90 zr 1

[Bill M.]

Can anybody tell me if the tire pressure sensors in a 90 ZR 1 are the same as a standard corvette?
thanks Bill

You don't want to need any of these sensors. The one for each wheel is different and all are GM-discontinued. A lot of these are damaged when some klutz mounting or de-mounting tires fails to take appropriate precautions.

Joe you mean they are not needed? This is my friends ZR1. My sons CTS V traction control went nuts when 1 of his sensors failed

I don't believe there is a way to disable the LTPMS from what I have read. There are many used and NOS sensor out there with some at reasonable prices. The previous owner of my 1990 had all 4 replaced by the tire company when the young technician failed to read the warning labels on the rim and broke all 4. Needless to say the tire company lost on that sale.

Just checked the GM parts system and as joe said they are all discontinued. FWIW here are the part numbers:

10098494 right front
10098495 left front
10098496 right rear
10098497 left rear

There was a good Restorer article detailing how any sensor could be altered so that it would function at any position. The text of that article can be found in this thread:

There is this post on the Corvette Forum. He has 3 of them FS (RF, LF, RR) and from the looks of it he is open to best offer. (Note; I am not connect to this person or his post).

No, I did not mean they are not needed. I just meant that you don't want to need any since they are GM discontinued and expensive if you can find any.

They have to be position-specific so that the computer knows which wheel is low pressure. Some cars use a system that only tells the driver that one of the tires is low but I believe the C4 Corvette system tells which tire is low.

Re: 90 zr 1

Bill, make sure you get the big hose clamp that holds them on the wheel. The link in post #8 talks about a tap test. Do that before you have them mounted and balanced.

Joe, my 96's information center simply says "Low/Flat Tire", without indicating which tire it is, and, as far as I know, there's no other way to tell. And the owner's manual simply says if the light comes on, check all four tires. So I also have wondered why the sensors are different.

I guess my belief that the system indicated the specific tire is incorrect. I always thought that was the reason for the different sensors. So, now I don't understand either why there are different sensors. I have no personal experience with the system as I did not order it on my 1992. I just figured it was the kind of thing that would probably cause me more grief than benefit. ZR1 owners didn't have the option, though.
