Dashboard not reading TPMS

Sensors are working and can be read with a sensor tool. There are no lights on, on the dash. However when I scroll over my diagnostics I have no Air pressure reading, for my tires.
I have tried the reset button and waited for the three blinks of the warning light, both with the truck running and just in the on position.
What would cause this and what is the fix???

 

Have you taken it for a drive? My pressure doesnt read sometime until I take a short drive.

 

Go old school........

 

Yes I have doesn't make a difference...

 

Thanks, Not sure I understand this though...

 

So lets start at the beginning. Have you done anything to the truck, or did it just stop working one day?

 

Did nothing, they just stopped working. I had the tire light come on that said I had a problem. Went to check the display and had 4 lines with no PSI. Checked all the old school way and 1 was low, (had a screw). Got that patched and still nothing, for the display...

 

After I hold the button down I have to drive for 20-30min for them to show up. If not, you probably have an issue.

 

Are you getting dashes for the pressure? That means that the sensors are there, just not reading. You may need to have the sensors scanned and manually entered.

 

The sensors tend to lose their locating function before anything else. They probably won't auto-locate on their own but like you said they read pressures fine. Either manually program their location or replace them to get the auto-locate functionality back.

 

Well there is definitely a problem, I will try that...

 

I am getting dashes...

 

I had that issue when I swapped sensors for my new wheels. I deleted what was there, and reloaded the numbers manually and it started working. The sensor IDs are stored in your TPMS ECU. The scanners are supposed to be able to read and load them. It doesn't always work. Techstream is the Toyota app that allows you access to the data. You can either get the techstream software and cable and manually load the sensors yourself or take it to Toyota and have them do it. Or if you happen to be in the Jax area, you can swing by my place.

 

Where are you located?

 

Near Jax/St Aug

 

Sent you a profile message.

 

how long of a drive did you try? After hitting the reset button, it takes a certain amount of time for them to report back with the locations and pressures. Hopefully its just as simple as meeting that time requirement.

 

It's totaled. LOL

 

Did the shop remove the tire from wheel when doing the patch? They could've broken a sensor, replaced it, but not successfully program the sensor ID to your ECU
