Apparently, yes but I suppose we would be talking about some sort of seepage over time or an effect of temperature to do it?

But if the TPMS is initialized and then the pressure in all four tyres is decreased equally, shouldn't that still be detected by torsion resonant frequency detection, as per the Mazda pdf?

;) Yes, JT you are right - so the system should have warned me. The Dynamic element, according to the pdf, wouldn't have sent a warning but the Torsion side of the equation should have tripped the TPM.

Looks like it don't work then (just like my air con! Grrr!) ...and I'm not going to do something drastic to test it :lol: - so as far as TPM is concerned I'll just quietly sweep that one under the carpet... :|

PS Thanks for the pdf Anchorman
