TPMS Problems...

[Oberkanone]

I've had one TPMS sensor fail and replaced under warranty. @18K miles
I plan on keeping this truck for a long, long time so I expect to replace several TPMS sensors over the life of the truck or disable the TPMS system or warning light.

Is it necessary to have the TPMS? Plus, would anyone know who I need to contact to have a new one order for my new rims and tires?

Had a light come on yesterday, checked press. 3 at 35 1 at 32. Went to indoor range to shoot and service station in parking lot. After shooting the tires had cooled so I went and aired them to 36. The 32lbs tire stem snapped at about mid thread and valve seat and air came out. This was the common push on stem type air hose valve for $.50 machine most service stations have. It was not tight and very little pressure was used, about the third time going between gage and adding air. I heard a psst/pop and was looking at half the stem on the rim and the other half on the ground with the valve seat. After putting on spare, took to dealer (2007 XE, 9.991 miles), Warranty Manger told Service Writer to right up a warranty replacement. He said they had had a few of them come in before. Its a cheap alloy, very light and thin metal and the threads are like score lines. It would have been almost a $200 repair otherwise, $120 for sensor, $20 for mount and balance and whatever for resetting the computer

TPMS SENSOR SEAL LEAK

When repairing an air leak at a TPMS (Tire Pressure Monitor System) sensor seal, a seal is now available separately.

My TPMS light came on yesterday because the temp dropped into the 40s the other night. I put about 3-4 lbs in each tire, drove a mile and the light went out. I was suprised as to how sensitive the system is.

Mine was on this morning (got down to 28 last night), will air up on the way home from work even though the light will probably be off.

Mine came on yesterday. Checked they pressure and they were all between 35-36. Nitrogen came in the tires when I bought it.

Called the dealer and didn't get a warm and fuzzy feeling about the system. Basically they said all they can do is reset the system when the light is solid. If it is blinking, there is a problem with the system.

Not sure it applies, but check Nissanhelp.com for TSB NTB08-032. Took mine in and had this TMPS issue addressed and replaced. Bring the TSB printout. To do this all you need is to register at nissanhelp and you get 2 downloads per day.

My apologies if this is old news.

...hey i was wondering about filling your tires with nitrogen. my tire stems have the green caps on them which im pretty sure means theres nitrogen in them...

i have a couple questions about it: 1) is putting nitrogen in something that you can do yourself or do you have to take it to a dealership? 2) is it ok to mix regular air with the nitrogen?

ever since it got cold here in bama my tpms light has been on but ive checked pressure on all four tires a couple times and both times all four have been atleast 35, usually 37. any help is appreciated...

Sure, actually the stuff that we breath is comprised mostly of Nitrogen. By volume it's about 80%, the rest is mostly oxygen. And the other gases are present only in very small amounts. Oh, and then there is the water vapor.

To fill a tire with N (nitrogen) we need to vacate all of the air that is inside the tire, or are we really only concerned with the 20% that is O (oxygen), or maybe it's just the 1% water vapor that might be present that is giving us any trouble. Gotta watch that water vapor stuff ....

By the sounds of things, you may have a sensor that is not reading correctly, unfortunately figuring out which one it is may be difficult, or even impossible. If all four tires are set to 35 PSI (cold) using the same tire pressure guage, and the TPMS light comes on that would suggest a failure in the TPMS system. One of the 4 sensors, or maybe it's the TPMS computer ?

Sorry, I am not really helping but I sure do understand your situation. The real problem is the presence of TPMS but near as I can tell, only the gov. can do anything about that. And since it's their brainchild, it seems rather unlikely that they will want to abandon it, no matter how BAD it really is.

I think, but do not know for sure that when new sensors are installed, the vehicle TPMS computer must be trained to listen for each of the 4 new sensors that have just been installed. That one-at-a-time training procedure might expose one of your sensors as being "bad", maybe ... I will be learning more about this in the spring when the four new rims, sensors and tires get installed on my truck. I don't know if the output from each of the 4 sensors can be read and thus determine that one unit is failing, or non-responsive.

Man I sure hate this stuff. Seatbelts ain't got nuttin on TPMS.

From what I understand about the sensors, if one is failing we might be stuck with having to replace all four to fix things, can anybody clarify this ???
