I've seen new ones with rubber stems for some flexibility with tpms. Might be good if you are getting into some deep stuff.

 

Acrad, you are aware that the TPM sensors will need to be programmed into the system every time you swap the the wheels (with different TPM sensors). Right?

Yeah ... unfortunate this can't be end user reset. If I can find a shop to do it cheaply I'll go that route...otherwise I'll stare at the TPMS light for 4 months out of the year. I tend to be OC about tire pressure and generally check once a week anyway.

Might need to look into this.

It's too bad these units require their own cap or internal hard coded TPMS sensors to work. I have the codes for my current tires and would be nice to install one in an unsued cutout on dash. I'd like a more real time status than plugging in the Techstream. I don't mind manually checking my air pressure but it's a shame this data wasn't included for easy viewing in the infotainment of the GX.

 

Possibly in a Lexus Software update?

 

I am on the latest infotainment rev for the ‘10-‘13 models. Fairly sure this info doesnt show up on ‘14+ either. I may need to look into some OBD based options as well.

 

Not on my ‘15 w/ latest firmware...

 

It would seem they may have added option to the '18 Prado

"The new Prado’s Tire Pressure Warning System detects low tire pressure and displays a warning on the Multi-Information Display in real time. Hence, insufficient tire pressure can be determined at a glance, and pressure refill or tire replacement can be performed with accurate and timely information‎."

 

This brings up a question that I had awhile back and still not sure of the answer. How long does it take for me to be notified that I am losing air on the GX?

The Amazon link says,

• Real-time tire pressure/temperature and vehicle battery power monitoring(Displays pressure or temperature of 4 tires and vehicle battery power simultaneously) to keep your vehicles in a good condition and reduce car accident
• Advanced American Freescale 6-in-1 wireless sensors.Sensors transmit pressure and temperature data every 3 seconds

I don't consider 3 seconds as real time but not bad.

 

I think it is something like every 1-3 minutes. Nothing conclusive in FSM but there are some programming entries that talk about there being an issue if time exceeds 3 minutes.

 

There is a brand called ORO. A Taiwan manufacture. They claim it can read tire pressure from OBD, no sensors required for most models and looks the same as this one. But sadly they're not selling in the states.

 

Might be this unit. Sensors in GX use the 315Mhz sensors.. the other seems to be 433.xMhz like this unit below

That's the product I was talking about. It's all in Chinese though. Asian companies usually sell their products on Taobao a Chinese eBay. That's why they usually have *****y website.
I read through but couldn't find any information related to frequency. They say there are different models for Toyota Lexus Nissan and Honda. I am not sure if they work on American models but I believe they will work since most Lexus are made in Japan and have same parts but don't quote me on that. I am still waiting for more information myself.

 

Yes, I would like the TPMS to show the PSI for individual tire . My NX does that but too bad the more expensive GX does NOT.

 

About 3-4 years ago I found an oem unit listed on *Australia* Toyota website. It is tiny and works with existing oem sensors. Since Toyota/Lexus use the same frequency I suspect it'll work just fine for the GX. I brought the picture to a Toyota dealer here in California but they know nothing about it. I asked a friend in Sydney to come to a dealership there: they have it, for $200 or so. Too bad for the life of me I couldn't find it now, maybe they no longer sell it.
