i just bought a set of c5 wagon wheels for my camaro and don't need the sensors that where in them. is there any way to tell if they are good? i would like to sell them but i will not sell anything to anybody if im unsure of the condition. any help is appreciated.

 

you should be able to go to any local tire store and they can check them and see if they are good. they should have a TPMS sensor scanning tool to wake up the sensors and see what freq. they scan at.
or even a dealership... hopefully for free

 

Wal-Mart is carrying TPMS equipment in their shops these days. Just swing by and ask them to see if they work.
