TPMS sensor ID from another Toyota you own

Not sure how well that will work. Maybe, since it's second gen, the tech is a little different. My 3rd gen) scenario:

When I've got the winter tires (without sensors), the all-season wheels (with sensors) are stacked in the garage, just feet from the car. Every time the car's driven into the garage it reacquires signal, but when the car's driven the light comes back on in short order.

It's a little light, I just tough it out, lol.

 

Post it note, cut to cover the annoying light. If needed black electrical tape over it. The post it note doesn't leave behind sticky residue like electrical tape or such. Can be peeled off easily. Love post it notes.

SM-T700 ?

 

Neon post it notes....not sure if it'll be an improvement

 

What happens when you drive away from the other car?

 

That is very strange. Usually, my Prius Prime with no TPMS in winter tires would not lit up the TPMS light when I park my car at home. The set of summer tires with TPMS sensors registered are sitting in the garage and the car thinks they are on the car. However, after driving away from home thus away from the set of summer tires with registered sensors, the light will turn on. This usually takes about 20 min. I would think one sensor would do the same thing, but in your case, it didn't. Don't know why?

 

Maybe his commutes and trip segments in that Prius were all under 20 minutes each?

 

That's possible. But even if the commute is, say less than 10min, the car being turned off away from home and starting again later will turn on the TPMS light immediately, I would think. So, yeah, maybe on the way to work is OK, but coming home, it should trigger the warning. Maybe Gen2 TPMS is sufficiently different from newer Prius. I don't know.

 

But in your case, even after you shut off the car, and later you start car again at location away from your home, like at work, the TPMS light did not come on. That is bizarre.

 

But that is how I had understood or thought it worked. When the ignition was shut off, if the no-detection timer had not yet tripped, it was reset back to zero, to start fresh next time. But once that timer runs out just once, and flashes the warning, then it is game over until the problem is fixed. The warning is flashed immediately at each subsequent restart.

Maybe some other readers here have more experience with it ...

 

Oh, I see. In his case, the TPMS light never came on even after 20 min has passed. But that means his car was in perpetual timer reset, then it does not explain the fact that he now sees TPMS light on after his other Toyota vehicle is gone. What is the difference between parking at his work away from his house with no TPMS signal and parking at his house without his other Toyota car?

 

No. But it is strange indeed.

 

How long have you waited since the install? Or have you started the car up and gotten it to ready?

Sometimes it takes a bit to take once the sensor is there.

I have a ScanGauge II and in the morning it takes 2 minutes or so to "relearn" what the pressures are once I have the Prime in "ready".

 

Does the sensor require some sort of activation in order to start transmitting?

E.g. as a feature to prevent battery drain before consumer use, some devices that come with preloaded batteries have an insulating tab on a battery terminal that must be pulled out. A replacement smoke detector I installed last month didn't start until its first twist into its mounting plate.

Could it be that this sensor doesn't start until first pressurization, or getting shoved into a wheel rim, or something similar to serve as an activation?

 

Since registering the sensor, have you run the car for at least 10-20-ish minutes in a single continuous session? It takes a while before the TPMS alerts on a missing sensor.
