It's annoying when on occasion they rotate the tires but then forget to reprogram the computer so it knows what wheel which sensor is on, this requires a tool: <https://www.amazon.com/dp/B083XJSK8K/ref=sspa_dk_detail_3?psc=1&pd_rd_i=B083XJSK8K>

They, instead, detect "low pressure" by noticing the different rates of rotation of the tires (based on the ABS sensors). ("poor mans TPMS") These "self calibrate", in a sense. Move a low tire and it will see that the new location is rotating with an effective smaller diameter than the others and flag *it* as being low (regardless of where it was previously located)

If just the module fails you can usually save the tire by pulling and de-flating the tire a bit then slipping the new module around the stem & hopefully can get away without re-balancing the wheel if you do this in your driveway> They, instead, detect "low pressure" by noticing the different rates of > rotation of the tires (based on the ABS sensors).

I don't think the reading is that real time is it? When you've blown a tire, do you really need a dash gauge tell you? -- Rick C. - Get 1,000 miles of free Supercharging - Tesla referral code - https://ts.la/richard11209

That is why the tire pressure won't show up until you are something like a quarter mile down the road. It needs a few rotations to fire up the pressure sensor. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209

When Ford says loss of control they really mean it.

I'm also used to the slow leaker that needs airing up every month or so. The last time I got a new set of tires I foolishly thought I would miss the ever popular valve stem charge. Nope, they charge for 'rebuilding' the transmitter.
