Just put a set of new wheels and tires on my car. Took off the TPMS sensors and have them sitting on my desk. I know at least one of them is bad. I tried using a Rhode and Schwartz FSU26 spectrum analyzer ( $65K ) to measure the frequency output of the sensors but I am not getting any readings from any of them.





Are they supposed to be putting out a reading ( mine are 315Mhz ) off the vehicle?

OK. Did a bit of reading. The TPMS I have in possession have a built in accelerometer which activates the circuit. Now I just need to figure out how to bypass that. Ill have to find a schematic

So I take it you need to put the sensors in your new wheels?

Any reason you want them?  Can you just leave them out...pull the bulb for the dash light?

My jeep jk 11 has low tire pressure light on even though all tires are 32-35 psi.

Mostly to get the light to turn off. Im going to pull the gauges soon and put a piece of black tape under the laminate of the gauges to cover it up.
