    Default 407 Typre Pressure system - How does it work

    I have a loaner car a nice new 407 got in it and the start up BIT ( Built In Test) came up saying I had a type with low pressure and sure enough it was correct even told me which wheel.....

    The older TPI systems relied on a pressure sensor attached to the valve stem and connected to the rest of the car ... this is not there

    any one know how it works ( PFM) Pure F####ing Magic is not the correct answer

    Its still a pressure sensor on each valve. The inertia of the wheel charges it and it send a high frequency signal too the ecu. Its a better system mainly becaise you dont have too programe where the sensors\wheels are on the car when you rotate the tyres,figures it out by itself. note-the spare on the 407 doesnt have a sensor fitted so the system logs a fault during the BIT.

    Sounds like you have to be pretty careful when you change tyres, as a lot of tyre shops just take out the old valves and throw them away, replacing them with new ones.

    Thanks Guys but I have had a look at the spare and the valve stem is exactly the same as the other 4 wheels - still dont know how the transmitter in the valve stem gets its electrical power.

    Thanks again
