I finally spent a few min to map the TPMS ID to the correct tires position. How accurate is the PSI reading from the tires to the system?
I use a small hand held digital gauge and set it to 32PSI but the display from OBDII is 33.4. I know from experience that 32psi from the handheld rides very nice and comfy - so it may have read low compare to OEM?
Anyone can check and compare?

Sorry if this was posted elsewhere - but I can't seem to find out where the TPMS reset button or nav menu is in a 2013 GX. I got under the drivers footwell but couldn't see anythign and looked around page 636 or so in the manual, but didn't see anything about a reset button. IS there one in this years model?
Thanks in advance!

No reset button ... in some Eurasian markets 10-19 have the button for second set of tires.
Do you have a light on or recent tire swap? Codes or program with something like Techstream or 3rd party tire store programmers
OBD Link can pull the codes for TPMS

I will try to check later today... I've been really pre-occupied with home projects and mods on my new ATV

I got a 3 year extension VSA to the CPO (2 years left) so hopefully they replace under that if this is sensor failure.

There are built in diagnostics if you want to try
Remember the OBD connector is actually in this orientation under the dash
"E" below shows an example of the flash pattern for say Code 13 and 33
The chart at bottom... the trailing numbers (11-98) are the ones you could find via this OBD method.

My crappy odb2 scanner shows no codes.

Only ones I can vouch for are Techstream and OBDLink

GX460 Tire Pressure Monitoring System?
Hi everybody, quick questions. I need some experts on the Gx460!
Do any of the trims in 2nd gen GX460 include a tire pressure monitor with a readout of PSI for each tire. I'm in the search for a used GX460 and it may sound strange but this is absolutely necessary for me to have a in vehicle.
From what I've found online it looks like the 2020 and up versions definitely have a readout of tire pressure on all trims. Are there any packages or maybe the Luxury trim from the 2015-2019 versions that include this tire pressure monitor. I've read and watched countless reviews but people seem to barely touch on the instrument cluster and whats included.
Thanks!

2020+ you can see on the dash

No worries :-).
.. you can also pull the air temperature in the tire from the sensors as well with that product
Also a way to obtain your TPMS IDs without dismount with a decimal to hex conversion... if someone needs this reach out... just another conversion but OBD link represents the tire ID in the incorrect format but can be converted
