I saw a video on the internet on how to change the battery on a TPMS Sensor for a 1997 Corvette. It contained a 3 Volt Lithium Ino Battery. I have a sensor out on my 2004 Escalade and thought that I would take one apart and see what's up. The battery for the sensor on the Vette was like $1.65. I will let you know what I find. Has anyone done this?
