A while ago, my low tire pressure light came on, no matter how much I tried putting air in it, it wouldn't go away. Then, I realized that one of my TPS broke/shattered into 2 pieces somehow so I thought that was the cause for my tire pressure light coming on. So, I purchased a used 350z TPS to replace the broken one and had it installed, but the light still came on no matter how many times I tried putting air in the tire. I'm thinking maybe the G35 and the 350z are not interchangable? ..or maybe there's another TPS that's not functioning properly?

WTF is going on?

1. How do TPS's work? How does the car get the reading/information from the TPS to the car? (on the 350z, it even displays the actual PSI).

2. Are the G35 TPS the same as the TPS's for the 350z?

3. Is there a way to check if a TPS is working? Does the dealer have some kind of device that will say which tire is causing the problem or which TPS is not functioning properly?

Any help would be greatly appreciated.


Thanks,
Jeff

 

The new sensor needs to be programmed.

 

Needs to be programmed/initialized at the dealer......

Not really because i got volk rims off from a Z driver with 4 of his TPS, is been 3 months now and my light hasn't on. I could be wrong but i am just letting you guys know that my isn't on. I also called the dealer, they will charge $100 just to program it. I was like F.. that.

 

I see your problem here. You need to put a cover on that TPS report. Did you get the memo?

 

ya thanks peter

 

New or used TPS from another car still needs to be reprogrammed to "your" car. If you've driven your car for more than 30-45 mins duration and your TPS light hasn't come on, there might be something else wrong with you TPS system.

 

I got 4 TPMS that I can sell. But like others said, the dealership has to pair the TPMS sensors with the module using a pairing tool. They charge a lot for a little amount of work. And they charge a lot for the sensors too....I think they want 130/ea.

 

Is it true that the Fix n Flat product can damage TPS?

 

Is there any place I can get the TPS reprogrammed other than the dealer?


Thanks,
Jeff

 

Other than the dealer...not sure. My colleague does have a pairing tool at his desk since he was working on a protoype TPMS for MY09 Chrysler Corporate. Right now he's in design phase and trying to get the sensor to pass a random vibe spec...1000G RMS!

He said the tool costs about $600 and I'll ask him where he got it, but I believe it is on loan from the customer...

 

I'm not about to spend $600 on a "pairing" tool.. Anybody know if there's a way to disable the tire pressure warning light?

I know this doesn't fix the problem, but I'm just curious.

 

The TPS doubles as a valve stem but for those with aftermarket wheels, it can still fully function completely enclosed inside the wheel if strapped on. There's a hole that measures the pressure and if that's clogged with say foam from the flat repair product, I can see it not functioning.

 

Do you know if there's a way to disable the tire pressure warning light?

 

^Unfortunately I don't know. I went through the trouble of strapping on my TPS on aftermarket wheels. I figured wheels and tires were too expensive to repair/replace if I happen to not notice a flat before driving off somewhere.
