Checking the tires definitely requires a good tire gauge. The wheel sensors are pretty accurate. I have a 2016 with a very slow leak in the front right. After about two months, I'll get the warning. Once I pump in the correct pressure and drive the car, the warning will remain on for a few minutes, then go away.I have a 2016 low mileage. Air is right in tires and warning stays on. I assume it is a faulty sensor but it doesn't show which wheel is low. Anyone know how to find the correct one.
Didn't know they could scan it. Thanks.I'm not sure the TPMS works on the 453 the same as it does on my 451's. A bad sensor will cause the warning light to flash for a minute and then it will stay on steady. Mine is on constantly now and it's not worth $100 or whatever it costs to get it replaced. I know how to check tire pressures like I have for a hundred years. I was worried when it first kicked on, but I went to a NAPA and they scanned all four of my tires for free and found that my left front sensor was bad. And it will stay bad into the future as far as I'm concerned.
