if i replace the tpmv on my 2020 1.2 panda pop will i need a diagnostic device to recalibrate it to the car on can it be done through the car systems?

Sorry there are no valves in TPMS system. Its ecu based via ABS wheel speed sensors. Put the right presures in all tyres and reset tpms in the trip computer. Confirm reset and you are done

what a cleaver little system ive never seen one use abs sensor..im so behind the times must read up on this..thatnk you very much

Dflated tyres are a different circumference than inflated ones, and the speed sensors can detect this. They can be tempremental but it OK as a warning . Tyres can be pretty soft if the light does come on so always stop straight away and check if it gives a warning light.

Had a new tyre fitted, forgot to reset TPMS
TPMS picked up the odd tyre almost immediately. Even though all were at the correct pressures.

"pressures" are not sensed per se. Because it is measuring and comparing rotational speeds the relevant metric is rolling diameter. So if your new tyre is significantly different this will be the issue - I'm not sure there is a "reset"?

i read the handbook and theres a relearn procedure throught the dadhboard.. changed the tyres without the problem thanks
