Potententially Mr MOT tester wont be - and a failure will be given.
Its now part of the MOT - if the vehicle is showing as having TPS sensors fitted, they must work
So how does an MOT tester know if the TPMS sensors are working. On the bike you have to be moving to see a readout, in my car they only show up if something is wrong. They don't drive a vehicle in an MOT test
