WARNING: This page is about a different car, the 2009 Honda S2000 and 2008 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.
Mounted under the driver's side of the dash, the TPMS control unit receives pressure sensor ID signals every time the vehicle speeds exceeds 28 mph (45 km/h). It also receives signals from the transmitters for tire pressure and the sensor condition, and it continuously monitors and controls the system.
