Help! LTP Warning System

QUESTION!! LTP Warning System

I have a 94 coupe with 50000 miles.
Whenever I drive the car I get a warning light that says to service the LTPWS.
It takes a while for the warning to come on. It does not appear as soon as I start driving the car.
I have never recieved a low tire pressure warning.
I have tried overinflating the tires but this does not stop the warning from appearing.
Any suggestions or ideas.

The "Service LTPWS" light means the LTPWS has failed not that you have low tire pressure. If the system was working and pressure was low the "Low Tire Preessure" warning light would come on.

Obtain the factory service manual, then troubleshoot the system per its instructions.

Hal is correct, the LTP system has failed, either one of the sensors in one of the wheels has malfunctioned, the receiving unit, or the DIC. Read the codes and it will tell you which wheel has the problem. Both the LTP and the Service the LTPWS lights come on after the corvette has exceeded 25 mphr or after several minutes, even if you don't have a flat tire. It resets after the engine is turned off, but will illuminate again as you start anew. The sensors in the wheels are no longer available from GM, therefore you have to purchase a used one. There are several posts on this site about the TPS and the ones that are specific for your year corvette. Use the search function.

Hope this helps.
