RPM sensors are different to TPM.
TPM usually integrated to the air valve stub rotates with the wheel and transmits that data wirelessly.
RPM sensor usually hall effect based sits close to the wheel sense the magnet field of a small magnet which is embedded to the wheel assembly. This is used mostly for ABS, traction control and may be for other fault detection scenarios
Fun fact: disconnect the RPM sensor in one of the wheel and ECU will totally disable the Traction control and you are on your own. Drift or drag or donut or whatever. But don't forget to connect it back once you are back on the road
