air pressure sensors

What will happen if wheels (with snows) without the tire pressure monitoring system is used?

On my 04 you have to disable the VDC or the car goes into limp mode.

I don't have TPS's in my summer set up. The TPS light comes on after about 30-40 minutes of driving. It doesn't affect anything, but you need to get used to the light being on.

Wow, I tried it on my car with the stock wheels. As soon as I took off the car went into limp mode and would not let me drive over 5% throttle or over 5mph until I turned off the VDC. Then I could drive and after about 10 minutes the VDC, ABS, and SLIP light would come on and stay on.

I looked in my ESM and found out that these sensors are part of all those systems.

I think you're confusing the wheel speed sensors with the tire pressure sensors.
The tire pressure sensors transmit to the BCM through the remote power door lock receiver, there's no connection to the VDC or ABS systems.

^+1..yeah, I think ttrank misread it...he knows a LOT about cars.

Oxymark...like Philly said, the light will come on after about 45 min. of driving, but will reset itself when you turn the car off....it will then come on again after more driving.

Let me ask a dumb question since my '03 G doesn't have tps and the '07 G will. Are there good selections from after market wheel companies that make wheels compatible with current cars with tps? I'm hoping to go 19" or 20" with my new G. And if so, what manufacturers should I look for as the car becomes more popular? I'm thinking the offerings from Infiniti are going to be very limited and probably won't go over 18", at least not until the new G coupe arrives.

Unfortunately, I'm not unless they are two in the same. I took off my 20's which have the TPS from my sport 17's and put back on my sport 17's with no TPS. That is when everything I described above happened. I went back home and put my 20's back on and everything was back to normal.

The only way I could drive with out my TP sensors was with VDC off.

I would suspect it was caused by a change in tire diameter or stagger. Seems more likely than the TPS.
I've switched out to winters with no sensors and had no problems at all, but my winters are exactly the same size my summers.

The VDC engaging is definitely due to the change in tire diameter and not the TPS. The TPS has absolutely no effect on the VDC system. The VDC is so sensitive on these cars that you can set it off by not having the same make and model tire front to rear. The tire diameter ratio can even change enough to set off the system just by having one completely worn rear tire and one new one (learned this personally after running over a nail, getting a flat and trying to replace just one rear). I have a good friend that is a Nissan service tech that told me they get 350's in all the time with VDC issues due to tire diameter changes.
The TPS system doesn't even "communicate" with the car unless one of the sensors is "activated" by low pressure. If you do not have the TPS sensors on the car, the light will not come on - unless the spare has low pressure (not all spares have the TPS though).
When I got my Enkie wheels, I looked into putting TPS sensors on them as well as the stocks, but thought the $400 would be better spent else where. The only sensors that will work are the Nissan sensors @ $100/each.

Not sure if this answers your question, but there are aftermarket wheel manufacturers whose wheels will accept the OEM TPS's. You'll just want to do your homework w/ the place you buy the wheels from and confirm that your TPS's will work/fit. When I bought my 19" Milano's, the guy told me that my TPS's will work/fit in the Milano's, and sure enough, they did.

That is not true. It gives a description in the ESM about how it constantly communicates pressure via radio signal and has a different warning when one of the sensors stops communicating.

Yeah, my sensors are in my 20's. My friend at Discount Tire said the stock pressure sensors from most cars will fit most aftermarket wheels.

You are correct, I just found the proof. There is a CAN system interface chart in the ECM and the TPS is not listed as an input to the VDC/ABS systems.

I need to go back and check the tire size on my stock wheels, they must be different.
