I have a 2007 RAV4 Base 2.4L AWD,
I want to see the tire pressure on all 4 wheels, maybe even the outboard spare.

I see these wonderful gadgets that monitor their own TPMS sensors.

Rupse TPMS Tire Pressure Monitor System with 4 Sensors Displayed on Your DVD Monitor

and I wonder can I get one that listens to the OEM 315Hz (I think they are 315) and just gives me a display in the cabin. That way the stock TPMS light does its thing, and I will happily know what the pressure is in my tires without walking around it.

Anybody heard of anything like that? anyone?
:) thanks

Well those were examples,

I like the one that connects to a video input on the back of my aftermarket stereo headunit.

What I was looking for was a device that would go into the vehicle, that I could train to listen to the stock TPMS sensors so I could preserve the stock system -and- have a display of the TPMS.

Here's the thing, two problems to solve. Frequency and Sensor serial number.
If i could get them all to agree on frequency, i could get the aftermarket sensors serial numbers put into RAV and life would be cool
The monitor would listen to the same signals the RAV was using and give me details I want.


Freq RAV 315hz and the aftermarket examples are 433hz


Has anyone seen an aftermarket TPMS monitor (knockout, DVD, or dash/windshield mount) that uses 315hz?
315hz and 5 tires would be nice.

alternatively,

This one uses external valve cap sensors, and at 433 would not interfere with the stock sensors.
Only question is whether they have brass or aluminum threads. The stock TPMS on the RAV uses aluminum stems which apparently have a reaction with the brass threads. Have heard they will weld themselves together.

And there are still only 4 but I could keep them only on the active tires and skip the spare.

I've not heard of anything like that. However, I can recommend one of those race-car type round tire gauges like Tire Rack sells. They are pretty accurate. But you will have to walk around your car. And stoop down too. :egad:

You can monitor tire pressure levels in real time using Techstream. It shows each TPMS sensor's serial number and the current pressure. You have to figure out which one is left front, right rear, etc. I know which one the spare is because I keep it at a higher pressure than the rest. It even shows tire temperature and condition of the sensor's battery. I understand nobody wants to have a laptop or Windows tablet in the car just for this, but it does show that the data is right there on the CAN bus and can be read from the OBD port. Now if only some clever Chinese programmer could design a module to send that data over Bluetooth......

That's what I don't get.
The data is there, but nobody has figured out how to read it with Torque, or the Scangauge, Ultragauge, etc....

We can even read the trans temperature with Torque, but nobody has figured out the PID for the TPMS

LOL! Pretty much the way I handle this "problem" too!
