Tyre pressure sensors

[ShannonG]

Howsit guys. Juat a quick question. When I start up my clio 3 rs Gordini the spanner light comes on and notification of tyre pressure sensor faulty. Any idea of where exactly the sensors are and how to test them to find out which one is actually faulty?

Thanks

They're inside the tyre bolted to the back of the valve.
