes blank or **. I just restart the car and the numbers comes right back up. It has always been the same tire on its 9th year now on 2 different sets. I would observe it first and maybe its just on the flactuating stage. When it fails, usually its the battery but damage on mounting is also possible. Particularly you mentioned that you approved on putting a new gasket on the sensors. I myself did not want them to touch the sensors 2 years back when I had my original set of tires replaced. Just so they won't mess anything up. If it has totally failed and you want that one wheel fixed, you will need the dealer to reset it so the new sensor will be recognized by the system. No getting around on that one. They could charge as high as a 100 bucks to reset it or as low as 25 bucks. Good luck.

To reset, you must "exceed" 33/34 psi on all tires (so try 36-38) psi when tires are cold and with an accurate tire gauge) for the light to go out . It can take a quite a few miles driving stop and go for the TPMS warning light to turn off automatically.. Adjust your psi only in the morning when it is cool/cold and with an accurate tire pressure gauge!

Once the light is out, reset to 33+ when tires are COLD. The cold part is critical so do your tire psi adjustment(s) only in the morning before driving. Remember, if ONE of the tires psi dips down to 31/32 you will see the TPMS warning light turn on. AVOID adjusting tire pressures when tires are warm.

Remember, ascertain your pressure gauge is accurate!

Re: Tpms light on - reset or new sensor needed?

The airpressure is fine. Its the sensor.

There is some missinformation here...the light will turn on at 25 psi and go off as soon as u pump in more than 32 psi.

Why would someone comment on a LE ? Its a 1st gen section.

The tar was put on last november and the issue just happened..its not the tar.

Anyway. I barely notice the light now ..just gona drive with it as its not worth fixing and doesnt affect anything....

There is no misinformation in this thread. Gist is to over inflate all tires, (not above tire psi recommended max by manufacturer of tire) and then drive until tire pressure warning light goes out. Once the light goes out, you set all tires to the desired psi. Check tire psi only when tires are cold. Of course, common sense dictates that if one or more the tpms sensor is bad then the warning light will not go off. This info is pertinent to both Gen 1 and Gen 2 Muranos.

Curious if you are so sure of what the problem is / answers should be why did you come to this forum
and ask "Tpms light on - reset or new sensor needed?" ?

yes there is, read my post referring to previous posts.

Why would i over inflate the tires and drive around like that waiting for the light to go off LOL? please stop your misinformation as well. Thanks.

andrei ........ Again, no misinformation posted in this thread. There is blatant evidence in this thread though, supporting the idea of you being to thick headed to understand, assimilate information that is spot on.

Back off, dude. The information above is correct and based on the experience of some of the most well-informed members of this forum.

It won't cost anything to air up the tires to more than the set point, drive a short trip and see if anything changes. You can safely run any pressure up to the maximum rated on the tire sidewall, which is probably 44 PSI. I run 40 PSI all around.

Re: Tpms light on - reset or new sensor needed?

Lol dont get your panties all up in a bunch guys...this billarf character clearly did not read my post or its title and has missinformed me, anyone reading this now and a billion years in the future!

How does increasing the psi from 35, which all 5 wheels are set to now to anything else make the light go away? Does he/she even know at what psi the light turns on? Or what psi my wheels were set to before recommending a certian procedure?

And to all the other readers. Please ignore his/hers "reset" procedure as it is wrong. You guys will find the correct procedure on either the titan or g35 forums...

Anyway...problem solved

I experienced the same problem 2 weeks ago. Billarf is correct in his procedure.... this is exactly what I did to turn off the warning light. The temperature went from -5c to -25c overnight and the warning light turned on that morning..... when cold you can easily loose 3-5 psi. That why everyone here is telling you to check the presssure when cold. I put few more pounds and the light went off since then. Try it !

*IF* the tire pressures are actually low, i.e. below 29psi or whatever the threshold to trigger the warning is, then you need to overinflate the tires to get the light to turn off.

However, if the tires are already inflated properly (35psi is fine), then the most likely cause is a failed sensor.

I've had a bad sensor for about half a year now. All is well until exactly 20 minutes after the engine is started, and then the TPMS light comes on, and one sensor loses the reading and displays a *. If I restart the vehicle, all is ok again until 20 minutes later again. All my tires are 38-40psi, so they are not underinflated. I've lived with the bad sensor for a while now, and quite honestly I don't care what that one tire is reading since I keep an eye on my tire pressures pretty regularly with a gauge. But that bright TPMS light under the tach is pretty annoying. I think I'll just get the sensor replaced, even though the car is getting to be that age where I might not fix anything htat does not affect safety.

How funny, Eric, I have the EXACT same situation here with my 04 SE - and even for about the same time (the past 6 months). I too am not worried, since I also run my pressures in the high 30's and check them regularly. I'm wondering if, at 8 1/2 years old, one of the sensor batteries is merely getting weak? But that wouldn't explain why only one sensor acts weird (wouldn't they all start doing this after a while?), why that one works OK for 20 minutes at a time, nor why cycling the car off and on again temporarily clears the problem. I figure replacing the sensor would likely be the answer, and would make sense to do when I next need tires. But, with only 40K miles on them, the Cooper's I put on at 65K still have tons of life left. So, since my recently purchased 335xi bimmer has become our trip car, I know I'm years away from needing new tires on the ole Mo.

At 106K miles, I had the car in this week (one of the few times in the 8+ years I've owned it) to the dealer for plugs, and mentioned this TPMS issue to the service manager. He acted as though he had never heard of this particular problem, and they did a sensor relearn (of course, at no charge). I'll see if this works.

Oh, and just for info, I thought I got a great price on the work I had done. Even without the $100 discount - which brought my $588 bill down to $488 - I was pretty happy getting plugs, an antifreeze change, and the accessory belts replaced (the latter 2 a little early, since I had them first done at 60K) by my dealer.

So after driving for 6+ months with the stupid TPMS light turning on *20 minutes after I start the car* every single time, I decided to replace the sensor. Actually here is what happened.

I was at Sam's Club and noticed they charge $19 to reset the TPMS on a vehicle, or $5 per wheel. I thought, $5 what the heck, maybe it will work. They did a reset, and no dice. So I asked how much would a sensor be? They quoted me $45 for a Schrader "EZ-sensor" made of plastic, and $59 for an OEM sensor. To my surprise, it is the exact same Nissan OEM sensor made by Schrader. How do I know? Well they gave me back my old sensor and it is identical in color and shape. So, for those looking for TPMS sensors, just get it from Sam's - it is cheaper than the dealer ($106 list, $78 online, or Rockauto, $72 online). Labor to install the sensor? $5. I kid you not. That included remounting and balancing with the new sensor. Afterwards, however, the sensor did not register with the computer, and one wheel read "0 psi" presumably picking up the old sensor in my pocket. I found a TPMS reset procedure for Nissans online which involves grounding the TPMS connector six times to enter "learning mode" but that didn't seem to register the new sensor.

So, a visit to the dealer was in order, and I expected to pay half an hours labor for them register the new sensor. But nope, surprise, they did it for free and I had driven in an hour before closing time. So, for about $65 I got one TPMS sensor replaced and reprogrammed, and all is well again.

A few trips so far over 20 minutes, and no TPMS light. So, the solution to the "TPMS coming on after 20 minutes" is to replace the sensor.

If I were to guess why the sensor is failing, it is likely the battery. The sensors themselves enter sleep mode if they do not detect wheel rotation (that is so they turn "off" when you park the car). A good sensor with a dying battery probably enters sleep mode and is unable to "wake up", although I am not sure why it only happens 20 minutes after starting the car (and not fail to wake up when the vehicle is started).

FYI, the replacement part number is Schrader-Bridgeport "Airaware" 20064 for my 2003 Murano.

Good to know that Sams club have the same sensor. One of my wheel is also a candidate for tpms sensor replacement soon. Been acting up for a couple of years now. Thanks you sir.
