TPMS not working?

[Ezra]

New to me '10 GX460 premium. Just got it home this week. All 4 tires looked low, but the TP light was not coming on. Checked the pressure today and all 4 are between 25-27 lbs (didn't check the spare), but no dash light. I don't really mind not having a dash light, I can check tire pressure, but everything on this car works so I was surprised to find that the TPS light was not coming on.

Green caps on the valve stems, so they either have nitrogen in them, or did at one point. I am going to call around tomorrow and see if any of the local tire places do top offs.

Any idea what might be going on with the sensor?

Low pressure is right about 26 psi.

Any chance your gauge is off by 1 psi or so? You can read psi and temp with Techstream or OBD Link application

Maybe it is still just barely in the ok range? I have a scanner coming today which should give me some more information. Also hoping to get the tires topped off today.

I hooked up my OBD reader and OBD Fusion, but I can't find where the TPM readings are on there. Any tips?

Did you purchase the model year expansion pack?

Within OBD Fusion

Settings -> Purchase Extras -> Toyota,Lexus,Scion

I have seen when I was using OBD Fusion some general OBD readers not able to see extended codes. The version of OBD Fusion called OBD Link comes with it's own OBD Adapter.

Once you have the expansion you then need to add the tires as Gauges on a Dashboard.

You also have to connect to the network for TPMS

•Connect to "Tire Pressure Monitor" network when prompted
• Goto Dashboards
• Select MENU ---> Add Dashboard
• Select MENU ---> Add Display
• Digital Gauge
• Next
• PID
• Toyota, Lexus, Scion
• Tire Pressure Monitor
• ID Tire Inflation Pressure (you will have go through steps above starting at "Add Display" 5 times to get all TPMS sensors on that Dashboard you created.

I think it must be the adapter itself. When I select "Tire Pressure Monitor" network it says connecting for about 20 seconds, then says connection failed. Every other network connects without a problem.

I have the exact same issue. Next step is contacting the OBD Fusion people. Otherwise it's pretty cool software.

I've had mixed results with 3rd party adapters & OBD Fusion reading TPMS on 460. One I picked up from Romania worked (apparently had a legite ELM327 chipset in it and not a clone) as well the adapter for the OBD Link application.

OBD Link is just OBD Fusion that works with their native adapter and includes "all" of the add on packs for all vehicles.
