Thread: OEM TPMS integration?

I think by mandate in the states here, all TPMS systems operate in the 420mhz range, correct? Can the sold system in the store (receiver board)be made to learn existing OEM TMPS systems, or is this even operating in that range? I could of course yank the data from my CAN-bus, but I'd rather get it direct from the sensors when they're transmitting.
