I have the low tire pressure indicator on my corvettte, and would like to know if anyone knows how to either reset it, or remove. I currently have 30 psi on all four tires, but low pressure indicator will not go away.

Probably one of your wheel sensors are bad. If you have a C-5, that should be easy to fix, from what I understand. If you have a C-4, difficult. On C-4, each wheel at its position has its own unique sensor, and would be very involved to figure out which one is bad, besides, I don't think that any may be available from GM.. I have a similar problem, good pressure, but the light shows up. Ignore the lite, put a piece of black tape over the lite. or pull the bulb, mentioned somewhere on this site on how to do that.
You can find the bad sensor by selectively lowering tire pressure on one tire at a time to 20 lbs and driving a mile or so. A bad sensor will noirmally NOT set the light on.
But if all the tire pressure is correct, and the message, LTPWS appears, it has to be a sensor giving a faulty reading.
This may work: if you change all the tires out for ones with no sensors, I don't think you will get a message. At that point just keep replacing a tire one at a time with a tire that has a sensor, when the message appears, that would be the faulty one.
Aha. LTPWS means Low Tire Pressure Warning System is in error. In my 89 that tells me that one or more of the sensors isn't responding. However the working sensors can still throw a Low Tire Pressure alarm. By selectively lowering the pressure on each tire yiou can find which sensors DON'T set an alarm - they're the culprits. That's how I found I had two bad sensors. I bought them from another CAC member.
Thanks for the info. My message comes on as soon as I drive the car for about 10 min. If I lowered the pressure, the message will come on anyhow. No?? Or if I lower the pressure in each tire, selectively, the bad sensor WILL NOT make the message come on?? Is this correct? Thanks again.
Mine is a '96. I have a code scanner, that I got from Pep Boys. My understanding is that these codes would not show up. Don't remember what my results were(brain freeze). Are you saying that if you jump the connector the codes wioll show up? Thanks
Thanks I'll try this. But not too soon now, I disconnected for the winter. Lucky we hit 30 tomorrow, and salt dust on the roads. Aah, so. cal
