TPMS False readings
« on: August 20, 2018, 10:59:03 am »
HELP!!! I have a 2013 Mazda 6 estate Diesel.
My TPMS keeps giving false readings. This started around 6 months ago when I replaced a tyre since then TPMS goes every day. I have replace all tyres now with identical make and size. Also I have taken car to a local Mazda garage who have carried out several tests and can find nothing wrong. They have run a full global diagnostic check( no current faults showing). ABS system check,reluctor rings checked. diagnostic reset of TPMS and Body Control Module replaced and coded. I emailed Mazda and their answer is go to a Mazda dealer (at my cost) who will check and report back to Mazda if required. Does anyone have any ideas how to resolve this. Thanks

Whenever you replace a tyre or check pressures you should reset the TPMS system. This is done by holding down the button located on the dash, right hand side of the steering wheel. Mazda also recommend that when you change a tyre, only fit the same make as already on the vehicle. The system on the 6 works by measuring the rotation of the wheel rather than a loss in pressure, and different makes of tyre with different tread patterns can cause the system to go off.

You can turn off the TPMS  completely or get your dealer to do it.
You don't really need it  if you check your tyre pressures  weekly  with your fluid levels. You will soon know if you have a flat by how thd car handles as we have always done since we had cars.
A lot of these things are gimicks by the manufacture  to up the price and  add  to the toy list when selling the car.

Do we need Satnavs, automatic braking, radar cruise control, use of mobilephone whilst driving, to see what tune is being played, that Istop charging screen  and many other  toys , No we don't.   
Though what would help is better design and QA of the engine,  higher boot space, decent carpets and floor mats, sprung seats rather than foam rubber with a choice of colours rather than black in a quality upholstery material.

Not sure on the legalities of turning it off.  I believe it became mandatory to have a low tyre pressure warning systems in Nov 2014 (and the op's car is older than that), but maybe it falls under the "if your car has it fitted it must work" category?
