Tires and Wheels problem
2003 Lexus SC 430 V8 Two Wheel Drive Automatic 49000 miles

My car has Michellin run-flat tires (PS2). I am getting a tire pressure warning lamp (steady on, no chimes) that would normally indicate low pressure. All tires are at exact correct pressure. I suspect that one of the tire pressure sensors may be defective or some other part of the system. How might I trouble shoot this problem? Do the sensors have a battery that needs to be replaced? How does one replace a sensor and then reset the system? Thanks.

Do you
have the same problem?

Hi Lexman01, Welcome to 2carpros and TY for the donation

Probable causes here could be the tire pressure monitoring receiver,tire antennas -you need to scan the computer for codes
