Tmps issues

Hi guys,

I’ve been searching on the causes of missing Tmps info on the dash and did several manual resets on the monitoring system as instructed in the car manual. Tmps worked after rim and tire upgrade, 1 month later, nothing. I drove 40 through 60 mph for extended periods post reset and no change.. Tmps read 41 psi post tire upgrade, not sure if that would cause sensor failure. Getting my truck serviced for 10K in a few weeks, just asking for advice as I do not want the techs unnecessarily messing/marring with my rims for new sensors.

Thoughts welcomed...

Not sure why you haven't received a response, but maybe because it is actually TPMS.

 

1st manually check your tire pressure with a good gauge. If that's not it its prob a bad TPS sensor. Sometimes they get messed up by the shop during changing rims and tires. Made of cheap plastic and can crack. And most tire shops will fill tires to Toyotas specs on the door jamb not what the tires actually need

 

I had a bad sensor on one of my tires and when I hit the reset button, it lost connection with all 4. It wasnt until it replaced the bad sensor did they come back

 

Have the dealer check out the sensors on TechStream. If they have to replace one, it will probably be on your dime, with the after market wheels.

^^^Yep, it wouldn’t be the first time a sensor got cracked/damaged during a tire install and then died a short time later. I’d go back to the place where the new tires were installed and get them to walk around and check for a signal from each wheel.
FYI- I’ve swapped wheels twice now and the new pressures showed up on my dash within a few miles of normal, city driving after resetting.
