2019 Tacoma TPS Sensor what the heck

Dont know why my sensors have stopped displaying on my 2019 OR. i plugged in my carista obs2 and i can see all 4 sensors are reading fine, tried the steps to get it to reinitialized like 5 times, unplugged battery, and re saved the id numbers of the sensors and still nothing.

Anyone know what it could be? thanks

 

Plug a scanner in the obd2 port and check for any tpms codes.

 

thx but no codes, and scanner sees the 4 sensors with correct tire preasure readings. the gauge cluster has had the ------- readings for about 2 days now

 

Is there a sensor in the spare? 2nd gens had one and it had to be at pressure.

 

hmmm let me check

 

ok no sensor the spare, and no error codes found, on the carista app i can see all 4 sensors working, but my display gauge on the truck doesnt detect any.

 

i can see that the monitor receiver is working by looking at the obd2 app just not getting to the trucks information screen.

i drove to big bear towing a boat, and right near the end of the trip the light came on flashing?

 

here is what i see

 

The dashes are a placeholder until tire rotation sufficient to activate reading. If the system has them registered and the batteries are good, then it should read after a few moments of driving. If not, look for codes as well as “pending”. If you leave your OBD2 reader connected, try removing it to make sure it’s not interfering in some way. I forget, but I think it’s 3-4 starts no sensors unrecognized before it throws the error. (Noted from a tire swap I did).

 

Ok thx the above picture is pretty much what i see on mine.

I have driven at different speeds and also remove my anything camera to see if it had something to do with it. I will give it 2 more days then off to the stealership, i wonder if its covered under warranty

 

Did you try pushing the TPMS reset button at the bottom of the steering column? You will still need to drive it a few miles after hitting the reset button to see if that fixes it.

 

yea hit it a few times, when up in big bear and also around my area. i will disconnect the obd2 and see if it comes on within 40 miles of work today, if not off to the dealership.

 

From what I recall, the reset tells it only that the locations may have changed and to note the ID (from the table) to location.

 

See if you can get a status of tire position pid for each sensor. Looks like they got stuck in Judging state

 

Do u know how i would do that?

 

I use OBD Fusion and techstream for maintenance and monitoring. Not sure how Carista works, but here are Pids that tell tires position
Also check if anything is causing an interference with the radio signal.

 

Ok took it to American tire co and turned out to be a broken stem, the sensor was just floating around inside the tire. All work now thx for the help
