The Nissan Path

These little bastards are starting to run out of battery.

1 is bad, 2 are low battery and one is reading fine.

How the F can a 2007 with 57k on it have sensors that the battereis wear out? I would think they would have more than a 5 year lifespan? Federal Law requires them but how about how long they are supposed to last?

They want around 500 to replace them.

I was thinking about using a 3 cent piece of black tape and saying F it.

Honestly I don't need a light, I have been driving for 30 years without sensors and know when to check and fill. Tis so damn annoying to see it blink for a minute then go solid. It doesn't help my OCD either.

That's exactly what I would do. Nothing.

I just had one go on my 06. They seem to last about 5-7 years. Dorman Products makes them on the aftermarket and work just as good as OEM. If you search around, you can find them for $50 each and I believe they have a lifetime warranty.

I had one of mine replaced recently at no charge by the dealer, '07 w/53k. The battery on it wasn't bad, but it kept sending out a fault code. I personally hate the things.

On my other cars I use the tire pressure caps. They have a preset rating. If your tires have good pressure you see green when you glance at them. If your tires are low you dont see green. There are no batteries or sensors to fail. Just a easy way to tell if your tires are low. $30 for a set of four

My new 2011 SV came with the TPMS but they also gave me Nitrogen in my tires and free services for one year on the Nitrogen. I have almost 6000 miles on it now and had it since September. I have not lost any pressure nor did I have to bring it to the dealer for refill since I have the truck.

FYI - at the beginning of winter, a customer comes in - tire light
tells me how much we're rippping him off, scam scam scam etc etc.

He's on the way back home form vaca, lives in the mountains - snowy as F*** already. Tells me his wife (sure...) popped a tire and had it replaced, he's guessing tire shop damaged sensor or something. They checked it out, replaced the tire, got half way home - light comes on.

I check it out - whole time he's nagging me.

long story short - he had a cracked rim, had spread (i'm guessing partially due to getting wet and freezing) 2/3 of the way around the rim. F'n hub center was gonna fall out if he kept driving.

TPMS prob saved his whole fam from driving off the moutain road.

How common are cracked rims on Pathfinder's?

Not very common, but it can happen. The TPMS is a good system it's just that they should have had serviceable batteries in the sensors. You can check your tire pressure everyday but that doesn't gaurantee you against picking up something in the road and have a fast loss of pressure in one of your tires. Most of us remember the Firestone tire problems on the Ford Explorers years back. This system is a direct result of those problems.

I've noticed mine are getting a little more sensitive with age, but all of them still seem to work great. 05 with over 140000mi on it. I've never replaced any of them in the 5 years I've had the truck.

I prefer to have a fully functioning TPMS system, I'd replace the sensors. I've managed to save 2 tires because of this system, where it warned me of pressure loss before the tire was damaged from running with no air in it. System pays for itself.

I'm thinking of replacing all of mine sometime in the next year when my LTX's finally give up. Well...if they give up!

What's the current best price? I see $50/unit from Tire Rack and elsewhere.

Rockauto.com has had the best prices on TPMS sensors that I've found. Of course, once you get the new sensors and have them installed, they need to be "woke up" and ID registered. To wake them up, you'll need a TPMS activation tool. I've been thinking about this one for $80:

I already have a scantool that'll work on the TPMS system. I've also looked at this one for a bit more money, but more features:

Score! Thanks! They had a couple on close out for $25. I bought both, I'll have the one replaced and just hold the other for the next time. B-)

Dunno if my scan tool will work with TPMS, but definitely worth checking out...

Thanks for the tip on where to get inexpensive TPMS units... I just snapped TWO trying to take off my metal valve stem caps that had just enough corrosion on them to freeze them on there a little too hard. It was like they were made of butter. The first one I admittedly forced but the second one I hardly even twisted.

I was hoping they were a two piece type design where the stem just snaps into the TPMS to secure it to the rim but apparently not.



Uhg... shops just love it when you bring them parts & say "Install this, please".

Are there other ways of waking up new TPMS without buying a tool?
