Tyre pressure sensor lost (all) after RF transmit

[chtucker]

I was driving down the road intermittently transmitting on 155MHz or so on a portable transceiver at 5 watts. First time doing this. I am troubleshooting something at work.


While transmitting, I lost all sensors.

Anyone seen this before? Has never happened before on anything else I have driven with TPMS.

Seems they are temperamental. I haven’t lost them while transmitting yet, but you may have just been unluckily with a harmonic or something getting into the 433meg Tpms.
Mine just failed for no apparent reason.
Best I could find was leave it overnight and it gradually sorts itself out once you start driving the next day, which mine did.
