For what it's worth...........the factory service manual in its Wheel and Tire section, has about twenty pages of trouble shooting of TPMS componets/wiring. I downloaded this section of the manual from https://topix.jaguar.jlrext.com/topi...=276&id=125917

Some cost involved.

 

Have had the intermittent "Tyre Pressure Monitor System Fault" for a month now..

Decided to take a look behind front wheel arches and there it was, out of place..

My initiator antenna nearside (UK) came out of its mounting clip and was resting on the undertray, after driving through a large puddle (small flood) .


Clipped it back in place and secured with zip tie.. Problem Solved.
