These guys are really cool. He spent over an hour diagnosing and resetting using his scanning tool. Problem seems to have gone away for now 🤞
I’m in Howard county so please send me name of the tire shop and any other mechanic or custom shop that you recommend in DMV area. Would be super helpful as I need a mechanic I can trust and use the parts that I provide.

Tire pressure app
Is there an app or an aftermarket thing that I can use to read tire pressure from all 5 TPMS? My TPMS keeps acting up once in a while with a warning light on dash that flickers and then becomes solid. Instead of stopping in the middle of a trip to manually check tire pressure, it would be convenient to find out though some sort of an app or a tool while driving. My other car displays it on dash and wish GX did too.
I got all 5 sensors replaced 6 months ago with aftermarket ones from a reputable tire shop. Despite trying their best to reset them, I keep getting the tire pressure warning light once in a while which is nerve racking especially on long trips and remote areas.

If you got them from Discount Tire, their sensors are "so-so".
They only alert when pressures are below their internal setting, so the car can't know what the pressure actually is.
What pressure are you running at? I've had best results when I had Michelins at 2 psi over what the door jamb sticker says. Now that I have all-terrains, I run at 40 psi.

As old school as the system on our GX is, I much prefer this to the more advanced systems found on newer cars. My ‘19 Tacoma displays the actual reading of each tire, and all that did was drove my OCD in high gear. I was constantly trying to get all 4 to read the same psi (which is nearly impossible after driving). Ugh!!

I have 285/70/17 Wildpeak AT3W and the pressure on all 4 is set at 36 PSI. The spare is new...forgot the size, but I got the largest size that could fit in the spare closest to 285/70 - that too is also set at 36. Maybe I should consider 40 PSI like you suggested and see how it drives - will do some research.

What changes have you noticed by going up to 40 psi? I might try it before going on a road trip next week.

A little less noisy since the outer tread blocks aren't hitting the pavement as much. The ride is a bit stiffer too.
Monitor your tire temps (just feel how warm they are). The fronts will be warmer than the rears since they're near the engine and do the steering.

I'm not sure on the 470 but OBD Link on the 460 can read TPMS. I am using their bundled OBD dongle.. not all can read it.

Yes, Orange has sensors that can be monitored by a in-vehicle add-on device, smart phone, and I think a dongle device that can hook into a Android tablet if you replaced OEM screen with one of those. I believe the "dongle" device reads the sensors with Rf, and then it's monitored via BT. You then just need to disable the OEM TPMS.

This is incorrect. Although the dash only has an idiot-light, the actual pressure is reported to the pcm and can be read with certain OBD software and a dongle plugged into the OBD port. I use techstream to read my sensors when the light starts flashing, but if for some reason you don't want techstream, there may be other OBD software that can read the tire sensor data.

That depends on the brand of the sensor. OEM Denso - yes. Cheap Continental brand - no.

More than likely on the 470 as well but OBD Link read TPMS pressure and temperature fine on the 460
